Nonaggression

Nonaggression is the final stage of Sonic Advance 3. After Gemerl betrayed Eggman by throwing him into Sonic, Sonic dropped the Emeralds and Gemerl used their power to transform into a super powered orb-like enemy. Sonic then used the Chaos Emeralds to become Super Sonic and teamed up with Eggman to bring the out of control Gizoid down. What Sonic has to do, is transfer his power into Eggman's Egg Mobile and throw him at Gemerl's shieled "eye" and Sonic has to dash and hit the "eye". At points, Gemerl will attack using rockets or extend his "arms" to fire laser beams to stop Eggman and Sonic.

At the end of the fight, Gemerl changes back to his normal form and Cream finds Gemerl once again. Heavily damaged, Tails repairs him and Gemerl clearly remembers Cream and the two become friens once again.
