Nikto is the son of Barada and Klaatu, a pair of alien parents who visit Earth in the episode Invasion of the Turtle Snatchers of the 1987–1996 animated television series.
Nikto beams Donatello and Rocksteady from Earth into the family's spacecraft, first exposing them to illusions until Donatello. He likes playing with the Earthlings, because he think it's fun and they look so weird, despite being told by his parents not to do so.
