A new sexist Prince (voiced by Enrique Iglesias) has arrived after becoming the first alicorn male. He hates all mares and believes they have too much power, and has a plan to over throw all the female princesses... Our mane heroines (and one self insert character Pinkie Pie loves to mention was crudely added by a mediocre writer...) must learn to defeat him after he uses a powerful hypnotic spell on all the stallions and forces them to rebel and join his new kingdom.
