Gaomon has a whole lot of super forms so he won’t go down here very easily. That being said, I think Vegeta is definitely the character with the edge here. His super strength and speed are off the charts and he seems to get stronger and stronger with every arc. Gaomon is out of luck here because his physical stats just aren’t quite good enough to match up to Vegeta’s. It’s like a cub taking on a lion. Vegeta wins.
