The anime and the "strongest" Boo thing...

[Desassina]

Do you think that Pure Boo has a calm state like all the others? Remember when Majin Boo came out the first time and Gohan thought that he could take him? That was before he powered up, so I was wondering if SSJ2 Goku fought against a calm Pure Boo, because the latter has most likely increased in power. With that being said, what Goku may have witnessed after South Kaioshin Boo reverted was actually a suppressed form. If we go like this:

Pure Boo - 200 (50%) -> 400 (100%)
Evil Boo - 160 (initial) -> 320 (max)
Good Boo - 80 (calm) -> 160 (angry)

Then Evil Boo's max is South Kaioshin Boo, who has Pure Boo's power locked to 80%, which is higher than his calm state. It's one way to look at the events from the anime, quite honestly.

I'm pretty sure Kid Boo has a calm state. Vegeta actually thought Kid Boo was in his league, but once he saw how powerful he was while fighting Goku, he realized that he underestimated him. All of the Boo's seem to have this.

Super Buu>Kd Buu>Evil Buu>Fat Buu

As for the alternate interpretations, I answered them. You basically claimed that Gohan didn't count as a Saiyan since Vegeta when Goku is the strongest Saiyan. If you responded to that point then I missed it. Also, Daizenshuu pointing out that Buu was the strongest in the universe when he was defeated has no plausible alternate interpretation either. It's as clear it can get actually.

I disagree. (Assuming I understand under all these quotes what we're still talking about.) Pure Buu and Super Buu don't exist at the same time. Pure Buu could've potentially been the strongest being at that point, but I don't take that statement alone to mean he was the strongest being anyone has seen ever. That would put him above Super Vegetto if true which I think would be a difficult argument to make.

Edit: I realize I simultaneously used and overlooked the "at the time he was defeated" line in which case Vegetto doesn't matter. I personally don't see Pure Buu above Gohan because I've always had Gohan above Goku at this point (which now I understand how that got started and people seem divided on that as it would be a detail that sort of lines up your side of this argument.) This is all a big mess of details, isn't it? Haha. Apologies for my swing-and-a-miss.
