The Chaos Drive^[1][2] (カオスドライブ^[3], Kaosu Doraibu^?) is an object that appears in the Sonic the Hedgehog series. It is crystallized Chaos Emerald energy that is usually contained in devices. They are a power source for various types of machines (such as the Eggwalker), and other devices, like the Dynamo Cage.^[4] The Chaos Drives were initially designed by Gerald Robotnik as a means of transferring energy to living tissue during Project Shadow.^[5] In the aftermath of this project, the Chaos Drives began being used by the Guardian Units of Nations to power their robots.^[6] Other factions, like the Eggman Empire, have been known to use these crystals for their machines as well.

Game appearances[]

Sonic Adventure 2[]

Chaos Drives first appeared in Sonic Adventure 2 under the name Chaos drives,^[7] where they served as power source for G.U.N. robots, much like how Animals are used for Badniks. Collected and used with Chao at Chao Gardens, they enhance a Chao's specific skills:

Image	Swim	Fly	Run	Power	Stamina	Mood
	+0	+0	+24	+0	0	+1
		+24	+0
		+0		+24
	+24			+0

With the right combination of animals, color of Chaos drives and depending on who is raising the specific Chao can alter the outcome of the Chao to appear similar to a character.

When playing as either Tails or Eggman, collecting Chaos drives in a stage also replenishes some HP.^[1]

Sonic the Hedgehog (2006)[]

The Chaos Drives appear once again in Sonic the Hedgehog (2006) along with Light Cores, both of which replenish differing amounts of energy to the Action Gauge (Chaos Drives restore the most). Incidentally, Chaos Drives also appear as the icon for the Gauge Up Item Box which fully restores the Action Gauge when collected. Unlike in Sonic Adventure 2, where Chaos Drives slowly fall to the ground for characters to pick up, Chaos Drives home onto the playable character the moment one of Eggman's robots are destroyed. They are not used for raising Chao, as Chao Gardens are not present in this game.
