For personal reasons, the Flash, since the first superhero comic I ever read was the Flash. I mean, he also has a great power; you take can your flight/invisibility scissor statement, but I'd drop either of them in favor of being able to move faster.
But I also have a favorite obscure superhero. The character is called "The Black Hood" and he was published by Impact! comics (Archive comics superheroes). Wore a cursed executioner's hood. The Black Hood had a really neat visual and street level spooky powers.
