Serot is an asteroid located in Dimension X in the 1987 TV series, home to some slave pits that were run by Vorx. It was also the location of the pit of the Great Chaarg, which in practice served as a death penalty for rebelling slaves attempting to escape. The Ninja Turtles were taken there after being sent by Shredder to Dimension X in the "Shredder Triumphant!" episode.
