Chaos Emerald
A Chaos Emerald is a powerful gem found in the Sonic the Hedgehog series. There are seven in all, along with the more powerful Master Emerald (which has not yet appeared in any Mario-related games), and comparable to the seven relics needed in Super Mario RPG: Legend of the Seven Stars and the Paper Mario series. Once all are gathered, they turn Sonic into Super Sonic.
In the Wii version of Mario & Sonic at the Olympic Games, the Chaos Emerald appears in Dream Race as an item that is most frequently obtained when the player is in fourth place. When used, the player becomes invincible and gains a speed boost, as well as stunning all of the other characters and causing them to lose speed. In the DS version, the Chaos Emerald appears in the Dream Basketball event, where it can be used to cause either the other characters' baskets to move faster or a Boo to block one of the baskets. In Dream Long Jump, the Chaos Emerald can be used to create a strong headwind that affects all of the players.
In the Super Smash Bros. series, the Chaos Emerald appears during Sonic's Final Smash, Super Sonic. Once the Smash Ball is broken open, the Chaos Emeralds instantly appear around Sonic, causing him to transform. Also in these games, the blue Chaos Emerald appears in one of Sonic's victory poses if he wins a match.
They appear once again in Mario & Sonic at the Olympic Winter Games in the Dream Figure Skating event. The players collect them over the course of Green Hill and Death Egg, eventually using all seven to defeat a reawakened Perfect Chaos.
Chaos Emeralds also appear as an item in Mario & Sonic at the London 2012 Olympic Games Party Mode. In this game, they stun opponents for a few seconds.
