The Controller serves to unify the Chaos. One hero in all the world, chosen to Control the Chaos. Sonic the Hedgehog is that Controller. And in the past, just as in the future, there live other heroes, other Controllers who use the Chaos Emeralds to maintain balance in the world, fighting back against whatever darkness comes. This is the story of the Controller.

Two hedgehogs. One from a utopic future, the other an apocalyptic past. One longs for grand adventure, the other for a quiet life. When the Time Eater returns, threatening to destroy all timelines, these most unlikely of friends must team up to save all of time from a terrible evil once thought erased. A Chaos Project spin-off. Written by Yuni Oha of the Cosmic Quest project.
