I'm a huge fan of, in no particular order, Transformers, Warhammer 40K, My Little Pony, and Bionicle. I also ship Optimus Prime with Princess Celestia (my favorite pony), and Tahu with Rainbow Dash
After the Decepticons discover energon on a distant planet, Optimus Prime and the Autobots arrive in Ponyville, quickly attracting the crown's attention. Now it is up to Prime and the princesses to protect Equestria from the Decepticons.
