Well, here it is everybody, the final season of "My Little Pony: Friendship Is Magic", one of the most popular things that we as humans have ever created. Here we get to see a new villain called Grogar summon the other My Little Pony villains. We get King Sombra, Queen Chrysalis, Tirek, and Cozy Heart gathered together. What's great is that everybody stays in character. King Sombra wants to go back and conquer the Crystal Empire on his own. He actually does seem to do that! I just love how fast paced everything is in this episode! There's also the other plot about Princess Celestia and Princess Luna giving up their ruling title to Twilight and her friends. I would like to see if they inherit their powers too. The animation is probably the best it's ever been at. Only appropriate for the final season. Thanks for the memories!
