Catalyx

Catalyx is a being of unknown origins who served on the Enterprise. He is a skilled pilot. After Naju hijacked the Enterprise, he was left floating in space, due to the explosive decompression on the bridge. He eventually crashed into Chenrotoss, and died. His life essence created the Toa Catastras.

His remains were eventually recovered and left in a junkyard, where they remained for thousands of years until being found by Mirage,Evelin, Nemesis, and Barnax. They were able to reassemble Catalyx and bring him back to life, but as a result of the damage he'd incurred during his death and his finders' inexperience with robotics, he was left amnesiac, and Barnax uploaded a standard battle-droid software package to his brain.
