The CPU is easily the most mean of spirit, cruel and generally unpleasant robot in MonsTECA. Fortunately there is only one of him. He commands all the Robot forces, and plans their every move.
The CPUs have succeeded in line through the passing down of the same chip that was placed (by the Maker) in the very first Robot all those years ago.
He controls all of the Robots but he is gradually experiencing more breakdowns, crashes and glitches etc. mainly in his logic and understanding functions.
He proved incompatible with his chosen compatible unit and she left him with a 2nd unit daughter Eugenie who he struggles to relate to due to her over-caring un-Robot-like nature.
