Cosmic Wall


 * Not to be cofused with Cosmic Fall

Cosmic Wall is the thirteenth stage in Sonic Adventure 2. When Eggman's detector senses two Chaos Emeralds belonging to Sonic and his friends (a real one and a fake one), Eggman climbs in his Egg Walker and sets out to the ARK to confront Sonic. He captures Amy and blackmails Sonic into giving him the Emerald in exchange for Amy's life. He encapsulates Sonic who attempts to give him the fake Emerald and sets the capsule to explode in space.
