|This article is about a/an monster in Power Rangers Lightspeed Rescue.|
The rangers faced Mermatron, that resembles a sea creature when they entered the Shadow World. Mermatron is a female and so far has appeared twice only, once in Sorcerer of the Sands and Olympius Unbound. It is unknown if the rangers ever battled her before since she never appeared before those 2 episodes. Her soul was absorbed by Olympius to get out of the Shadow world.
- The wings of Mermatron's costume were later reused in Power Rangers Wild Force for Kired of the Mut-Orgs, who appeared in the episodes "Reinforcements from the Future."
- Her name comes from the Lightspeed Rescue video game, where she also appears.
