Phew... Good question. I would probably be Strawbluey (see my signature), since she's kind of like my Original Charrie (OC) thing.
However, one of my most beloved characters, Allegra (seen in my avvie) is a lot like me, personality-wise. Two years ago, when I first joined a wolf RP called Divided Skies with her, I didn't exactly have a background for her. xD I essentially gave her most of my own personality traits, and the storyline went from there. While she's probably been through a more cataclysmic life than I have (she's led a pack through countless crisis, lost two mates, five pups, two of her grandpups, and so on), she still seems to reflect a lot of my own attributes. So.
OOC, I would Strawbluey, but in a roleplay, I would be Allegra. c:
