The Collision Chaos Zone is a location on the Little Planet. During his adventure to liberate the planet from Dr. Eggman's clutches, Sonic the Hedgehog initially wondered into the zone with Amy Rose in tow, after defeating Eggman in the Palmtree Panic Zone. It was here that Sonic encountered Metal Sonic for the first time, who kidnapped Amy and flew off, leaving Sonic to give chase. (StH: #290)
