antihero = common or everyday man who 'bucks' the 'system' ie. goes against the mainstream rules of accepted modern society's values.

i would agree strongly with jNj and add the following :

1. the stranger from any of the early sergio westerns
2. james dean from Rebel Without A Cause
3. kelly from Kelly's Heros
4. cpt. virgil (steve mcqueen) "the cooler king" from The Great Escape
5. paccino in Dog Day Afternoon

and though i wouldn't put him on my top 20 list of great antiheros, yeah even napoleon.
