Tetsudah... Vegeta dosent only use that on Buu...
He also uses in it the Sayan saga... Or im pretty sure he does.
But i cant remember the name of it...

But i have used it in a DBZ RPG for Nintendo..
Think it was called Syogekina... or something...
But in the game it was a invisible beam/force/attack.
and Bakahatsuha is Nappas attack
He uses it to destroy the city.
though i read that Vegeta used it to..

------>>>
But editing his Renzuko would be a good idea...
Cause its not just fast fired ki blasts... its a move...
But how to make it different... yea... the way he used it
against Cell... Maybe... could be...
But His "Noname" attack is pretty good and no one
els uses it... So would make him more special
