Collision Chaos Zone

The Collision Chaos Zone is a pocket zone adjacent to Mobius Prime. It was created by Dr. Robotnik and used as the setting of a trap for Sonic the Hedgehog, using Amy Rose as bait. Part of the trap involved destroying the Zone behind Sonic as he ran through it, preventing him from retreating. Sonic confronted and defeated Metal Sonic in this Zone before rescuing Amy and returning home to Knothole. (StH: #25)
