Pythor P. Chumsworth is the self-proclaimed general and the sole survivor of the Anacondrai tribe. He was sealed away with his brethren in the Anacondrai Tomb after the Serpentine's defeat in the Serpentine War. After being freed, he united his fellow Serpentine and unleashed The Great Devourer on Ninjago. However, the scheme backfired horribly and Pythor became one of the beast's first victims. Long thought to be deceased, Pythor suddenly resurfaced during the Nindroid war, allying with the Digital Overlord to seek revenge on the Ninja. Once again, his schemes were foiled after he was shrunken by a shrinking pill and the Golden Master was destroyed. Afterwards, he was sent to Kryptarium Prison.
The Ninja visited Pythor at the prison after finding out Chen needed him for a spell that would transform his followers into Anacondrai. The cultists ultimately captured Pythor and used him to fulfill the spell. Pythor ultimately escaped and found that the Book of Spells would allow them to summon the spirits of the Anacondrai Generals. After the spell was cast, and Chen's army was vanquished, Arcturus restored Pythor to his original size and he parted ways on understanding terms with the Ninja.
Due to his villainous past, a statue of Pythor was placed in the Ninjago Museum of History. On Day of the Departed, Pythor went to the museum and discovered the Ninjas' old adversaries had been resurrected. He went to the Corridor of Elders and fought Lloyd. After realizing he couldn't win the battle, Pythor fled the scene. His whereabouts are still unknown as he has not appeared since.
