After the Doctor escapes with his life after fighting off a group of Sontarans, the Doctor's age starts to get to him, and his regeneration will soon begin. As The Doctor's Regeneration is complete, she is then found by a girl named Sunset Shimmer, who found her unconscious and sent her to the Canterlot High medical room. And when she looks in a mirror, she sees, to her horror, that she's...young and a little nerdy.

Now, The Doctor and her new friends must fight off an invasion fleet of Cybermen, who are hell-bent on terraforming Earth into Mondas.

These are the adventures of the Sci-Twi Doctor/The EQG 2nd Doctor.
