Anita Blake, Lestat, RaizoOk, well my hero is Anita Blake, a completely fictional character from a series written by Laurel k Hamilton. If currently I could run away with one character it would be Raizo from ninja assassin, sorry but he's freakin hot. A long time love interest of mine is Lestat from Anne Rices Vampire chronicles.
I think the obsession I have with these characters is that they are everything that you can not get in real life. Men are not like that in real life (even if you take away the whole vampy/ninja thing) I'm not much like Anita but I wish I was etc etc.
