So I woke up the other day and the first thing that popped into my head was the image of Twilight as Rip van Winkle from the Hellsing Ultimate OVA series. So I thought "Why not?"
Don't know who she is? [link]
Yeah I know, I don't think Twilight Sparkle would match this character at all should they ever ponify it either. Personally I think she'd make a good Alucard.
