Pinkamena Diane Pie is the nightmarish version of the ever-smiling Pinkie Pie from My Little Pony: Friendship is Magic. Unlike her bubbly counterpart, Pinkamena is a deceitful, sadistic Killer, and violent pony who lures ponies to her basement, tortures them, and bakes them into cupcakes, who hides her bloodlust beneath a cheerful voice and unsettling grin. When her mane deflates and straightens, you know the fun is over—and the horror begins.
