Marinette Dupain-Cheng is a normal girl with a normal life, except she has a secret. She’s Ladybug, the magical superheroine of Paris, and fights crime alongside her partner Chat Noir. Together, the duo protect their hometown from the elusive Hawk Moth, who uses his Akuma to corrupt innocent civilians into fearsome supervillains. When their routine conflict is interrupted, both superhero and supervillain must contend with a mysterious trio: Lord Tartarus, Queen Chrysalis, and Rook.
Meanwhile, a new student begins attending Françoise Dupont, and becomes classmates with Marinette. Is Cozetta Glasgow a normal girl, or is she hiding a secret of her own?
Cozy Glow didn't account for being thrown into this strange world after failing to conquer Equestria. She certainly didn’t account for becoming an entirely different species either! It's a good thing she’s got both Tirek and Chrysalis along for the ride, her bestest friends allies ever! Posing as a family, the trio have identified a potential hot spot for magical phenomenon in their new world. Having to be human isn’t easy for the young pegasus, but it’s not the first time Cozy’s infiltrated a school with sinister intent. No creature in Françoise Dupont will suspect ‘Cozetta Glasgow’, just like the local magical beings will never suspect Rook, her alter-ego in this world of superheroes.
Perhaps she’ll even make ‘friends’ with these superheroes. After all, the best way to defeat Equestria’s always-victorious-heroines is to turn another always-victorious-heroine against them!
Crossover between Friendship is Magic and Miraculous Ladybug. Diverges following Season 9’s ‘The Ending of the End’ of FiM and in between Seasons 2 and 3 for MLB. Spoilers for both series.
