He was never quite the same after watching it, he had strange hallucinations about a girl with ponytails and black hair

If you get somebody into anime they should start with something less popular.
Something that does not have any weird boob things or awkward scenes.
That stuff is for later when they actually get into anime.

It's to late... he won't stop saying nah I'd win

start him off with something fun like dragonball

I did after he finished jujutsu kaisen but that was a mistake he loved geto and... he is in love with Freiza

show him the super broly movie

He watched everything except for the z broly movie

ive watched it before its pretty good but i am unsure if it is canon for the dragon ball universe, but its a good movie nonetheless
