is Luke Skywalker a superhero?

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?
