They are the basis of many of the games' plots, and the player is frequently required to collect them all to fully defeat Dr. Eggman and achieve the games' "good endings", super forms, or both. The method used to acquire the Emeralds and the result in collecting them differs between titles in the series. Most early games require the player to find the emeralds in Special Stages. In some games, such as Sonic R and the 8-bit versions of Sonic the Hedgehog and Sonic the Hedgehog 2, the emeralds 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, (often through a cut scene) and do not need to be "found" by the player. The Chaos Emeralds have gone through various redesigns as the series evolved. At present they are no longer known as the octagonal shape that they were before, and have acquired a more traditional shape of a gem, specifically, brilliant cut. I wonder what will happen if the master emeraldIs added with them,I wonder?
In Sonic the Hedgehog 2, Sonic 3, Sonic & Knuckles and Sonic 3 & Knuckles, gathering all the Chaos Emeralds allows Sonic to turn into Super Sonic by collecting 50 rings and jumping in midair. In Sonic & Knuckles, Sonic 3 & Knuckles and Sonic the Hedgehog 2 featuring Knuckles the Echidna Knuckles can also transform into Super Knuckles. In Sonic 3 & Knuckles, players can obtain Super Emeralds, that enable the player to transform into Hyper Sonic, Hyper Knuckles and Super Tails.
Early Sonic games featured six emeralds, whilst the usual amount used is seven. There are eight in Sonic the Fighters , and numerous emeralds in Sonic Spinball.
There are various versions of the Chaos Emeralds in different media. For Sonic Rush, the Sol Emeralds are from the alternate dimension Blaze the Cat is from. They are almost identical to their Chaos counterparts, the only exception is that the Sol Emeralds have an emerald-cut design. In Adventures of Sonic the Hedgehog, there are four Chaos Emeralds of varying shapes, representing invisibility, invincibility, immortality and the power of life. Chaos Emeralds also appear in Sonic Underground, with an appearance similar to the Master Emerald shards of Sonic Adventure .
