Buu is still known as one of the strongest beings in the DBZ universe and it’s hard to deny that his fighting abilities are incredible. Mystic Gohan was able to give him a pretty good fight and he had the upper hand for quite a while. Of course, Buu got his Gohan form later on so Gohan shouldn’t be too much of a threat to him at this point. Gohan’s going to need a Super Saiyan God power up if he wants to take down Buu in a potential rematch. The majin is just too powerful at this point. Buu wins.
