Chaos DrivesMedia:SonicAdventure2 DC US manual.pdf[1]Media:Sonic06 360 US manual.pdf[2] (カオスドライブMedia:SonicAdventure2 DC JP manual.pdf[3]Media:Sonic06 ps3 jp manual.pdf[4]) are collectible objects in the Sonic the Hedgehog series. These objects typically have the appearance of capsules with a coloured shard containing Chaos Emerald energy inside, and seem to act as a power source to robots. The Chaos Drives were initially designed by Professor Gerald Robotnik as a means of transferring energy to living tissue, as part of his work on Project Shadow.

Game appearances

Sonic Adventure 2

Sonic Adventure 2 is the first game to feature Chaos Drives, where they are used as a power source to G.U.N. robots and are dropped when they're destroyed. Once collected, they can be used for raising Chao, adding to one of their stats. Additionally, for Tails and Eggman, a Chaos Drive will recover the same health as one Ring does.

The Chaos Drives come in four colours, each tied to a particular Chao stat as listed below:

Colour Category Stat

Sonic the Hedgehog (2006)

In the 2006 Sonic the Hedgehog game, Chaos Drives are used to power Dr. Eggman's robots and are dropped alongside Light Cores when they're destroyed. As soon as they are released, they home in on the player's character, replenishing larger portions of their Action Gauge than Light Cores. A Chaos Drive also appears as the icon for the Gauge Up Item Box, which fully replenishes the character's Action Gauge when broken. As there are no Chao Gardens in this game, Chaos Drives cannot be used for raising Chao.

Compared to their appearance in Sonic Adventure 2, Chaos Drives in this game are not contained in capsules, and are coloured blue.

In other media

Sonic the Hedgehog (Archie comics)

In the Sonic the Hedgehog comic series and its spinoffs by Archie Comics, Chaos Drives were invented by Professor Gerald Robotnik and used as power sources for G.U.N. robots just like in Sonic Adventure 2. As shown in Sonic Universe #69, a Chaos Drive was also used as E-123 Omega's power core; its removal by Eclipse the Darkling had left Omega in a heavily weakened state.

Sonic the Hedgehog (IDW comics)

In the Sonic the Hedgehog comic series by IDW Publishing, a Chaos Drive was used as a power source for the Egg Walker. During Eggman's raid on Starline Base Sigma in issue #55, Surge overpowered the mech and ripped out the Chaos Drive, absorbing it into the Dynamo Cage to further add to her power.
