Biotron was constructed at a Yomi Factory on Micropolis-10 for use by the Ministry of Science. After his pilot died, he was left in a storeroom on Valtricos Research Station, dormant but still activate. He was still able to monitor the Ministries activities, including the destruction of Biotrons on Saqqura by the Entropy Cloud.
Four years later, Ministry of Defense.Biotron was found by the Micronauts when they were hired to retrieve what they thought was medical supplies from Valcitros. Oz accessed the robot’s systems, learning that Valtricos was not a medical facility, but a laboratory developing biological weapons. They were soon attacked by the
