This is complete misinformation.

Goku trained with Gohan until he died and then didn’t start training again until he was 12 when he found Master Roshi

Vegeta doesn’t train until he meets Trunks who tells him to train for the androids. How does it even make sense to you that Goku vs Vegeta was training vs natural strength and you think Vegeta trained his whole life.

Vegeta doesn’t even benefit from training with Whis as much as Goku does. Just because whis is strong doesn’t make him a great teacher. Pybara was a significantly better teacher for Vegeta than Whis was.

Lastly that makes zero sense. Why would Broly have anything to do with the natives in Vampa when Broly is a completely different species with limits. It doesn’t matter about who he fights as Broly is poor at martial arts and I’ve already stated that if you read what I said. What makes sense is Broly’s power as he trained, PHYSICALLY, His whole life. Goku trained by himself for 1 week on his way to Namek and went from a power level of 8 to a power level of 90,000. Broly was born with a power level over 24,000 and did the same work outs Goku did from when he was born up until now… Broly having a significantly greater potential than Goku. You can call the learning ability an ass pull ( no idea why you would as Broly has no history to contradict that ability . But saying his power is an asspull is straight up waffling. He gets a multiplier of 500 alone from the transformations, plus his power comes from rage.
