Grogar is a villain from My Little Pony and Friends that appeared as the main antagonist in the four-part story arc, The Return of Tambelon. He is voiced by Micheal Bell.
Grogar is an evil Demonic Ram Necromancer and the leader of a kingdom named Tambelon, who once ruled Ponyland with an iron fist 500 years ago before he was defeated when the ancient bell was rung, banishing him and the city to the Shadow World. He then returned to Ponyland 500 years later, capturing all the Unicorn Ponies one by one and plans to capture everyone in Dream Valley to be banished to the Shadow World. He has a cold and antagonistic personality, always scolding Bray for his mistakes and sometimes abuses the Troggles so they can follow his orders and do what he wants.
Grogar's powers come from the bells on his neck, and he has superior magic skills even far beyond any Unicorn Pony that ever existed. Grogar was defeated again by Megan after she rang the ancient bell for the second time, banishing him and the whole city back to the Shadow World.
