Um . . . in my fanfic twilight & flash have a colt. This is a cross with DP. So, anyway, their colt's an alicorn. He's black with a white mane and tail as well as silver hooves, wing tips (the actual feathers are white) and silver horn. He's got Danny's ghost powers (born in ghost zone. Don't ask me why) and telekinesis. I'm A) curious as to what DP villains should appear, B) what MLP villains should come into play and C)will this even work.
Also, how would a horse's ghostly wail sound?
Finally, there's a ghost zone (and a human but none of their portals are up and going so forget them) and the ghosts are huminoid.
