Triskull

Triskull appeared in 2000 TV series called Power Rangers Lightspeed Rescue. Exclusive to the Lost Galaxy/Lightspeed Rescue teamup episode Trakeena's Revenge, Triskull was a Demon warrior who swears allegiance to Trakeena.

He was the leader of the Ghouls, foot soldiers Trakeena uses due to the destruction of her Sting Wingers. Triskull and the Ghouls were freed from the Shadow World, presumably by Trakeena, only to appear in our dimension on Mirinoi. He pretends to aid Olympius in collecting energy for Queen Bansheera, but was actually collecting it so Trakeena can return to her insectoid form. He attempts to stop the Rangers from entering the building, where the energy is kept, and was destroyed by the Red Galaxy and Lightspeed Rangers.
