Daimao+Vegito=Dagito
But I just created that. And you can forget about it. And yes I am Stein. Daimao just changed my name to more royalty than Stein. I am the Prince of Saiyans.

i think one of the nazgûl maybe (yes, they have made anime about lotr too)...
strongest of em might be KHAMÛL (or Witch-king of Angmar)......

you know you go wayy off topic too much sometimes..

anyways i'm gonan stick to OFFICIAL manga's /animes

i think goku was supposed to be stupidly powerfull compared to a lot of characters in animes..

like if you look at naruto, bleach, once piece, etc.. there doesnt seem to be a constant threat of the whole world/solar system being atomised..

so i'm gonna have to go with goku.. but i think if super buu had absorbed enough of the Z fighters he would've been too powerfull and then become the most powerfull thing that ever lived

LOTR anime?

I heard about a old cartoon, but an anime??

Well Goku...
Gohan and Goten should have been stronger. They became Super Saiyans at a very young age, so they would have the time to become much stronger saiyans then Goku, even if they are half-saiyans.
