MK Ultra Girls was a scrapped children's cartoon based on the Mortal Kombat franchise being produced at Warner Bros. Animation around 2020, which would have revolved around aged-down versions of Mortal Kombat characters going to school. The character designs were done by YouTuber Pan-Pizza and the series got very far into production, but was scrapped after a change in leadership at Warner Bros. Animation. Alongside an action figure line, an iOS game based on the engine of Mortal Kombat X Mobile was planned. According to the Redditor who originally leaked the show's existence, NetherRealm "did okay getting these designs in 3D but it's far from done. Progress has halted on the game which is also effecting [sic] the show."
