So, Kid Boo and Goku SSJ3 (Vs Kid Boo), are the most powerful characters of the moment? More powerful than Super Vegito?
Hmm... It does seem most likely.
Remember this.
Enraged Buuhan ~ Super Saiyan Vegetto.
And Kid Buu is on a whole different level than Enraged Buuhan. So you have to think about if Goku included Enraged Buuhan into the conversation, I see no reason why not.
Also, the Super anime makes it clear that Goku defeating Kid Buu made him the #1 in the universe. Also the way Goku speaks to Goten about Kid Buu makes it appear that him coming back would be a tremendous battle for him again.
A while ago I started thinking that the greatest ki felt by Goku, before Super Baby Vegeta, must have been the Super Genkidama that killed Kid Boo. That Genkidama could be thousands of times more powerful than Kid Boo. Even Vegetto SSJ3 (Boo) would be complete fodder compared to Super Genkidama.
What do you think?
I initially thought it had to be Super Vegetto, but now if GT uses the TOEI Hax, which it probably does, then I'm not sure how to go about things.
