Goku

Goku has become one of the most broken (in terms of power) characters of the Anime Universe. We're waiting for next Thursday's patch to see if he gets nerfed.

Origin
It all began when Shaggy failed to takedown The Abyss. Matt Final Orion God Form decided that the only way to rectify his mistake would be to make an even bigger mistake.

Long story short, Matt instituted the Super Saiyan form so Goku would teach it to other people. This form was inspired by the original Cosmic Shaggy form. Unfortunately, Goku's bullshit form isn't bullshit enough to destroy the Abyss so that sucks.
