The Pyro Destroyers are members of the Pyro Vipers. They are villains in the Season 11: Secrets of the Forbidden Spinjitzu. They are ancient Serpentine and served Mambo the Fifth until Aspheera stole the throne using Spinjitzu (which Wu taught her as part of a deal). The Pyro Vipers eventually died out and several mummies of them found their way into museums and tombs where Aspheera used magic to awaken them as mummies under her control. The Pyro Destoyers help Aspheera during the Fire Chapter along with Char, the Pyro Slayers, and the Pyro Whippers.
The Ninja found several deceased mummies of them in coffins In the Ancient Pyramid. When lava rushed into the room they were resurrected as undead mummies. The Ninja fought them and managed to escape. It is unknown what happened to them after the pyramid's destruction.
They traveled with Aspheera and fought the Ninja.
Legions of them attack the Monastery.
They try to enter the gate to the Underground Base.
