So... is possible applying a background character from a series that has, like, 'no canon' but a very strong fancanon? I mean, I'm talking about Derpy Hooves from My Little Pony: friendship is magic... she's just a little mailmare who just keeps appearing in the background but she got one of the biggest fanbases of the series and there are few theories that are generally accepted from the whole fandom... and I wonder if I could try.
