Found this IMDB listing American VAs with pony roles

[Steve Piranha 28,782]

I have found this list. I’m not sure if this is a fan-wish list or those castings are official. I tried looking for Cherami Leigh who apparently voiced Lyra, so that points on being fake. But also list Tara Strong and Trevor Devall (who’s now based in LA) with their respective roles. Anyone can confirm?

 

PS: I know Kira Buckland voiced at least Twi and Applejack in app releases of pony episodes

It mentions Funanimation who have nothing to do with MLP, so it appears to be just a "what if". The same person who made the list appears to have made similar ones for other shows.

As for IMDb, unfortunately even the actual credit listings there are less reliable than before, a lot of obviously fake credits on some shows.
