Morbot

Morbots are only located below Iron Star's surface. They thrive off of the planet's energy, and seem to be feared by the droids. Morbots have never been seen by any robot species on the planet. The morbots are never seen in-game. Later in the game the mils dug down to the morbot layer but they were never seen. The mils later built a space station to find and locate the morbots.
