The Chaos Emeralds are objects that appear in the Sonic the Hedgehog film series produced by Paramount Pictures and its spin-offs. They are seven mystical emeralds that possess powerful properties and abilities. Ages ago, they were fused together by the echidnas to create the Master Emerald, creating an object of ultimate power. Centuries later, the Chaos Emeralds returned when the Master Emerald was shattered, only to disappear after Sonic the Hedgehog used them to save the universe.
The Chaos Emeralds are seven brilliant cut gems in the colors green, red, blue, yellow, purple, turquoise, and white. In terms of size, they are rather small, each one easily fitting within the palm of a hand. Notably they were slightly bigger when the echidnas used them to create the Master Emerald, a little bigger than a closed fist.
Powers and traits
The Chaos Emeralds are extremely powerful relics; while it is unclear how powerful they are by themselves, when brought together, they create a source of ultimate power. Even without their gestalt form though, they hold enough power to turn a person into one of the most powerful beings in the universe.
The Chaos Emeralds' power can be accessed with or without physical contact. When all seven Chaos Emeralds are harnessed by living beings, they will bestow a person with a god-like state that grants flight, vastly increased innate talents, and the ability to turn thoughts into reality.
The Chaos Emeralds appear to respond to thoughts; after Sonic received comforting words of love in what he thought to be his final moments, the Chaos Emeralds reacted to Sonic's feelings, causing him to inadvertently absorb them and gain their power.
Ages ago, the seven Chaos Emeralds were acquired by the warriors of the echidna tribe, who forged them together to create an all-powerful object with the ability to turn thoughts into reality: the Master Emerald. However, believing no one should wield such power, the owls stole the Master Emerald from the echidnas and hid it away on Earth.
Sonic the Hedgehog 2
Centuries later, the Master Emerald was acquired by Dr. Robotnik, who used its power to begin his plans of conquest. During Sonic, Tails and Knuckles' battle to take it back, the Master Emerald crumbled and fell apart in an injured Sonic's hands, releasing the Chaos Emeralds. As Sonic, Tom and Maddie stood to be crushed by Robotnik's Giant Eggman Robot, the Chaos Emeralds responded to Sonic's feeling of love from Tom and Maddie, causing Sonic to inadvertently absorb them and transform into Super Sonic. With this power, Sonic saved his foster family and defeated Robotnik and his robot. After then using his powers to give himself and Knuckles chili dogs, Sonic released the Chaos Emeralds, having deemed himself not mature enough to wield their power, causing them to disappear to parts unknown.
