It is the final battle, and Grogar has found out about the Legion of Dooms plan to overthrow him, and has taken his bell back from them. Now he plans to fight and destroy Twilight Sparkle himself. however one of the young 6 has a plan that he least expects.

Idea was based off the Antman meme that came out before Avengers End game. Also note, this was thought of before the series finale, so I understand that this doesn't make sense for those who have seen it. However I still don't think it would classify as something completely "Alternate Universe."
