The Moon Zone

The Moon Zone is the final stage of Sonic Advance. After completing the X Zone, if the player has all the Chaos Emeralds, finished the game with all the characters, and finished the X Zone with Sonic, he'll transform into Super Sonic and fight Eggman on the surface of the moon. This boss is pretty simple, jump and dash when his head is exposed. Sometimes, Eggman will fire a pod, if it catches Sonic, he'll stay inside the pod until he manages to break free. If charged at, the pod will release rings. Eggman will also fire a laser which doesn't really do anything, but it will knock Super Sonic back a little. After defeating the mech, Sonic will disappear for a few days. Then while Tails is flying the Tornado, he spots a streaking yellow light, which turns out to be Sonic (still in his Super form). He'll give a smile and the credits will play.
