Jade from Beyond Good and Evil, Garret from the Thief series, Gordon Freeman from Half Life, Agent 47 from Hitman proven he won't kill me (although it would be scary), Raziel from Legacy of Kain series, SHODAN from System Shock 2, Isaac Clarke from Dead Space, GLaDOS from Portal, P.B. Winterbotom from The Misadventure of P.B. Winterbottom, Jaaaaaaaaaames Sunderland! from Silent Hill 2, Heather from Silent Hill 3 and/or Philip from Penumbra.
So as you can see, I love many characters. Also I would like to meet The Darkness from The Darkness, but I think it doesn't count as a character.
