The Garthim are robust armored creatures which serve as guards and soldiers to their masters, the Skeksis. Their appearance is reminiscent of a huge beetle or land crab. The first member of the species was created by skekTek the Scientist, by combining parts from the corpses of a Gruenak and an Arathim. Being an artificially-created race, the Garthim have no will of their own, and live only to serve the Skeksis. After the destruction of their masters, the Garthim bodies simply fall apart, revealing a hollowed interior.
