I uh.. think this is my first submitted image of my ponysona, Ashen Hoof.

Ashen Hoof is a unicorn, whose magic specializes in pyro type things. She is capable of summoning fireballs at will, though the larger it is, the more effort it requires on her part and therefore the more strength it takes from her body.
She's a cynical smartass who loves to debate, although she's actually very withdrawn and not easily drawn into arguments.
