THE ULTIMATE CROSSOVER (feel free to add to this)
dio and dream. they are perfect friends, dream is a child manipulator and dio is well... dio also they are both pretty big antagonists in their respective fandoms
Joseph joestar and philza. they would likely have wars on who is older, philza would win every time. they are both generally those father figure-ish characters? even though joseph is a grandpa but eh. SO IS PHIL well except phil's kids are all problem children.
I cant think of any more so feel free to add
