This is Blight. She's not naturally a giant, but she just sometimes like to assert who she is to those lower than her. Unfortunately, that normally ends in painful death :S
That's her feral form, by the way. She's usually on all fours, but will get up on two legs once in a while. She can also retract her wings so that they aren't visible, except for the fact that some of the spurs are sticking out of the backs of her arms. She's a bat-fossa mix.
Will get a proper reference image out whenever I feel like it xD
