dude from jojo part 2 defeated some ancient aztec war gods who were kinda somewhat also vampires I think…but anyway the nazis woke them up and these aztec bros needed this magic crystal to rule the world so dude from jojo part 2 had it and defeated them one by one and the last dude was exploded into orbit

fast forward to part 3, jojo (joseph) is now old and his edgy grandson, also jojo (jotaro), all the sudden has this mystical being he can emanate through his body at will and punch stuff into oblivion, later understood to be a Stand (named Star Platinum)

anyways this younger jojo’s mother is hit by an enemy’s stand or something and becomes violently ill

so old jojo recruits young jojo and a few others, all of which have their own Stands, to slowly work their way up the bad-guy (and their stands) ladder to get to Dio, the leader of this enemy group, who was also the main villain from jojo part 1, and whom’s Stand is OP

got it
