A Nighlok that serves Serrator. Pestilox assisted Serrator in his plan in taking over both Earth and the Netherworld by placing the final wedge that can cause the Sanzu River to flood the Earth. Pestilox had a swarm of flies that caused stomach pain on everyone if they swallowed them and can also emit tentacles. When Pestilox's troubles was interrupted by Serrator who attacks the Rangers, Pestilox attempted to escape as Jayden, Mia, and Emily pursue him. Pestilox is defeated by Jayden's Bullzooka causing the stomach pains on the humans to be undone. When Pestilox grows, Jayden, Mia, and Emily used the Samurai Megazord to battle with Pestilox. Mia used the Beetle Disc to form the Beetle Blaster Megazord and Emily used the Swordfish Disc to form the Swordfish Fencer Megazord to battle Pestilox, the Giant Moogers, and the Giant Spitfangs. After finding out that even the Tiger Drill Megazord nor the BattleWing Megazord would work in combat, the Rangers form the Claw Armor Megazord to weaken Pestilox. They then slay Pestilox with the Shogun Cannon Blast finesher of the Samurai Battle Cannon.

Pestilox's body looks very similar to a male human's private parts, so it is unknown how the producers on Power Rangers had him adapted.
