Same. Grade 2 Vegeta and Trunks would have taken care of Cell Jr
heck, if Goku used it he would be able to fight 100% Cell
Grade 2 boost is very high judging from Vegeta’s transformation sequence
It requires damage. Moro states it
it was stupid. Moro dodged Vegeta effortlessly, showing that spirit fission is useless when the enemy is much stronger
so Gogeta/Vegito wouldnt have had problems with Moro
