Mekenobite

Mekenobites are Luminoth security drones that patroll the corridors of the Sanctuary Fortress, and like all other Luminoth mechanoids, they have gone rogue due to the Ing invasion. The Mekenobite walks on two wiry legs attached to its main body, and they are able to walk on any surface by magnetizing its legs to it. It attacks by firing magnetic pulses, which home in on enemies and explode with incredible force. Its legs are vulnerable to concussive blasts, but it a Mekenobite loses one leg, is can simply regrow it. It can only be destroyed by using Seeker Missiles to destroy both legs at once, causing the robot to fall to its death.
