If I Was a Super Hero

If I had any super powers I'd want to be a vampire. I'd want to be able to stick my nails into concrete walls and climb up them at a very fast pace. I wouldn't mind having almost eternal life. I also wouldn't be a blood sucker to the death of humans, like how people make them seem like they're evil. I'd do it for the good. I would take a little blood from many humans to satisfy my vampire needs. I would also be invisible in war. I'd help protect our country if somebody like Iraq decided to airplane bomb us again or something similar. I'd help take murderers off the street by sucking their veins dry. The only person that I would make sure knew who or what I was would have to be the president of the United States.
