Garthim

Garthim appeared in 1982 movie called The Dark Crystal. 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, and they appear to be artificially created, since after the destruction of their masters the Garthim bodies simply fall apart, revealing a hollowed interior. It is possible that they represent the remains of some creature drained of its life essence to serve the Skeksis, but their true origins are not known.
