In the last few months of Project Loco, the government was getting less enthusiastic about Doc's creations. With limited to no success with integrating them into the public, the gov gave Doc 3 more chances to prove his Locomatons can in fact be life like. So, Doc made the last 3, none of which successful.
The first failed loco went by the name of Pentacle.
Pentacle was designed with a special nervous system. It allows him to take himself apart and be put back together again without feeling pain or needing welding. To finalize this system though, shock treatment was used to properly sync his brain wavelengths to his body wires. However an unforeseen side effect occurred when he apparently lost the ability to speak proper language. Unable to speak, other people assumed he was stupid when in actuality he's quite intelligent.
One night, he ran off. No one knows where to.

How does the name Locomaton sound?
