Derpy Hooves from My Little Pony: Friendship is Magic, cosplaying as Ezio Auditore from the Assassin's Creed series.
Drawn for my younger brother for his birthday >3
Last I year I drew him Derpy cosplaying Cole McGrath [link]
and though his favourite pony is still Derpy, he took a much bigger liking to the AC series. Well, it doesn't work as perfect as the Derpy/Cole crossover, but I guess it works somehow... why do you think Derpy is always sneaking in the background? Assassination missions obviously >D
