This is Petra, and she's a pirate. As if you couldn't figure that out from the picture, and especially from THAT *points at pic title*
While Petra is still fairly young, she has been a pirate for much of her life. I would advise not to get on her bad side, unless you have a wish to walk the plank!
I am fully aware of this picture's most dreadful lack of background, and who knows, perhaps someday I will get around to adding one!
