Pythor P. Chumsworth is a Ninjago minifigure and the main antagonist of the show's first season as well as the secondary antagonist of the show's 3rd season, and a supporting protagonist in the 4th season. He is the last surviving member of the Anacondrai Serpentine tribe in the theme. Although presumed to be killed in the Season 1 finale, Pythor returns as the secondary antagonist in Season 3, but becomes a hero in Season 4. Pythor is presumably scheduled to return in season 7 due to his inclusion as a Minifigure in the set 70596 Samurai X Cave Chaos.
