Isaac

My boy Broly just laying low in the background for now

Also he was almost equal to SSJ Blue Evolved Gogeta

But he lost cause

1. Gogeta had way more experience

2. He only focused on offense and attacks while Gogeta was smarter in dodging and redirecting his punches while using counter attacks

3. Even tho he still had the stamina to continue his body was getting worn down from the new power he gained seeing it's his first transformation and caused his great pain and rage throughout the movie

4. Gogeta has a whole already has haxes and special abilities due to being a fusion has we saw against Janemba

This is just for the movie not the current mangaka

Jiraiya, Kakashi barely though him anything only Asumas guide on wind chakra, Yamato with the Shadow Clone idea and Sage training were the only good feats of training he received he came up with every jutsu apart from the shadow clone and rasengsn

Two jutsus my boy
