True, he did say that. However, that was AFTER he absorbed South Kai, which made him stronger. He's weaker than Buff Buu, but still quite a bit stronger than Kid Buu. However, his disposition is such that he'll never go nearly as far out as Kid Buu does. Kid Buu is incredibly dangerous, as he doesn't hesitate in doing anything. Not the strongest, but definitely the most dangerous.
🙄 Ahh yes the ever...something...absorption logic. Its true guys, Majin Buu gets weaker each time he absorbs someone, firstly he finally found someone comparable with him in strength (South Kaioshin) so abosrbed him because he wanted to get weaker, then he found someone else, once again on a level of strength equal to his (Dai Kaioshin) and absorbed him also.
Many, many years later after obtaining the form known as super buu he came across someone known as gohan who was wiping the floor with him. Buu thought to himself "Hmmm, im never gonna beat this guy am i? unless... i know!! i'll absorb Piccolo and Gotenks to become even weaker!! Gohan won't know what hit him, heh heh heh"
Ahh yes, Dragonball Z: The Battle to Become the Weakest
....Right
If Kid Buu is the weakest, that would mean he is stronger then Super Buu 3. Now, why in the blue hell did Goku fuse with Vegeta to fight Super Buu 3 if he's weak compaired to Kid Buu and why did they both crush their earrings before the fight with Kid Buu?
You guys are also saying that SSj3 Goku is stronger then the fusion is part of.
If by that you mean by using facts from the manga, rather than the dub anime, which not only is full of plotholes (For example: Pikkon>Perfect Cell>SSJ Goku>Pikkon? WTF kind of sense does that make?)
Seriously, the only facts for DBZ comes from the manga. The anime, especially the dub anime, isn't completely correct.
