Father of Harry Potter, husband of Lilly Potter.
Dude was kind of a dick. He was a school bully for one thing. His favorite victim? One Severus Snape.
Actually I think I’ll add that one to the “Hogwarts is a terrible school” list, because it hasn’t changed one bit by Harry’s time. “Rampant, unrestrained bullying.”
Also, he was a dick to Vernon. Not that Vernon wasn’t also a dick, but one must take the high road when dealing with such people.
It’s mostly his fault that Snape and Dursley treat Harry so poorly.
Rowling needs to write more about this guy and explain in depth how he supposedly (key word there) cleaned up his act, because as it stands, the only thing he has going for him is “Was against Voldemort”, and that’s not enough.
The Joker is against Nazis and refused to team up with Red Skull. That doesn’t make The Joker not a bad guy.
