Well I would have to say that if your not counting GT(shouldn't of been made) then I could see it being either Gohan or Goku. When Goku was SS3 he even stated he could've beat Buu but that a new age of heroes was at hand. Also when Gohan was Ultimate/Mystic Gohan he was easily owning Super Buu, but he became more like Vegeta and got to cocky. So with that being said I would say Gohan because he could've taken Super Buu where as Goku could take Majin Buu.
I'm gonna have to go by the anime. (DBGT)
That's Goku for Two reasons:
1)Super Sayian 4. Pretty much enough said. He was the first to attain it.
2) He's the main character, right? They're usually the strongest no matter what. Wouldn't be much of an anime if at some point the main character somehow becomes stronger than all the rest.
I thought Gohan was the strongest of all. But I'm not sure though. It's true that Goku has reached Super Sayian 4 before anyone else. But I think his son is the most talented. At a young age he got to be a Sayian and he got trained by the strongest people including Goku. And he is the one with the potential to surpass his father.
Goku has gone to super 4. I don't know how you can beat that. You'd have to use fusion or something. I dont know.
Bow to super saiyan 4!!:worship:
Well any one of the sayians can supress he other because they have the power to grow from strong fights but Goku fought all the strong enemys and DragonBall Z ended saying that there were no more enemys to fight for Goku and his crew so there was really nobody else to fight and get highly trained up for the only person who well continue to train well be vegeta in hoping to suprass Goku but Gohan well go to school and so well porbaly Goten Trunks well probaly train but not well not suprass Goku in just traing Future Trunks might get stronger than Goku probaly has the best chance and but Goku well probaly train still and be the Strongest of them all because as i said you cant beat Goku by just training and the only time Goku well lose is when he gets old like his sensei.
I stopped watching the series after they turned to do the new one where he was sent in time or something, i think it completely ruined the storyline but i would say that Goku for two reasons, He is really cool and two he is the main character and always wins. My liking for DragonBall faded when Boo was defeated it just stopped being good. Supersaiyen 3 was enough not 4. It's strange because Trunks sent from the future was so powerful but as the episodes went on he was just annother Goku wannabie like they all end up to be. I loved the storyline and never missed an episode, my favourite season would ahve to be the cell season or freezer with the little short storylines mixed with the long ones made this a really good programme, but Gohan changed a little from freezers episode to cell's, he kicked ass :p
Goku is, He almost never gives up, even if he is killed...he just comes back for more, or goes ssj4 and pwns.
