Yeah, absolutely. Make up your own weird failed hero, have them work a blue collar job to pay the bills. Hilarity ensues.
Heck, if you play the animal hero, you get to choose whatever weird animal you want and tell everyone else how being bitten by a radioactive platypus gives you the ability to lay eggs and produce milk at the same time, or whatever. Proportionate strength of a walrus or what have you. Get creative, make up something funny and dumb, give them an outrageous accent and have a fun time.
