Praygat

Praygat was a Tritovore trader.

Biography
He came with his collegue Sorvin to trade with San Helios for dung to feed on. However their ship was grounded by the Stingrays and they were marooned on San Helios after it was destroyed. Some time later they saw the Number 200 bus arrive through a wormhole and brought the Tenth Doctor and Christina de Souza to their ship at gunpoint. They assumed they were responsible for the attack on San Helios and planned to kill them. However the Doctor soon proved them wrong and they soon gathered enough equipment to take the bus back through the wormhole. He offered them passage to Earth, where they might find a home. Praygat and Sorvin agreed but were killed when one of the Stingrays burst through the ceiling and devoured them.

Behind the scenes

 * Praygat was not named on screen, only in the credits.
 * It is not known which one of the Tritovores was Praygat. Paul Kasey states in DWM that his character, Sorvin, had a few scenes in the desert, which leads us to believe that Sorvin was the Tritovore who took The Doctor and Christina to the ship.
