The Chaos Emeralds are seven relics, and collecting them all unleashes incredible power upon their wielder. One of them grants the ability to use "Chaos Control," a power that allows you to teleport anywhere. The Master Emerald is the relic guarded by Knuckles which has a power greater than that of the Chaos Emeralds allowing whoever uses it to destroy entire planets.
