Kid buu is not te only one who can destroy the planet with his move, and my advice is dont just go for power, i can beat most people using tapion and he is considered one of the weaker characters damagewise but has amazingly long and inescapable combos + hero flute is a god send against any powerful character

Yeah strongest best character is had because those hat have powerful moves tend to be weaker in the combo department each character has flaws which can be addressed with Z items so technically you can make any character acceptable to play with. Yes U Gohan is n awesome character he is normally 2nd on my list after tapion.

there are a few moves like that though. tapion has one kid bu has one aswell i think
