Rainbow_D

Apparently she's got a bit of magic to her as well. Of course, this shouldn't be too surprising considering she's the fastest pegasus around. Coming from Equestria to these lands has given her the ability to shift between her "feral" pony form to a human form. As well as also granting her some other limited shape-shifting abilities. Regardless of form, she's still fast as heck, playful, competitive, and of course, loyal to her friends to the end.
