My character name is usually "Rik Wilson" - when I'm playing a guy. I know, it's not particularly heroic.
It's a tradition from the first computer RPG I ever played - Temple of Apshai on an Apple ][c in 1985 or so. I made a character (read: blundered through the character creation process guessing what the stats and numbers meant), and when it asked "What is thy character's name?" I was stumped. The nearest book was the manual for the game. I opened it to the first page, and looked at the names of everyone who contributed to making the game. One of the play testers was a guy named "Rik Wilson". And the name has forever stuck.
I tell ya what, Rik has been through some serious shit.
He's been the Bhaalspawn, he's fought Super Mutants in the wasteland, he slew a beholder beneath Neverwinter, he became a Baron with an 'Elite' kill rating for the Empire, he battled the Dark Savant across time and space, he was a vampire in LA, and once he was a roaming swordsman in Edo-jidai Japan (not many people with the name 'Wilson' in that place let me tell you).
Alternatively, in online games, I'm usually 'UZO' or some derivative of "Uzofiel" - an Age of Conan demonologist Stygian named 'Uzophrates', and in Secret World I was "Agent U20").
