Leather Bug is a flea-like monster who tries to find a heat source for Lord Geric's weapon. Leather Bug can absorb the heat from people & locations, using the absorbers on the palms of his hands. This process will turn the people into frozen shells & the locations into frozen wastelands. Though he doesn't wield a weapon, he can blast flamethrowers from the heat absorbers. He is killed by the Red Dragon Thunderzord after being thrashed by the other Thunderzords, including the Lion Thunderzord's claw attack.
