This story is a sequel to Equestriatale: The Other Side

The first season of an Equestriatale series. Monsters and ponies together in Equestria. What could possibly go wrong? A lot actually. From miscast spells to giant Equestrian beasts to other hilarious hijinks, there's a lot that goes on in the lives of ponies and monsters.

Deep in the Ever free Forest, a cave can be found. In that cave, a bright barrier prevents any progress forward. Beyond that barrier is an entire civilization of monsters. When the human Frisk helps shatter the barrier, the monsters emerge and eventually become friends with the ponies of Equestria. Soon after, weird glitches begin, eventually escalating to the point of causing ponies and monsters alike to vanish. A group of ponies and monsters, led by Twilight Sparkle, King Asgore, and Frisk, attempt to locate the source of the glitches and restore the world.

Ever since the Doctor met Minuette, she's been calling him constantly, interested in the fact that they share the same cutie mark. One day, the Doctor prepares his TARDIS for his monthly trip to Gallopfrey when Minuette arrives. She forces her way into the TARDIS and refuses to leave, so the Doctor lets her tag along.

When an old foe arrives in Equestria and threatens to erase the current timeline, The Doctor must gather new allies and travel back in time to fix the damage to the timeline before everything he knows disappears forever.
