Sonic the Hedgehog
|Debut game:||Sonic the Hedgehog|
|Predecessor:||Alex Kidd series (1986-1990)|
The Sonic the Hedgehog series is a franchise of video games released by Sega starring their mascot character Sonic the Hedgehog. The series began in 1991 with the release of Sonic the Hedgehog on the Sega Mega Drive/Genesis. An 8-bit version of the game was also released for the Master System and Game Gear formats. Sonic was responsible for turning Sega into a leading video game company during early in the 16-bit era, and his first game soon replaced Altered Beast as the default pack-in game for the Genesis in North America and Europe. As of September 2009, the franchise has sold more than 50 million units.
Games in the series are developed by Sonic Team, with the exception of some spinoffs that were independently developed by Sega of America. The main programmer for the first game was Yuji Naka, who would later become head of the Sonic Team division, and the game planner was Hirokazu Yasuhara. The music of the first two Sonic the Hedgehog games on the Mega Drive/Genesis were composed by Masato Nakamura of the Japanese band Dreams Come True.
Nearly all games in the series feature a 10-11 year-old (presently 15 years old) hedgehog named Sonic as the central player character and protagonist. The games feature Sonic's attempts to save his planet from various threats, primarily the evil genius Dr. Ivo Robotnik, presently referred to on occasion as Dr. Eggman. The main antagonist throughout the series, Robotnik's aim is to rule the planet and establish Robotnikland; to achieve this, he usually attempts to eliminate Sonic and acquire the powerful Chaos Emeralds.
Sonic 1s Green Hill ZoneMost two dimensional Sonic titles are platform games viewed from a side-on perspective. Their controls are fairly basic and do not deviate much from the genre standard; the selling point of the series is the incredible speed of the playable characters, who usually have the ability to run uphill, walls, and even ceilings. Roller coaster-like loops and corkscrews are also common in Sonic games, as are giant pinball machines with flippers and bumpers which knock Sonic around like a ball. The stages are also similar to roller coasters in that many sequences involve Sonic being thrown along pre-set paths with little input from the player, which has led to criticism that the player can complete a Sonic game merely by holding the pad in one direction. However, the games also feature numerous sections involving precise jumping between platforms and avoiding of hazards, although these sections do not require "pixel-perfect" judgment and are perhaps more lenient than most platform games of the era. Three-dimensional Sonic titles feature more free movement, and controls are slightly more advanced.
The Sega Technical Institute tried to develop a "true" Sonic game for the Saturn called Sonic X-treme. This game was intended to compete with Nintendo's Super Mario 64. However, due to time constraints and issues between STI and the Japanese division of Sega and Sonic Team, the project was canceled in the last months of 1996.
Sonic 3D: Flickies' Island, an isometric, pseudo-3D ("2.5D") game, was released for the Mega Drive in 1996. Sega Saturn and Windows PC conversions followed to cover the hole of the cancellation of Sonic X-treme. They had enhanced graphics and a different sound track, composed by Richard Jacques. Sonic 3D was developed by Traveler's Tales, although Sonic Team worked on the Special Stages in the Saturn/PC version.
In 1997, a compilation entitled Sonic Jam was released for the Saturn. In addition to containing Sonic the Hedgehog, Sonic 2, Sonic 3 and Sonic & Knuckles, it also included a "Sonic World" mode. This allowed the player to control Sonic in a small 3D world similar to the Green Hill Zone from the original game; it contained no enemies and was mainly a means of accessing the disc's multimedia features such as BGM's, illustrations and even commercials. Sonic being chased by a giant Orca in Emerald Coast, as seen in Sonic Adventure and Sonic Adventure DX: Director's CutAlthough Sonic R was the first 3D Sonic game, the full leap into 3D platforming was made with Sonic Adventure, a launch title for the Sega Dreamcast console. On June 7, 2001 in North America (23 June in Japan and Europe; the 10th anniversary of the US release of Sonic the Hedgehog), Sonic Adventure 2 was launched. Both of the Adventure titles were later ported to the Nintendo GameCube (under the titles of Sonic Adventure DX: Director's Cut and Sonic Adventure 2: Battle) when Sega dropped out of the hardware market. DX was also ported to Windows PCs.
The first Sonic game to release simultaneously on multiple consoles, Sonic Heroes, was released on the GameCube, Sony PlayStation 2 and Microsoft Xbox in December 2003 in Japan, with American and European releases following soon after, and a PC version the following November. The platforming was largely similar to that of the Adventure titles, although the player now controlled the lead character of a team of three themed characters, with the other two following closely behind. The player could switch to a new leader at any time, in order to make use of each character's special skills. It sold well, but opinions among both reviewers and fans of the Sonic series were mixed.
Shadow the Hedgehog was also had mixed views. Released in the US in November 2005, it received mixed reviews from reviewers such as X-Play, for instance, who had given it a 1 out of 5, making it the lowest-scoring Sonic game reviewed on the show. Other game sites such as IGN and GameSpot similarly panned the game. One of the greatest controversies revolving around this game is the gunplay; some fans insisted that Shadow was the self-proclaimed "ultimate life-form" and did not need a weapon. Nintendo Power and Gametrailers, however, both rated it above 8 out of 10, praising the replay value. Two other controversies were the over-use of minor profanity and the fact that Sega had decided to switch to the voice artists from the English version of Sonic X.
A highly faithful two-part port of Sonic the Hedgehog made for mobile phones has been a huge hit in Europe, introducing the game to a new generation of pre-teen gamers, with respected handheld specialist Pocket Gamer awarding Sonic the Hedgehog Part Two a 9 out of 10 review score.
A few Sonic games focus on gameplay styles other than the standard platforming. The first of these was Sonic Spinball (released on the Mega Drive in 1993 and on the Master System and Game Gear in 1994). The concept of Sonic bouncing around as the ball in a giant pinball table had been used in both Sonic the Hedgehog and Sonic the Hedgehog 2; Sonic Spinball was designed around that premise.
Several racing games starring Sonic characters have been developed. In Sonic Drift and Sonic Drift 2, characters drive go-karts (kart circuits were later included in the two Sonic Adventure games). In Sonic R (1998), most characters ran on foot (with Eggman riding his Eggmobile and Amy driving a car), while in the Sonic Riders series (2006), they race on hoverboards.
Sonic Shuffle was a Mario Party-style virtual board game/party game for the Sega Dreamcast.
Sonic Chronicles: The Dark Brotherhood brought Sonic into the world of RPGs for the first time, mixing turn-based combat and story telling with traditional Sonic elements.
- See Rings
Whereas most Rings were small and easily collectible, certain Rings appeared that were much larger. The so-called "Giant Rings" were hidden in the stages and designed to be jumped through, which would transport the character to a Special Stage, where the character could collect one of the Chaos Emeralds or, in certain circumstances, Super Emeralds. They were used for this purpose in the games Sonic the Hedgehog, Sonic CD and Sonic the Hedgehog 3 & Knuckles. Sonic the Hedgehog 2 used Star Posts instead. In Sonic the Hedgehog 3, if all the Emeralds had already been found, these rings could be collected for fifty rings each, allowing the characters to easily tap into the power of the Chaos Emeralds (usually becoming Super, or Hyper in Sonic 3 & Knuckles if the player has collected all the Super Emeralds as well). In most of the newer games since Sonic Adventure 2, these giant rings have taken the place of the old signposts as the end level marker and touching it would end the level.

- Main article: Chaos Emeralds
The Chaos Emeralds are seven emeralds with mystical powers, and a recurring feature of Sonic games. They are the basic of most of the games' plots, and the player is frequently required to collect them all in order to fully defeat Eggman and achieve the games' "good endings", super forms, or both. The method used to acquire the Emeralds differs between titles in the series. Most early games require the player to find them in Special Stages. In some games, such as Sonic R and the 8-bit versions of Sonic the Hedgehog and Sonic the Hedgehog 2, they can be found in hidden locations within the main levels. In most later games, the Chaos Emeralds are found by the characters throughout the games' story modes, and do not need to be "found" by the player.
- Main article: Master Emerald
The Master Emerald resides in a shrine on Angel Island and is guarded by Knuckles the Echidna; it contains an infinite amount of power, much greater than all 7 Chaos Emeralds, and is used to keep the Angel Island afloat in the sky. The Emerald also has the power to fully control everything that the Chaos Emeralds do, including the ability to negate the energy of the Chaos Emeralds, as seen in Sonic Adventure and Sonic Adventure 2, or empower them, as seen in Sonic the Hedgehog 3 & Knuckles. The Master Emerald can also be used to power mechanical devices, and has been coveted by Dr. Robotnik since his discovery of it. During Knuckles' final boss fight in Sonic the Hedgehog 3 & Knuckles, Metal Sonic powers up using the Master Emerald into a Hyper form.
- Main article: Special Stage
Usually, a Chaos Emerald may be earned in a Special Stage or Special Zone. Special Stages usually take place in surreal environments and feature alternate gameplay mechanics to the standard platforming of the main levels: the 16-bit Sonic the Hedgehog consisted of a giant rotating maze (which many considered a major technical achievement); Sonic the Hedgehog 2, Sonic 3-D Blast, Sonic Heroes and Sonic Rush featured "in your face" segments with the hedgehog running along a long tunnel, with a variant of this used for Knuckles Chaotix, Sonic Advance, and Sonic Advance 3; 3-D "collect items" levels, as in Sonic 3 and Sonic & Knuckles, which used the same perspective but had Sonic collecting all the blue-colored orbs on the surface of a giant sphere, and a different version, the 3-D ring-collecting Special Stage, used in Sonic Advance 2. Sonic Chaos (Sonic and Tails in Japan) utilized a variety of gimmicks for its levels.
Some Sonic titles include Special Stages, but not as a means of collecting Chaos Emeralds. As the Emeralds of the 8-bit version of Sonic the Hedgehog were hidden in the main stages, the game's spring-filled Special Stages were merely used as a means of adding variety, and for a player to increase their score. Similarly, Sonic 3 and Sonic & Knuckles, in addition to their main Special Stages, featured entirely optional bonus stages, one of which combined the rotating maze of the 16-bit Sonic the Hedgehog with the pinball gambling of Sonic the Hedgehog 2, and Sonic Heroes had an alternate Special Stage for earning lots of 1-UPS, very much like the one in which Chaos Emeralds are collected, but with the objective being to get to the Goal Ring before time ran out, rather than catching up to the Chaos Emerald at the end of the tunnel.
Just as the design of the Special Stages has changed, so has the means of accessing them. In Sonic 3 & Knuckles, giant rings were hidden in levels to take the player to the Stages, but most other titles involve the collection of a certain number of rings, usually 50. In both the 8- and 16-bit versions of Sonic the Hedgehog, they were reached by finishing a level with more than 50 rings; the player would then have to jump inside the giant ring that would appear just after the goal post. In the 16-bit Sonic the Hedgehog 2, reaching a Star Post when they held this number would create a warp of stars which would take a player to the Special Stage when jumped through. Sonic 3D required the player to deliver rings to Knuckles and Tails, who could be found within each level. Sonic Chaos changed the figure, with access to a Special Stage being the reward for collecting 100 rings.
In the more recent game Sonic Heroes, the Special Stages made a return. These special stages were accessed by finding a key in stage 2 of each zone and keeping it (by not taking damage) until the end of the level. It consisted of running through a twisting tube. The Chaos Emerald would be ahead of the characters, and the goal was to "catch up" with it by collecting orbs which refueled a "dash gauge" which the characters would use to speed up and catch it. The stages had some motion glitches which would sometimes cause the characters to slow down dramatically, making it difficult to complete the stage. If the Chaos Emerald got to the end of the stage before the characters caught up with it, the stage would end without the gaining of a Chaos Emerald.
Super Sonic's ending in Sonic and Knuckles - he will eventually become Sonic as he runs out of energy:Main article: Super transformation Since the 16-bit version of Sonic 2, Sonic has had the ability to transform into the extremely fast and nearly invulnerable Super Sonic once all seven Chaos Emeralds are collected. After that, Super Sonic can be used in any of the following levels once 50 rings have been collected, although one ring is lost for every second Sonic remains in this form.
In the Sonic Adventure titles, the Special Stages were omitted entirely and Chaos Emeralds were collected in non-interactive cut-scenes as part of the story, with Super Sonic only appearing in the climactic final boss fights. This dismayed many fans, who appreciated the additional replay value offered by retrying a game's levels with Super Sonic's additional abilities. Despite several games since returning to the emerald-collecting of the 2D platform titles (including the Advance series, Heroes, and Rush), Super Sonic was again only playable at the end of the game in an extra zone.
In Sonic Riders, Super Sonic is also an unlockable character, playable outside the final level for the first time since the Sega Genesis games. As with previous games, Super Sonic consumes rings as long as the form is sustained, and Sonic reverts to standard Sonic when he runs out of rings. He is playable by unlocking the "Chaos Emerald" gear. This mode of play is very difficult to play, however, due to the use of Rings as "air" in the game. Using the air features would deplete Sonic's Ring count at an accelerated rate, often leaving Sonic to run on foot until he could get more Rings to resume his Super form.
Other characters have also been able to utilize the Super transformation. In Sonic & Knuckles, Knuckles the Echidna could also transform into Super Knuckles. By locking-on Sonic 3 to Sonic & Knuckles, Hyper Sonic, Super Tails and Hyper Knuckles also become available, by collecting all 7 Super Emeralds in addition to the 7 Chaos Emeralds. In Sonic Adventure 2, Super Shadow also appeared at the end of the Last story, who fought alongside Super Sonic to destroy the Biolizard. In Sonic Rush, Burning Blaze appears for the extra boss, similar to the end of Sonic Adventure 2. It is named "Burning" instead of "Super" as she uses the Sol Emeralds instead of the Chaos Emeralds. In Sonic the Hedgehog, Super Silver appears along with Super Sonic and Super Shadow.
A feature unique to Sonic is his ability to use Super transformations using different sources of power other than the Chaos Emeralds, each with its own unique abilities. For Sonic and the Secret Rings, Sonic used the World Rings to become Darkspine Sonic. In Sonic Unleashed, Sonic had the ability to turn into Sonic the Werehog from the power of Dark Gaia. In Sonic and the Black Knight, Sonic transforms into Excalibur-Sonic using the power of the sacred swords.
The music of the Sonic series is considered one of the aspects that make the series popular. Sonic games have featured tunes composed by a variety of people; Masato Nakamura of J-pop band Dreams Come True was responsible for the music of the first two 16-bit games. Ys/Streets of Rage composer Yuzo Koshiro composed the music for the first 8-bit title, barring what was taken from the 16-bit title. Sega's in-house music company, Wavemaster, did the majority of the music in later titles. One Wave Master employee, Jun Senoue, is part of the band Crush 40, and through his ties to the band they have played the main theme tunes of the two Sonic Adventure games, Sonic Heroes, and Shadow the Hedgehog. Heroes and Shadow the Hedgehog also featured other bands, such as Julien-K. Richard Jacques, a frequent composer of music for Sega's games, contributed to the soundtracks of Sonic R and the Saturn/PC version of Sonic 3D Blast: Flickies' Island.

Sonic the Hedgehog 4 Episode 1
Since Sonic's first appearance in 1991, many more characters have appeared, and most of them have been added to main cast. Many of these characters have garnered steady fanbases since their inclusion into the franchise, while other longtime fans have criticized them for allegedly taking the gameplay focus off Sonic. Here are the main characters arranged in order of appearance:
|The series' principal hero. Sonic possesses incredible super speed and numerous other abilities, and uses his skills to save the world from Dr. Robotnik. He is impatient, laidback, confident and always on the look-out for an adventure.|||
|Dr. Eggman||Also known as Dr. Robotnik, Eggman is Sonic's arch nemesis and the series' main villain. He is extremely intelligent, pompous, egg-shaped, and has black eyes with red pupils, and a giant red-brown mustache. Eggman is an expert in robotics and wishes to conquer the world and build the Eggman Empire. However, Sonic and his friends always stand in his way. In many cases, his own plans ironically out do himself.|||
|Miles "Tails" Prower||Sonic's best friend. He is a two-tailed fox who can fly for a limited time by spinning his tails rapidly. He is a skilled mechanic and often takes care of Sonic's plane called the Tornado. He pilots a machine called the Cyclone, which is an upgraded version of the Tornado with battle-mech capabilities.|||
|Amy Rose||A pink hedgehog who has become Sonic's self-appointed girlfriend, first seen in Sonic the Hedgehog CD. Ever since Sonic and Amy met, she has been in love with Sonic and she now wants him to marry her. Amy is quite strong and smashes enemy forces down with her trusty Piko Piko Hammer.|||
|Metal Sonic||The robotic counterpart of Sonic the Hedgehog, who is created by Dr. Robotnik. He seems to believe that he is in fact the true Sonic, and that Sonic is his copy. In Sonic Heroes he betrayed his creator, and took the task of trying to achieve world domination into his own claws.|||
|Knuckles the Echidna||The last living echidna, and Sonic's hotheaded friend and rival. Knuckles resides on Angel Island, where he guards the Master Emerald, the source of the island's ability to float in the sky. Knuckles is very strong; his spiked fists are capable of smashing through boulders as well as allowing him to climb walls. The nature of his echidna spikes allows him to glide in the air for periods of time.|||
|Chaotix||A team of misfits who have started their own detective agency. The Chaotix consists of Vector the Crocodile, Espio the Chameleon and Charmy Bee. They met for the first time when they fought against Dr. Robotnik in Knuckles Chaotix, along with Mighty the Armadillo.|||
|Big the Cat||A big purple tabby cat who loves fishing. His best friend is a frog named Froggy, who he constantly keeps losing. Big lives with his buddy in a peaceful hut in the Mystic Ruins.|||
|E-102 Gamma||A robot created by Dr. Robotnik. Originally a part of the E-Series, he, thanks to Amy Rose, became good spirited and decided to save his friends. In the end, he destroyed himself to free a little bird that was inside of him so it could be with its family.|||
|Shadow the Hedgehog||Shadow is a mysterious, black hedgehog resembling Sonic in appearance and skills. He is the Ultimate Life Form created by Gerald Robotnik with Black Doom's DNA on the Space Colony ARK over five decades ago. He recently suffered from amnesia but has regained all of his memories since. He can use Chaos Control to distort time and space.|||
|Rouge the Bat||Rouge is a treasure hunter and a spy for GUN. She is full of feminine charm and can be very manipulative. She is Knuckles' rival.|||
|Cream the Rabbit||A naive young rabbit who lives with her mother, Vanilla. Cream's best friend is a Chao called Cheese (which she uses as missile). Because Cream has been brought up like a princess, she does not like being involved in other peoples' affairs. She can fly using her large ears.|||
|E-123 Omega||An robot created by Dr. Robotnik. He is the last of the E-100 series of robots and seeks revenge on Robotnik for shutting him down. Rouge accidentally activated him when trying to free Shadow from Robotnik's base. Since then, he has became good friends with both of them.|||
|Blaze the Cat||A female, pyrokinetic, lavender cat from a parallel universe. As guardian of the Sol Emeralds, it is her duty to prevent anyone from taking them away from her. She is somewhat shy, and tends to conceal her real feelings.|||
|Silver the Hedgehog||A mysterious platinum hedgehog from the future. Silver traveled through time to stop Sonic, who he believed to be the Iblis Trigger. Unlike Sonic, he utilizes psychic powers.|||
|Babylon Rogues||A group of Extreme Gear riders that search for treasures. The leader is Jet the Hawk and Wave the Swallow and Storm the Albatross follow him.|||
To create distinctive Sonic products in various markets, Sega initially developed two different back-stories for the instruction booklets; the Japanese version (which is considered the "true" canon by most fans), and the version for all other regions, which was the version built upon by the comics, cartoons, and other media. (This version was retconned in 1999, when Sonic Adventure came out, which continued the Japanese storyline in all regions.)
Differences between regional storylines include the setting of the game (while the non-Japanese version had the game set on a fictional planet called Mobius, the Japanese version had the games set on Earth from the very beginning), as well as Dr. Eggman's name, which was Dr. Robotnik in the American version. (Although now, Robotnik is his official last name while Eggman is a nickname made up by Sonic and his friends for him which he has since adopted and is hardly ever referred to as Robotnik anymore.)
Notification: This chronology is extremely speculative and in no way official; it is compiled by fans using best-guess reasoning. Feel free to discuss disputes and suggest revisions on the Talk page.
This is where the Sonic Series begins. It mostly involves Sonic being the only one to save the World from the Evil Doctor Eggman.
- Sonic the Hedgehog - (Genesis) (1991)
- Sonic 1 is the first game in the series and establishes the canon's foundation. It introduces the protagonist, Sonic, a 10-year-old hedgehog; the antagonist, Dr. Ivo Robotnik, a malevolent human scientist; basic gameplay elements; and bosses that have reappeared in later games, such as in Sonic Advance.
- Sonic the Hedgehog (8-bit) - (Game Gear, Master System) (1991)
- The Game Gear and the Master System both featured this game, although each one was very slightly different. As far as the story goes, Sonic is again saving the world from Dr. Robotnik.
- SegaSonic the Hedgehog - (Arcade) (1993)
- Seeing as how this game does not feature Tails, yet was released after Sonic the Hedgehog 2 for the Sega Genesis, this would theoretically be placed at the end of the list of games where Sonic fights without Tails; however, this game was released before Sonic CD and therefore takes place before it as well. This game also features the debut of Mighty the Armadillo and Ray the Flying Squirrel.
- Sonic the Hedgehog CD - (Sega CD) (1993)
- The placement of the game is in debate, due to conflicting storyline descriptions between the game's manual in U.S. release and the manual in the Japan release. The most important factor that would determine where this game takes place in the timeline is whether or not that Sonic has yet met Tails, but this is unfortunately were the conflict between the manuals is centered. Also, while Sonic CD was released after Sonic the Hedgehog 2 for both the Sega Genesis and the Sega Game Gear, Sonic CD was in production alongside the other two games and could have possibly been intended to come out before hand. Sonic CD takes place either after Sonic the Hedgehog 8-bit release, or after Sonic the Hedgehog 3 and Sonic & Knuckles, with the former being used here. This game includes the first appearances of Amy Rose and Metal Sonic.
- Sonic Labyrinth - (Game Gear) (1995)
- Like Sonic the Hedgehog CD, there is debate over where this game fits into the storyline due to the differences between the original storylines in U.S. and Japan. Because this game came out recently after Tails Adventure, this game can be placed in the timeline during the events of Tails Adventure, as per the U.S. storyline when the two split up. This timeline will assume that the Japanese storyline is the correct one, where the game takes place before Sonic met Tails.
This Saga mostly involves Miles "Tails" Prower being the hero and leads Tails to meeting Sonic.
- Tails' Skypatrol - (Game Gear) (1995)
- Because of the original intention of Tails not yet have meeting Sonic in Tails Adventure, and because this game came out before Tails Adventure, this game takes place before the events of Sonic the Hedgehog 2 for the Sega Game Gear. It can either take place during the events of “Meet Sonic the Hedgehog” or after and before “Sonic and Tails Together".
- Tails Adventure - (Game Gear) (1995)
- Although the Western story states that Tails split up from Sonic for a while, the Japanese story states that, during the events of this game, Tails has not yet met Sonic. Assuming that the Japanese story is the case, it can be included in “Meet Miles ‘Tails’ Prower”.
This Saga mostly involves Sonic and Tails working together to defeat Doctor Eggman.
- Sonic the Hedgehog 2 (8-bit) - (Game Gear, Master System) (1992)
- The story states that Tails gets kidnapped by Dr. Robotnik. After this game, Tails fights alongside with Sonic, so it can be assumed that this game marks the beginning of Sonic training Tails to fight for himself. The instruction manual indicated that Sonic 1 was the first fight against Robotnik, however, it can be assumed that this is meant to be a reference to Sonic 1 on the Game Gear. The manual also states that Sonic left after Robotnik's last defeat in search of adventure. This probably means that Sonic did not leave Tails right after meeting him and that they enjoyed peace for a while before Sonic got bored and left. It may also mean that, while in search of adventure, Sonic met Tails for the first time. Additionally, Silver Sonic (or a prototype of Silver Sonic) is introduced in this game.
- Sonic Chaos - (Game Gear, Master System) (1993)
- "Here he comes, straight from his high-speed Sonic 2 adventure! Headstrong Sonic The Hedgehog and his feisty friend Tails blast into hyperspeed to save the Chaos Emeralds. If evil Dr. Robotnik snatches the Emeralds first, he'll make a Super bomb! Could this be the end?" (Probably taken from instruction manual) The storyline to Sonic Chaos, like most Sonic stories, revolves around Dr. Robotnik and his quest for world domination via the use of the mysterious Chaos Emeralds to create nuclear weapons and lasers. (According to the U.S. version of the instructional manual)
- BONUS GAME - Sonic Drift - (Game Gear) (1994)
- This game is a racing game that includes Sonic the Hedgehog, Miles “Tails” Prower, Amy Rose, and Dr. Ivo Robotnik. Seeing as how this game does not include any story, it can be seen as pure filler. Although this game was released between Sonic the Hedgehog 3 and Sonic and Knuckles, and because both of those games are also considered one whole game, Sonic drift, if it would fit in the timeline at all, would go right before or right after. Because Knuckles is not featured in the game, it can be assumed that it takes place right before the events of Sonic the Hedgehog 3.
- Sonic the Hedgehog's Gameworld - (Sega Pico) (1994)
- "A Chaos Emerald has been hidden on each floor of Dr. Eggman's 5-story Gameworld, an amusement center built - like everything else he constructs - in his own mustachioed image. Sonic, Tails, and Amy must clear all the minigames on each floor and find the Emeralds." (Story taken from http://www.theghz.com/sonic/gameworld/gameworld.html)
- Sonic the Hedgehog 2 - (Genesis) (1992)
- It is interesting to note that the back story of Sonic the Hedgehog 4 mentions that this game seems to lead into Sonic the Hedgehog 3, but it is also interesting that it also mentioned that there was peace between this game and the first game. It is currently unknown whether or not the placement of the other games have changed because of this. Sonic Chaos is said to take place right(?) after Sonic 2, but that can be referring to the 8-bit version, since both Sonic 2 and Sonic Chaos are for the Sega Game Gear and Sega Master System. The instruction booklet indicates that Sonic 2 comes one year after the events of Sonic 1. The game features new sprites for Sonic who appears to be slightly older (he is now 11), and also introduces Tails (who is only four), Sonic's sidekick. Super Sonic makes his first appearance. Additionally, Silver Sonic (or the one after the prototype) is (re)introduced in this game. Due to Sonic Adventure DX showing 3 robot sonics, we can assume that it is the same Silver Sonic. The other two were Mecha Sonic and Metal Sonic. (It is interesting to not that the back story in Sonic the Hedgehog 4 refers to Silver Sonic as Mecha Sonic. For the sake of telling the difference between this robotic Sonic and the one from Sonic and Knuckles, this guide will refer to this robotic duplicate as Silver Sonic until further notice.
This Saga introduces Knuckles the Echidna.
- Sonic 3 and Knuckles comes soon after the events of Sonic 2 and recycles its sprites and game engine core. Inside the game, Sonic's story happens first, then Knuckles' story. In Sonic's story, Angel Island is in the sea and Knuckles is his enemy; in Knuckles' story, Angel Island is floating in the sky and Sonic is his ally. Additionally, this game introduces Mecha Sonic (not Metal Sonic).
- Sonic the Hedgehog: Triple Trouble - (Game Gear) (1994)
- The US Instruction manual tells us that, as usual Dr. Robotnik has captured all of the Chaos Emeralds. Unfortunately for him, an accident in the testing phase of his new ultimate weapon, the Atomic Destroyer, scatters the Emeralds back across the island. While Sonic and Tails are out to retrieve them, they are cut short by Knuckles the Echidna. Robotnik has already reclaimed the yellow emerald, and he's once again duped the Guardian into believing Sonic and Tails are out to steal the stones. Meanwhile, a sneaky treasure hunter named Nack the Weasel (Fang the Sniper in the Japanese version) is taking advantage of the commotion to collect the Emeralds himself. He does not know of the true power of the Emeralds, but he does know the large, pretty gems would fetch a high price. Now it's a mad four-sided race for the Chaos Emeralds. Additionally, Metal Sonic makes its second appearance since Sonic CD as a boss near the end of the game.
- Knuckles' Chaotix - (32x) (1995)
- Introduces Vector the Crocodile, Charmy Bee, Espio the Chameleon, Mighty the Armadillo, Heavy, and Bomb. Additionally, Metal Sonic makes its third appearance in this game where it goes under a type of transformation in which it grows huge and is red. It also has a large laser cannon on its chest and tries to crush the player with its large hands. Prior to the fight, Metal Sonic is seen going with Dr. Robotnik into a ring, and then this Metal Sonic appears. It is often times known amongst fans as Super Metal Sonic or Mega Metal Sonic. In the end, it is defeated.
- BONUS GAME - Sonic Drift 2 - (Game Gear) (1995)
- This is another racing game that is most likely pure filler due to the lack of a story. It added three new playable characters, Knuckles the Echidna, Fang the Sniper/Nack the Weasel, and Metal Sonic. The only thing close to a story is the fact that in the game, Chaos Emeralds are awarded for winning races. If Sonic, Tails, Knuckles, or Amy collect all six in the Blue GP, they will face Dr. Eggman in a final race around the Death Egg. If Eggman, Metal Sonic, or Fang collect all six in the Blue GP, they will face Sonic in the final race.
- Sonic the Fighters - (Arcade) (1996)
- Dr. Robotnik has built the Death Egg II, and it is up to the heroes to foil his Death Egg plans once and for all. Introduces Bark the Polarbear and Bean the Dynamite. Metal Sonic makes its fourth appearance in this game as the second to last fighter before facing Dr. Eggman. There is a new type of Metal Sonic only seen in the opening sequence of this game known as Mecha Sonic Model No.29, but by playing as it through a hack, the name is known as RocketMetal.
This is just another Saga of Doctor Eggman hatching different evil plots to take over the World.
- Sonic 3D Blast - (Mega Drive, Genesis) (1996)
- Dr. Robotnik discovers Flicky Island and its inhabitants, the Flickies. He plans on using them and their ability to travel anywhere via large rings by turning them into robots to help him search for the Chaos Emeralds.
- Sonic Blast - (Game Gear) (1996)
- While this game was released at the end of 1996 in conjunction with the similarly named Sonic 3D Blast, it is worth noting that both games have little in common. No enemies, levels, or bosses, are shared between the games. The story is also completely different. Sonic and Knuckles join together to collect five of the Chaos Emeralds and confront Eggman at Silver Castle. (See source for details)
- Sonic R - (Saturn) (1997)
- "This race is unlike any other in the Sonic Universe in that this World Grand Prix race takes place on foot! Sonic joins the race once he discovers his nemesis is using the race as an excuse to get to the Chaos Emeralds. Knuckles and Amy join in to wreak havoc on Dr. Eggman’s plans as well" (This information was taken from http://www2.sega.com/sonic//content.php). The game featured a few new characters to the series - Metal Knuckles and Tails Doll, who never again made an appearance, except for a target practice dummy of tails which looked like Tails Doll in Sonic Adventure DX. Additionally, Egg Robo, a robot version of Dr. Robotnik from Sonic and Knuckles, was a playable character as well.
- Sonic the Hedgehog Pocket Adventure - (Neo Geo Pocket Color) (1999)
- The reason for this being placed here is, perhaps not necessarily due to the lack of characters, but due to one important factor-Dr. Eggman changes from his old outfit to his new outfit by the end of the game. Additionally, Silver Sonic makes another appearance (as a boss) since Sonic the Hedgehog 2 (16-bit) chronologically, unless the Silver Sonic from Sonic the Hedgehog 2 (16-bit) is actually the same Silver Sonic from Sonic the Hedgehog 2 (8-bit) for the Sega Game Gear. If that was the case, then this would mark its third appearance.
- Sonic the Hedgehog 4 - (Wii, PS3, Xbox 360) (2010)
- Although it is said to be a direct sequel to Sonic & Knuckles, there is one main reason that places this game so far ahead, and that is Dr. Robotnik's costume change. At the end of Sonic the Hedgehog Pocket Adventure, Dr. Robotnik changes into a different outfit, but after that, he keeps that outfit throughout the rest of the series. Since the game has not yet been released, this placement may change, but it is not unreasonable to be placed this far after Sonic & Knuckles, since the other numbered games (1 through 3) have other titles in between them.
This is the Saga where most of the Characters get redesigned and where Amy joins the Fight against Eggman. The last game of this Saga, "Sonic Adventure 2," introduces Shadow the Hedgehog and Rouge the Bat.
- Sonic Advance - (GBA) (2001)
- While some may assume Sonic Adventure comes first, Sonic Advance comes first for two clear reasons: (1) Sonic's red Tornado biplane appears in it, but it was shot down and destroyed in Sonic Adventure; (2) In all the games after this game, including Sonic Adventure, Dr. Robotnik has a much more complicated way of taking over the world, but in Sonic Advance 1 and 2, Robotnik has the same old scheme: keep Sonic distracted with his robots while he tracks down the Chaos Emeralds.
- Sonic Advance 2 - (GBA) (2002)
- There are three reasons why Sonic Advance 2 occurs here. It is evident from the game and official material that Sonic Advance 2 closely follows its prequel. In Sonic Adventure's GameCube remake, Cream has a cameo appearance when she gives Sonic the Ice Stone, whom she met in this game. The third reason is that Robotnik's strategy is essentially unchanged from Sonic Advance.
- Sonic Adventure - (Dreamcast) (1998)
- Adventure marks the first of the fully 3-D and evolved Sonic games. Sonic Adventure is closely connected to Sonic & Knuckles, as seen by the fall of Angel Island. It also makes several references to earlier games: Sonic making jokes at Knuckles' expense about his history with Robotnik (now called Eggman); Tails' dream of when he first met Sonic; and Amy's flashback of when Sonic first rescued her from Eggman's base on the Little Planet while being chased by Metal Sonic.
- Sonic Shuffle - (Dreamcast) (2000)
- The story involves Sonic and company getting caught up in a mess in a world called Maginary World, which they inadvertently stumble upon one day. A villain named Void has shattered the Master Precioustone into many pieces, resulting in chaos in every part of the world. Lumina Flowlight and the rest of Maginary World are counting on Sonic to restore it and bring Illumina back, who mysteriously disappeared after the disappearance of the Precioustone. (See source for details)
- Sonic Adventure 2 - (Dreamcast) (2001)
- It is Sonic Adventure's sequel, and the events within closely follows it's prequel. This game introduces Shadow the Hedgehog, a doppelganger of Sonic, and Rouge the Bat, a rival treasure hunter for Knuckles.
This Saga includes the games that Cream is involved in. This Saga also marks the Return of the Chaotix and Shadow the Hedgehog himself after his apparent death.
- Sonic Heroes - (GameCube, PS2, Xbox, PC) (2003, 2004)
- It continues 5 months after the storyline of Sonic Adventure 2. The game stars Metal Sonic as the antagonist of the game instead of Dr. Eggman. In Team Dark's story, Shadow begins his story inside a cryogenic capsule; Rouge is surprised that he is still alive. In Team Rose's story, Amy begins her story relaxing at the beach in a scene reminiscent of the opening cut-scene of Sonic's story in Adventure.
- BONUS GAME - Sonic Pinball Party - (GBA) (2003)
- The story for this possible bonus game is set in Casinopolis (in Station Square), where Doctor Eggman turns the people gambling into robots, and brainwashes Miles "Tails" Prower and Amy Rose. Sonic must rescue his friends by winning a pinball tournament called the "Egg Cup Tournament." (See source for details.) Also, even though Cream was introduced in Sonic Advance 2 and Sonic Adventure DX, it is because they came out later on than when they were actually placed in the timeline. At this point, Cream becomes a recurring ally. Though this game may not be Canon since its a Spin-off and it does include Sega Crossover Characters Nights and Amigo.
- Shadow the Hedgehog - (GameCube, PS2, Xbox) (2005)
- It makes several references to Sonic Heroes, and, in Sonic Battle, Shadow is completely aware of his past and rants on about trusting in Maria, but in this game, he can only remember one tidbit of his memory, and, he doesn't even know who Maria is. "And who is this 'Maria'?" - Shadow the Hedgehog
- Sonic Battle - (GBA) (2003)
- Even though this game was released before Sonic Heroes, it comes after, because Rouge comments about E-102 Chaos Gamma (who she believes to be a Guard Robo) looking like Omega, whom she met in Sonic Heroes. "...that Guard Robo looked just like Omega" - Rouge the Bat. The second reason was explained above, in the case with Shadow's past.
- Sonic Advance 3 - (GBA) (2004)
- It is seen that this game closely follows Sonic Battle, and it continues Battles storyline, seeing as Eggman found Emerl's pieces and re-built him into G-mel. Emerl is a robot introduced in Sonic Battle.
This Saga introduces Silver the Hedgehog and Blaze the Cat and yet they're only involved in the games of this Saga. Both Silver and Blaze appeared in Sonic the Hedgehog 2006 and they appeared in separate Handheld series with Silver in the Sonic Rivals Games and Blaze in the Sonic Rush Games. Eggman Nega was also introduced in this Saga as the Main Villain of the Sonic Rivals Games and the Sonic Rush Games.
- Sonic the Hedgehog - (Xbox 360) (2006) (PS3) (2007)
- The placement of this game in the timeline is debatable. Although Blaze seemingly recognizes Sonic when she utters "Blue Hedgehog..." (whom she first met in Rush), in the end of this game, Blaze is sealed away into another dimension. This could possibly be the dimension that Blaze lives in in "Sonic Rush". Although this game seems to retcon itself by erasing the events of the game from history, Blaze is not seen in the end when the past, present, and future merge. Therefore, Blaze and the future Iblis sealed inside of her have been sent away from the timeline, resulting in her own existence being erased from her home world/dimension. Additionally, Silver the Hedgehog is introduced in this game.
- Sonic Rivals - (PSP) (2006)
- In this game, Eggman Nega turns out to be the main antagonist of the game who hails from the future. Masquerading as Dr. Eggman in the past, he uses a special camera to turn everyone into cards on Onyx Island, an island he brought along with him from the future. His master plan is to change his destiny by turning the whole planet into a card that he can control. It is revealed that he was never an alter ego, but a descendant of Eggman. Additionally, Silver the Hedgehog makes a reappearance in this game. Due to that fact that Eggman Nega turns against Eggman (and with the discovery that he is a descendant and not an alter ego), this takes place before the Sonic Rush games, where Eggman Nega thinks less of Dr. Eggman, his ancestor. Once sealed away into another dimension, he presumably decides to ally himself with Dr. Eggman when given the opportunity.
- Sonic Rivals 2 - (PSP) (2007)
- This game introduces Metal Sonic version 3.0, which is a robot built by Eggman Nega. Because Dr. Eggman is not the main antagonist of the game, he sends Metal Sonic as to help fight against the threat of Eggman Nega. Silver again makes another appearance in this game. Since the game is closely tied to its prequel, it takes place after it.
- Sonic Rush - (DS) (2005)
- It has to happen after Sonic Advance 3, because several elements introduced in Advance 3 are re-used in this game, such as Cream's house and the new looking Flickies. Blaze the Cat is introduced. This game has to take place after Sonic Rivals 2 due to the fact that Eggman Nega has been most likely sealed away in the same dimension as Blaze. Blaze not recognizing Sonic must be a side effect of being sealed away, and, since the events during the time of her being sealed away were erased from her original world, it is possible that she too was somehow still affected.
- Sonic Rush Adventure - (DS) (2007)
- It's most likely that this game comes next due to the fact that Dr. Eggman and Eggman Nega still have a working relationship, as the Sonic Rivals series shows that Eggman Nega develops a tendency to work alone or dispose of Eggman first.
This Saga mostly involves the Sonic Riders Games and the Babylon Rouges: Jet, Wave, and Storm.
- Sonic Riders - (GCN, PS2, Xbox, PC) (2006)
- This game introduces the Babylon Rouges-Jet the Hawk, Wave the Swallow, and Storm the Albatross-as well as the E-10000 series. Jet and Sonic seem to have a rivaling relationship over who is the fastest thing alive, and, in the end, Babylon Garden's secret treasure is uncovered after defeating the Babylon Guardian. The reason this game takes place after Saga 8 is because, even though some of the games from the previous saga were made after Sonic Riders, others were made before it; however, those games go together as a whole saga. Sonic Riders can take place before Saga 8, but it can also lead into Sonic Riders: Zero Gravity. Therefore, the placement of Sonic Riders and Sonic Riders: Zero Gravity is not definite, but Sonic Riders: Zero Gravity does have the newer characters from those games developed later on as secret characters (such as Blaze and Silver).
- Sonic Riders: Zero Gravity - (Wii, PS2) (2008)
- The game closely follows Sonic Riders, and it continues the story of the Babylon Rouges. Like Sonic Riders, this game's chronological placement can also be before Saga 8, but only as long as this game's secret characters from the newer games do not interfere with the canon of the story. Other than that, it was developed and made after most of (if not all of) the games from the previous saga. Therefore, this game really can take place in this saga. Sonic Riders may or may not lead directly into this game, but Sonic is still carrying his board in this game, so it can be assumed that it does.
So far this Saga only has one game and this game could be out of continuity; given the appearance of the Tornado mk. I, the fact that the only companions present are Tails and Amy, and that at the end of Sonic Unleashed the world is essentially returned to normal, this could possibly take place at a much earlier point in the timeline.
- Sonic Unleashed - (Wii, PS2, PS3, Xbox 360) (2008)
- Before he can finish stop Dr. Eggman's evil plans once again, Super Sonic is engulfed by the dark energy of Dark Gaia, a creature that prematurely awakens from the center of the Earth and rips the world into several pieces. As a result, when the day turns to night, Sonic undergoes a transformation in which he becomes a Werehog. Eventually, Dark Gaia absorbs its dark energy that resides inside of Sonic, putting a stop to the Werehog transformation. In the end, Dark Gaia is defeated by Super Sonic and Light Gaia, and the world is restored to normal.
This Saga includes the Sonic Chronicles Series and this Saga also takes place 2 years after the previous Sagas.
- Sonic Chronicles: The Dark Brotherhood - (DS) (2008)
- Taking place at the end of the timeline for now, due to the fact that it leaves off on a cliffhanger, Sonic Chronicles: The Dark Brotherhood introduced a number of new characters as well as explains mysteries from the past. The story revolves around the Twilight Cage, a realm where powerful beings/races who threaten the peace of the world are sealed away by the god, Argus. Trapped in the realm, Sonic and friends save the day and escape, only to find their world taken over by Dr. Eggman due to the amount of time that passed by while they were trapped inside the Twilight Cage (since time moves slower in the Twilight Cage).
- Sonic Chronicles 2 - (DS) (TBA)
- This game will most likely pick up where Sonic Chronicles: The Dark Brotherhood left off.
This Saga includes the Sonic Storybook series.
- Sonic and the Secret Rings - (Wii) (2007)
- Sonic enters the world of Arabian Nights, a book that appears in front of him. He journeys to save the world of Arabian Nights, as well as his own life and his new friend, Shahra the Ring Genie, from the evil genie, Erazor Djinn, from the story of Aladin. In the end, Sonic and Erazor Djinn each use powers from the Seven World Rings and transform into Darkspine Sonic and Alf-Layla-wa-Layla respectively. Darkspine Sonic defeats Alf-Layla-wa-Layla, then they turn back to normal. Erazor Djinn is forever sealed away inside his lamp. The story is saved, and the name of the book changes from "Aladdin and the Magic Lamp" to "Sonic and the Secret Rings". Sonic then leaves the Arabian Nights.
- Sonic and the Black Knight - (Wii) (2009)
- Continuing from Sonic and the Secret Rings, Sonic enters the world of King Arthur to stop the Black Knight. Sonic is summoned by Merlina to save the Arthurian world from the reign of King Arthur, the Black Knight. By the end, they find out that King Arthur was an illusion conjured up by Merlina's grandfather, Merlin. Taking the Black Knight's Scabbard, Merlina planned to make the world eternal by using the power of the underworld. With the help of The Knights of the Roundtable (Sir Gawain, Sir Lancelot, and Sir Percival), and the Lady of the Lake, a barrier was formed around the castle to stop the spread of the underworld using the four legendary swords. Although the barrier was weak, Sonic jumped in with Caliburn, and fell to the Dark Queen-the now powerful Merlina with the Scabbard. After breaking Caliburn, the Dark Queen easily overpowers Sonic. His will to keep fighting returns the light to the sacred sword, revealing Caliburn to be Excalibur when the Lady of the Lake has Lancelot, Gawain, and Percival throw their swords-Lancelot's Arondight, Gawain's Galatin, and Percival's Laevatein-into a portal, which fuse with Caliburn and cover Sonic, ultimately transforming him into Excalibur-Sonic. In the end, the Dark Queen is defeated and Sonic is revealed to be the true King Arthur. Sonic then returns home to find an angry Amy, who doesn't believe Sonic upon him telling her about why he missed their date. Additionally, the name of the book changes from "King Arthur and the Knights of the Round Table" to "Sonic and the Black Knight".
- Sonic the Hedgehog Spinball - (Genesis, Master System, Game Gear) (1993)
- Dr. Robotnik takes control of Mount Mobius, turning it into his new Veg-O-Fortress, which transform helpless animals into robot slaves at an astounding rate. In the end, Sonic retrieves the Chaos Emeralds and takes down Dr. Robotnik once, again. It my or may not be set in the Archie Sonic the Hedgehog comic or SatAM cartoon due to the cameos, but they could be nothing more than simple cameos, since they only appear in bonus rounds.
- Blue Sphere – (Genesis) (1995)
- A collection of special stages from Sonic the Hedgehog 3 and Sonic & Knuckles. There are also some new stages. Made by combining Sonic and Knuckles with Sonic the Hedgehog(Genesis).
- Sonic Crackers – (canceled)
- Eggman traps Sonic and Tails together with a band of rings. It is not sure when this game would have taken place since it was canceled, but it was probably near the sixth saga since Eggman has already begun his complicated plans, starting with trapping our heroes in a band of rings.
- Sonic X–Treme – (canceled)
- Eggman is after the Rings of Order. Had this game not been canceled, it probably would have bridged the gap in between the fifth and sixth saga since Eggman has begun his complicated plans.
- Mario & Sonic at the Olympic Games – (Wii) (2007) (DS) (2007)
- This game lacks a story but it would have taken place somewhere after Saga 9. However, it is the first meeting between Sonic and Mario.
- Mario & Sonic at the Olympic Winter Games – (Wii, DS) (2009)
- This game would most likely occur after the events of the previous Olympics game due to the time difference. The first game takes place in 2008 while the second occurs in 2010, both years when the Olympics occurred.
- Super Smash Bros. Brawl – (Wii) (2008)
- This game's storyline is non–canonical to all characters that appear in it.
- SegaSonic Cosmo Fighter – (Arcade)
- Waku Waku Sonic Patrol Car – (Arcade) (1991)
- Various mobile phone games
- Sonic's Schoolhouse – (PC) (1998)
- Tails and the Music Maker – (Sega Pico) (1994)
- Tails teaches how to play music.
- Sonic Eraser – (Meganet / Mega Drive) (1991)

The Sonic video game franchise has led to a large number of spin-offs starring Sonic. Each spin-off incorporates aspects from the games to varying degrees.
Adventures of Sonic the Hedgehog (or AoStH for short) is an American animated television series that was first broadcast in September, 1993, and has been running in cartoon syndication ever since. It follows the escapades of Sonic and Tails as they stop the evil Dr. Ivo Robotnik and his array of vicious robots from taking over the planet Mobius. The plots very loosely followed the storyline of the video games series; at the time the Sonic games were still quite new, and lacking much plot or character development, which was in turn filled in by the show's writers.
The animated television series simply called Sonic the Hedgehog originally aired from September 1993 to June 1995. While Adventures of Sonic the Hedgehog is known for its bright colors and whimsical humor, Sonic the Hedgehog featured darker stories which constituted a departure from the tone of the Sonic games of the time. To distinguish between the two series, fans typically refer to this series as SatAM because it was a Saturday morning cartoon while Adventures of Sonic the Hedgehog aired on weekdays in syndication, and using the show's full title would cause confusion in many situations because the show's title is the same as the character's name.
A two-episode OVA film series based upon the game Sonic CD and the video game series as a whole, Sonic the Hedgehog: The Movie was made in Japan in 1996 and released as a dub in North America in 2000. Unlike the games, the film takes place on a world named Planet Freedom that, as with many anime series, appears to be a crossbreed of a fairytale land and Earth. At the time of its creation, the anime did not differ as far from official canon as it does today; at this point, it could be considered to take place in an a different continuity than the games, just like other versions of Sonic from other media.
The cartoon Sonic Underground ran for only one season, 1998 to 1999; it bears little relation to other entries featuring Sonic (including previous games, comics and animated series), and shares few established characters. 65 episodes were originally produced, and of those, only 40 were released. Unlike its predecessor, SatAM, the heroes do not remain in a sanctuary-like refuge but instead travel around Mobius to battle Robotnik's forces on a global scale. The Mobian civilization featured in the series includes multiple cities, a poor underclass and an aristocracy for the heroes to interact with. Sonic Underground is the only animated series based on Sonic where Tails has not made an appearance.
The anime Sonic X is the longest-running and most successful animated series based on Sonic to date. Originally planned as a 52 episode series that would be inspired by the story lines of the Sonic Adventure series, Sonic X has now expanded to 78 episodes with the latest 26 episodes set primarily in outer space. The series borrows more cast members from the games than any other Sonic cartoon before it; with the exception of Blaze the Cat, E-123 Omega, Babylon Rogues, Silver the Hedgehog, and Metal Sonic, every significant and playable video game character has made an appearance in the series. Sonic X is also the only animated series to include Super Sonic. Despite these similarities, it is not completely compatible with the video game canon if only for the fact that it shows Sonic being transported to Earth from another world; in the games, Sonic has always lived on Earth.
The Sonic the Hedgehog manga series, published in Shogakukan's Shogaku Yonensei (literally "fourth-year student") was written by Kenji Terada and it was illustrated by Sango Norimoto. The manga, which started in 1992, was about a hedgehog boy named Nicky who can turn into Sonic the Hedgehog. Sonic fights Dr. Robotnik, with Tails tagging along to help him.
Sonic the Comic, known to its many readers as STC, was a UK children's comic published by Fleetway Editions between 1993 and 2002. Although it was the UK's official Sega comic, Sonic the Comic established its identity and ongoing storyline and setting when Sonic, Tails and their friends were sent forward in time six months. During their absence, Doctor Robotnik successfully conquered the entire planet of Mobius, and Sonic's group were forced underground, operating as "freedom fighters" attempting to bring down Robotnik's rule of the planet. Due to an aggressive series of budget cuts on the part of Fleetway, the series went into full reprint by issue 184; the final story ended with a number of loose ends left untied. An online fan based comic, called STC-Online, has been set up to continue the STC story starting from where the original STC story left off and beginning with issue 224, due to STC being reprints from issues 185 to 223. It has received positive feedback from both fans and writers of the original STC.
Sonic the Hedgehog is an ongoing series of American comic books published by Archie Comics All of Archie's Sonic-related series, miniseries and specials take place in the same fictional universe. This universe features a mixture of characters, settings and situations from the video games, the SatAM cartoon, the various other incarnations of Sonic, and many elements unique to the comic universe. The current status quo of the comic deals with a full-scale war between the Eggman Empire, ruled by Robotnik, and the restored Kingdom of Acorn, currently ruled by King Elias Acorn.
Sonic X is the title of an ongoing comic book series that exists to supplement the stories from the animated series of the same name. It began in September 2005 and was originally meant to be a four-part series; due to the positive reaction to the series' announcement, it was extended to ongoing status before the first issue premiered. The comic is unique in that it is not directly based on the games; the comic is based on the television show and takes place in its expanded fictional universe. The comic borrows elements from the series first two seasons of the show, including Eggman's fort, destroyed in Season One on the cartoon, and characters from the Sonic Adventure storyline.
