Hanzo should win this. He was really out of his prime when he died to Pein and the version of him that was revived to fight against Mifune was obviously the same one that died.
Broly has one feat worth mentioning. A feat that was only shown at the beginning of the first film. Are there any other feats for him that shows him being superior to SSJ2 Teen Gohan? SSJ2 Gohan who manhandled all the Cell Jr's with complete ease, who were themselves slightly stronger than Ascended SSJs Trunks and Vegeta.
Hatchiyack was also mentioned as being possibly stronger than Broly in the movie "Plan to eradicate the Super Sayains".
Now I will concede that after his zenkai, in the second movie, he was a lot stronger and much more powerful than a SSJ2 but to say that he's equal to a SSJ3 is ridiculous. Remember the difference in power between even a Full Powered SSJ and a SSJ2? The gap between SSJ3 and SSJ2 is even larger, much larger.
@taichokage: The copy character was for a little. He never showed using it longer. Broly insults him then blasts him. Janemba has nothing on Broly. Also Broly has his shield so attacks of a warping Janemba is useless.
Yeah, keep shouting those KAKAROOOOOOT's. That's gonna insult him real good. Probably leave an emotional scar behind, too.
