Chaos Devil

The Chaos Devil was a variant of the Devil line that was created by Drs Eggman and Wily. Its basic design was indicative of the Devil line, but it incorporated elements of the God of Destruction Chaos from Eggman's dimension. Overall, it was incapable of differentiating friend from foe when unleashed, and could only be commanded by Eggman.

It was released by Rouge the Bat when she was discovered. It made short work of Bass and Metal Sonic before Eggman commanded it to stop.
