We all know that these 3 Saiyans have no chance against Fat Boo but how about against Grey Boo who has the majority of Fat Boo number say like 60-70%? Can these Saiyans are strong enough to win?
I'd personally argue that Pure Evil Boo may very well be within Fat Boo's range, given scaling from the implication that Initial Evil Boo = Fat Boo (Moment of the split) and Initial Evil Boo (Piccolo's first impression) ~ SSJ Gotenks. That said, Boo wins just as easily, be he fat or skinny.
