Biotron II (Earth-616)

The second Biotron Roboid was a duplicate of the original Biotron who had lost his 'life' while serving with the Micronauts. Like his companion Microtron though, this Biotron lacked the accumulated wisdom and personality which the original had developed over centuries spent telepathically linked to Arcturus Rann. Created to serve with the Micronauts on board the HMS Endeavour II, the two roboids never really became a part of the team, and horrified the crew by utilizing technology developed in Baron Karza's Body Banks to heal their injuries. They eventually returned to the ruins of Homeworld.^{[citation needed]}
