Mr. Satan serves as the comic relief of the DragonballZ series. He takes full credit for the destruction of Cell and considers all of the powers of the Z fighters mere illusions. During the DragonballGT series Mr. Satan is the leader of a Dojo and Pan (his grand-daughter) whipes out all of his students just for fun. He does do some good things, such as bringing the remains of Android #16 to Gohan to trigger him to go SSJ2 and he also conviced earth to hold up there arms and contribute there energy to Goku's Genki Dama.
