Any decent superhero games that are completely original? (i.e., not DC or Marvel, etc.)

I'm familiar with the superhero genre, obviously, but after playing all the Arkham games and seeing all the Marvel stuff, it had me wondering if anybody had gotten around to creating a decent game in the superhero genre using a completely original universe? Brand-new superheroes have the handicap of having no name recognition and no existing lore to tap into, but it could also provide opportunities for having a blank slate, etc.

Honestly, I'm just curious if it's been done much at all, but if anyone has suggestions that are worth playing, that would be even better.

Thank you.

EDIT: WHOA, thanks for the suggestions, everyone! Didn't realize there were so many. I'll have to look into these.
