Who is the most complex character every created? The one whose decisions most resemble a real-life human being?

The answer for me is any character I create in an RPG. My toons are not down the line good or evil or good guy or prick (to criticize Bioware's shallow view of morality).

My Dwarf Hunter in the World of Warcraft is very human. He has his prejudices (killing elves on sight regardless of max level or level 1), has his preferences (treating Orcs and all the other ugly races of the Horde as wary neutrals unless they fire the first shot), and he is never afraid to vote kick a player for low DPS, ninja looting, can't heal worth a damn, or if my guildies in the run initiate the vote kick.

As for characters I have not created...No premade protagonist or party member has resembled anything close to human. All have been caricatures of one sort or the other be it the bimbo, whiny faggoty male, deadpan humor clown, drunken fool, and on.
