The Bohrok are mechanical insectoid creatures, controlled by strange parasitic beings that live within their heads, known as Krana. If a Bohrok loses its Krana, it shuts down and can be reprogrammed to do one's bidding; but if a Krana gets on another being's face, it then assimilates its host into the swarm. The Krana, which control the Bohrok, are in turn controlled by the two fearsome Bahrag, twin queens of the swarms.
