Greleton is a skeletal Field Commander with a fish skeleton for a gauntlet. He is deployed to fish out the "skeletons" out of humans to rendering them extremely lazy, so much so that they couldn't do much other than lie on the ground, as so to remove any resistance. Greleton, along with a fleet of X-Borgs & Bruisers, arrived in Roswell, New Mexico, where Gia & Emma met Mawrg. He was defeated by the combined forces of Super Megaforce Yellow, Super Megaforce Pink.
