When the original My Little Pony toy line — preceded by her larger sister, My Pretty Pony — galloped onto the scene, it was something like we’d never seen before.

The first My Little Pony TV special was titled “Return to Midnight Castle,” and featured the ponies trying to rescue their friends from Tirek, who is basically Satan as a centaur.

Still, in “My Little Pony: The Movie,” the evil satyr Storm King (Liev Schreiber) has enslaved the ponies of Equestria with leather bridles, a look that unmistakably suggests S&M.
