TD-01 (Tech Droid 01) was the first out of the many first made droids to be sent on research and scouting missions with the senate. Unfortunately within the process of this creation, there were some heavy tolls taken since the droids seemed to lose quality after some time. But 01 was the only one of his kind to survive as long as he had and still in great condition. He later gained sentience and when the senator he was assigned to gets murdered by the separatists he flees and goes into hiding. As he hid in the planet of Wobany he was found by two clone commandos, Darman and scorch. He was confused but with them explaining that they can give 01 a place to stay and be able to serve under them he agreed and became part of the clone rebellion
