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.

The Chaos Devil later encountered Sonic and Mega Man in Issue 27. After their attacks failed to work on defeating its eye, they tried to do a similar combo to the one they used to restore Tails Man to Miles Tails Prower, but it only resulted in Sonic getting stuck inside the Chaos Devil. It eventually was dissipated by Duo's arrival. Duo then proceeded to hold it off while Sonic and Mega Man tried to stop Eggman and Wily, and sensed that it had mental and emotional conflict in itself, due to it incorporating both a noble creature and an evil demon inside it.
