A mysterious race of monsters is attacking Equestria. As Thorax and Pharynx figure out, it’s the kitties the changelings had preyed on. With all love sucked out of them, they have become monstrous shadows of their former selves. And they mistake the ponies for the changelings.
With the Mane 6 down for the count, the reformed changelings must save the day. The kitties are possessed by a literal spirit of hate, seeking to consume everycreature it can. The changelings cannot fight fire with fire. The evil spirit can be defeated only by breaking the cycle of hate.
The changelings are led by Spike, Thorax, Pharynx, and Ocellus. In this case, the Elements of Harmony are not enough (including the Pillars and the Student 6). Instead, love itself must overcome this literal embodiment of hate.
As Spike, Thorax, and Ocellus discover, the changelings must return the stolen love. They figure this out when seeking a path to forgiveness, finding the chance to reach out to a few kitties. Pharynx, meanwhile, must overcome his fear and cynicism.
The kitties are not as bothered by Spike, since he's a dragon. Therefore, Spike manages to advocate for the changelings — explaining how he made friends with them. For the kitties to receive the changelings' love, they must let down their defenses — and so must the changelings.
