Fans of all ages are gearing up for the season finale of the Hub Network's most talked-about show, My Little Pony: Friendship is Magic.

It's been a big year for the 'toon that has included, among other highlights, a guest appearance by "Weird Al" Yankovic. Today I have an exclusive clip from the May 10 two-parter that features everyone's favorite dragonequus, Discord (voiced by John de Lancie).

For the diehards, here's a description for part one of "Twilight's Kingdom":

When a villain escapes Tartarus, Princess Celestia chooses Discord to help track him down instead of Princess Twilight. Meanwhile, prompted to prove that she has an important role to play, Twilight turns her focus to opening the Tree of Harmony chest.

And part two:

In order to protect their magic, as well as the fate of Equestria, Princess Celestia, Princess Luna and Princess Cadance transfer all of their magical power to Twilight.

The season finale of My Little Pony: Friendship is Magic airs May 10 on the Hub Network from 10-11 a.m. ET.
