I enjoy AU stories, specifically seeing how the canon timeline can be changed with the addition of new characters or scenarios.
I like writing about the worst day of a character's life; it lets us see the mettle inside. (Pronouns: RB/20 )
A pony with too much time on his hooves and too much plot to work with, in more ways than one. Porn Pope (TM). Also on FA!
Canon x OC, that's my specialty, both in art and in MLP stories
