Coby Hansen, with his brother Bud, and their friend Lori, live in rural Colorado. Although he is only a teenager, he assists the Autobots in the search for the Cyber Planet Keys and the fight to save Cybertron from the devastating Unicron Singularity.
Although Coby has his faults - Lori would be quick to point them out - two of his finest qualities are his concern for his family and friends (especially Bud), and his outstanding mechanical aptitude. Armed with only a few tools and general references, Coby was able to quickly comprehend the alien workings of a Transformer's internal systems, and repair the damaged Landmine, through whom the young mechanic and his friends became acquainted with the Autobots... and, all too soon, with the Decepticons.
HE can even retrodesign a Scrapmetal to fit a human pilot for control that has no offical name but for reason, (un)known it was dubbed the Cobybot which he pilots for more information go to the links.

He also fixes up the 'bots when they're broken and is generally scolded at and fussed over by Lori for some crazy reason nobody can possibly guess.
