I guess Black Canary does that. She has a superpower, but she also learned how to fight. But her superpower is just yelling really loud, so it makes sense that she'd want another way to solve her problems.

But they took away her superpower in that Arrow show for some reason. So she was just a fighting person with a sonic device that nobody else ever used. Maybe they wanted to keep it "realistic", but then they introduced The Flash and an Iron-Man wanna-be, so idk.
