Kryptonita (transl. Kryptonite) is a 2015 Argentine action drama fantasy film co-written and directed by Nicanor Loreti and starring Pablo Rago, Lautaro Delgado, Juan Palomino and Diego Capusotto and based on the novel of the same name by Leonardo Oyola. The story uses Elseworlds' famous structure of alternative stories to adapt DC's Justice League superheroes to a suburban setting in Argentina, where Superman and his team are a gang with a low class background battling a corrupt police force and local versions of Doomsday and the Joker. It was officially released in the 2015 edition of the Mar del Plata International Film Festival.

After the success of the film, it was announced that the story would be adapted as a TV series sequel for the Argentine cable television channel Space. The series is titled Nafta Super and it premiered on November 16 of 2016. Nafta Super is a direct sequel to the film, picking up a few months after the story for Kryptonita ended, and with most of the original cast returning for a total of eight episodes.
