You people are all wrong. I'd be the Nerevarine from TESIII: Morrowind. Think about it. He can use whatever magic he wants, he's rich as ****, he can fight and kill like anything that comes his way, he can do whatever he wants, he killed 4 flippin gods, (since I consider Dagoth Ur as much of a god as the Tribunal), and I just obsess over The Elder Scrolls anyway haha.
I would be NightWing from Batman: Arkham City because he has a vast under standing of acrobatics and martiel arts plus he looks cool and Is my favorite super hero.
The Dragonborn...I cannot be killed by logical means, I can climb the tallest mountain in the world in 20 minutes with no previous training whatsoever, and I can go around killing people as I wish with no serious consequences.
Maybe Alex Mercer...though I feel like I might end up putting the world into total disarray...I'll think of another next time though for now it's Alex. XD
John marston maybe, although he really does get old after a while haha. same with niko bellic. actually that goes for a lot of playable characters for the 360..
