Dr. Mindbender has been interested in Tony Stark's designs long before the latter became the avenging Iron Man. Back when Tony was just a whiz kid at MIT he took 1st place in the school's 4th Annual Robot Design competition. Mindbender was intrigued by Stark's combination of heavy duty manufacturing robotics with behavioral machine learning intelligence. What Tony mistakenly mistook as flaws in his protoypes' object recognition processing, Mindbender knew to be a lack of supplied information for the machines to make the necessary mental leap. Mindbender reverse engineered the Stark Arm and created a more elaborate positronic matrix capable of learning and guessing next variables with minimal dataset input. When the project proved to be a success he used that same programming and hardware for the Cobra Battle Android Troopers. The DUM-E arm now serves as foreman for the BAT Factory where it oversees the manufacturing of new BATS.
