Choosing Origins

After reading everything here it looks like Star Spangled Bat will be a Natural. That's my Martial Arts/Shield Scrapper. It's based off of Batman and Captain America. I went Science for my Claws/Invulnerability/Flight Brute named Super-Claw, I have based off of Wolverine and Superman. Not sure if it's a good fit or not.

If a guy whose born with special powers donates blood to a normal person. Would that be considered a Science Origin then? If it granted the normal guy with powers from his donor albeit very weak powers, cuz of just a blood donation.

The blood transfusion sound slike science to me, Captain.

(unless its vampire or demon blood, or something magical)

wow, I don't think I've seen so much about origin in this game. I have always gone mutant. I have found that if I ever want to create a story for a toon later on mutant can sum almost anything up and the main person I have gamed with since start is a mutant which allows exchanging of enhancements. Things just work out best for me as a mutant, in both story and gaming.
