Tirek.

A white winged unicorn logo appears against a dark, cloudy sky, then the scene cuts to a purple pony with a pink and purple mane peeking from behind a wall. The view shifts to a large, red-skinned, horned creature with a white beard and black vest, standing in a dark, mountainous landscape with swirling clouds. The creature's face fills the screen, showing a glowing yellow eye with a red slit pupil. The scene cuts back to the purple pony, now lying on the ground in a desolate, fiery landscape, looking up with a determined expression as a dark, shadowy figure looms in the background.
