The Vengence of a Centaur Princess' Sister

Princess Alice's evil eldest sister Zeilda, a centaur sorceress who was banished by Queen Abigale for trying to take her youngest sister's birthright to rule Equestria's centuars using dark magic has returned and is recruited by Mirage and Master Xehanort to capture Kairi, Spongebob and Spyro for their plains. She kidnaps the Mane 5 with the help of Maleficent, Pete, Fagin, Professor Ratigan, Discord and Queen Chrysalis hopping to lure Alice, Twilight, Spike and Taiku to them and demands to bring Spongebob, Spyro and Kairi with them without the louge in exchange in letting Twilight's friends go and make her the Empress of all of Equestria's Centaurs. Will Zeilda be as vengeful as Sing Jin Sue? Not if the four best friends of Magic University and the Celestial Sisters have anything to sat about it!
