Wikipedia says
A superhero or superheroine is a stock character that typically possesses superpowers, abilities beyond those of ordinary people, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime.
So yes, he is definitely dedicated to protecting the public, but it feels wrong to call him a super hero. What do you think?
I do think there’s a good amount of characters who you don’t think of as “superheroes” but really are…but I don’t think Skywalker is one of them. His skills aren’t rare, he’s just one of the best, and his motivations are more that of a freedom fighter/terrorist (the difference is perspective) than a peacekeeper (I actually would argue that a superhero could be a freedom fighter, but most are peacekeepers.)
