Quincredible Vol. 1:

Invulnerability is a pretty useless superpower if you've only got a one hundred pound frame to back it up. That's what Quinton West's life became when he went from small guy who got beat up to small guy who can't get hurt after the meteor shower dubbed 'The Event' gifted him the power of invulnerability but no other powers to compliment it. But there's more to Quin than meets the eye, and Quin realizes that he can use his quirky hobby of creating Rube Goldberg-like devices to outsmart the opposition.
