Chaos Drive

For the Experience increasing gem in Sonic Unleashed, see Chaos Orb.

The Chaos Drive^[1] (カオスドライブ^[2], Kaosu Doraibu^?) is an object that appears in the Sonic the Hedgehog series. It is crystallized chaos energy that is usually contained in devices. They seem to be a power source for robots. The Chaos Drives were initially designed by Prof. Gerald Robotnik as a means of transferring energy to living tissue, as part of his work on Project Shadow.

Game appearances

Sonic Adventure 2

Chaos Drives first appear in Sonic Adventure 2 as power source for GUN Robots much like Animals are used for Badniks. Collected and used with Chao at Chao Gardens, they enhance a Chao's specific skills:

Color	Swim	Fly	Run	Power	mood
Green	+0	+0	+24	+0	+1
Purple	+0	+24	+0	+0	+1
Red	+0	+0	+0	+24	+1
Yellow	+24	+0	+0	+0	+1

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.

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.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, a Chaos Drive is revealed to be the power source of E-123 Omega.^[3]

Chao In Space

In the Chao in Space animated short, a Chao dreams of being given seven Chaos Drives which cause the Chao to form a golden cocoon and emerge in a super transformation, parodying the effect of the Chaos Emeralds on Sonic the Hedgehog.

Trivia

Sometimes, after going to Rouge's section in Shadow's version of Kingdom Valley, a Chaos Drive will glitch and become stuck in the ground.
