A mid-ranking C Class Hero of America, Tracksuit (only called that because he always showed up in a tracksuit), or Ethan Casey to the very few friends he has, trained by a unique martial arts master turned hobo since his childhood, this man trained him to only use his skill to help. One day, Ethan was called to investigate a mysterious energy spike near his home, only to find anthropomorphic ponies in a crater.

How they got there was because the CMC (this includes Babs Seed) had found a magic crystal growing near their, unfortunately, Silver Spoon and Diamond Tiara found them and began the normal bullying and name-calling that then began leading into a fight breaking out, to where the Mane 6 got involved to separate them, but the magic crystal didn't react too kindly to being tossed around during the fight.

After a magical explosion, the group of mares and fillies get sent to Earth, Ethan takes the group into his apartment, thinking of it as a challenge to take care of something that doesn't threaten all life, but he may be over his head with this self-given mission.
