BATMAN:
became superhero because his parents died
has lots of money and is highly intelligent and knows kong-fu
never kills people and has morals because his parents are ghosts
has died lots of time, had his back broken and served in nam because he is true american hero™
SUPERMAN:
his parents are dead and he escaped his planet just before it exploded
has infinite power and every single power but doesn't remember them because he had a bad migraine this one time and then he convientently remembers them
has died but came back to life to sell more comic books
although stronger than anything, he sometimes gets hurt cuz comic book writers are hacks
gets upset when peopel dont like facebook statuses
SPIDERMAN:
became a superhero cuz a spider bit his dick which turned into a gigantic fucking dick he retorts some tedious bullshit
his uncle died by the way, he taught him that you should cum on peoples faces and never look back
can shoot jizz out of his wrists
in conclusion, all comic book characters are completely shit, poorly written and are just used as forms of validation by nerds
