In my headcannon, the MLP ones meet a version of Selina Kyle. African-Asian on her mother’s side, and American with Russian descent on her father’s. A vigilante who stole from rich rogues to help the oppressed. Very into animals. Very sassy yet sweet. Able with martial arts from Japan, China, Korea, Egypt, India, Thailand, France, Greece, Indonesia, and Israel. Her strength, speed, agility, endurance, stamina, and senses enhance by cat essence similar to Halle Berry’s version. And the girlfriend and eventual wife for Bruce Wayne. And instant pals with Rainbow, Fluttershy, Pinkie, the CMC, Fizzlepop Berrytwist, Moojdancer, Minuette, Bon-Bon, Lyra, Rara, Daring Do, Derpy, Doctor Hooves, Luna, Windy Whistles, Bow Hothoof,Soarin, Dyscord, Flurry Heart, Cadance, the Young 6, and Somnabola. Some such as Twylight, Rarity, Applejack, Celestia, Shining Armour, Bigb Mac, Starlight, Trixie, and Spitfire presume her a rogue; only forthwith prejudice and doubt to help the Penguin receive them to use them against Batman.
