I love the title "Soldier of Fortune" (because it reminds me of the Wild Geese from Hellsing), but I usually also alternate between "of the Silver Lining" (makes you sound like a nice sort of person somehow), "Green Eyes" (um... because my eyes are green) and "the Exterminator" (because awesome, that's all). XD

Right now I'm digging the Triple Triad titles though!
