One I can personally recommend is
How To Be A Superhero by Mark Leigh and Mike Lepine. But it's very very silly.
There's also
How to Be a Superhero: Your Complet...ing the Forces of Evil, and Much More! by Doctor Metropolis, which I haven't read.
These are links to Amazon UK, they may be on Amazon.com too but I haven't checked.
Another one that may be of interest is the comic
Dr. Blink: Superhero Shrink by John Kovalic and Christopher Jones, which is good fun and goes back to the original theme of psychology. See in particular the Captain Omnipotent story, about a character whose history is somehow familiar
A last rec:
Evil Inc. by Brad J. Guigar is a web-comic about an organisation that supplies services to the supervillain industry. It's extremely funny.
