Vegeta just thrust his hair and the battle would be over
@OfficialRikudouSennin: Minority World says hi.
lol inside buu a permanent fusion doesnt last 1 sec and vegetto with his ki shield stayed fused till he deactived his ki shield and on the next panel he defused.
since ki dont have atoms to manipulate. and well vegetto used a ki shield to let himself being absorbed but not absorbed to give buu power.
I Hope you do realize that even if the ki shield didn't have any atoms to manipulate Vegeta him self would still be affected due to the fact He still has atoms.
