And as always, DBZ is underestimated. This is why DBZ shouldn't be in battle threads because they are underestimated by everyone.
Vegito: Planet Buster, he has never shown any ability or power that prove otherwise.
Super Buu, Kid Buu, any Buu: Planet Buster.
Galactus: Universe buster, he is the big bang, he is a force of nature. Universe Buster.
Silver Surfer: Has shown on panel countless times that he can easily drain and destroy most superheroes and planets.
Thanos: Stood up to Galactus. Took Silver Surfer's strongest shot and then knocked him out.
Vegito loses badly.
