I'm back,so thanks for the comments. Yeah goku and gohan are strong,but then again gohan can also turn into super saiyan 4 also,just that goku was the first one to be one.they're both cute,and they are really entertaining.
I say both. here's why:
i say Gohan because when Gohan was a teenager,he was stronger than Goku ever was. The only reason Goku became stronger, is because Chi-Chi made Gohan stop focusing on fighting and training and stuff,and focus on school stuff.
I say Goku because Goku saved the planet more times then Gohan did.
