Pim

P.I.M [Pim] aka the Primary Imitation Machine, was created using all-new emotive technology that allows him to mirror expressions. Cogs parent company, Mechano-corp, planned to mass produce P.I.M bots after unveiling their first prototype (Pim) at an expo. However, wire wasn't well-received due to the uncanny valley placing him somewhere between "too robotic to be human and too human to be robotic". Mechano-corp went bankrupt and ceased production of P.I.M bots, shutting down and abandoning all factories. He was sold to the Westfarrow Circus was a permanent display at the freak show and was kept in a glass display tank for well over a year before finally escaping and striking out on cogs own. 

Joined up with Midnight on his adventure, sees them as a parental figure.
