This day seemed to be just another visit on Equestria to check if Ocellus was doing well in Twilight's school for Pharynx and Thorax. And it was normal for most of it, until they came across a creature that came from the sky, while they were coming back to the Hive.

At first this creature that happened to be named Aegis, seemed safe to be around and it made them stay with him for the night, but things got worse the morning after when Aegis stunned them both and took them inside his ship and took them both to a planet called Sakaar.

After two weeks of being on that planet, there seems that there is no a way out of this planet.

However, they get a chance to escape and return to the Hive, when a man who calls himself "God of Thunder" comes into the picture.

But it only gets them involed into something that they (especially Thorax) would like to avoid. In exchange for getting back to their home, they must help him save Asgard from his sister Hela.

I suck at summaries. I promise that I will change it once I'll came up with a better one. Same thing with the title.
