Twilight, Sonic, Sunny and friends have returned for new adventures. Eggman may be gone for a while, but a new threat will rise. And there are a lot of things going to happen this season.
Time and space are very fragile things. The Mane 6 and the Freedom Fighters are going to learn that the hard way. There are much worse things they're gonna face when it comes to time and space. Whether it's past, present or future.
The continuation story of the entire continent containing Equestria and beyond being on Earth, and they go on new adventures with what's left of the Freedom Fighters, since there is no need for them to fight for something they now have.
The entire country of Equestria and small section outside of the border have been sent to an entirely different world, and every creature was given a form in between human and what species they are. Even meet some new friends on their adventure.
Two gamers, once oblivious humans who ejoyied playing online together, now find themselves in a world completely unlike the one they were raised in. Now they are also completely transformed into creatures that are strangely familiar to them.
After Sonic rescues Knothole from Dr. Eggman after a brutal defeat, he and several other Freedom Fighters are thrown through the multiverse to a land that is inhabited by quadripedal ponies and where chaos is absent, for the most part at least.
