The Robot death Tournament series, is a worldwide martial arts competition, where many different robot fighters from around the globe, each with his or her own unique fighting ability, come together to engage in a life-or-death struggle, to earn the title as the #1 fighting champion of the world. The Robot death Tournament is sponsored once a year by the National Association of Robotics and AI (NA Robotics) and the Robot/AI Martial Arts Association, along with co-sponsors from The World Robot Superheroes and United Robots. With this tournament, Na Robotics draws in the world's greatest fighters in order to obtain combat data for a project to create the ultimate combat weapon, robot military soldiers. Each contestant is specialized in a particular skill, and they are pitted against each other in a martial death match. Both group fighting and individual fighting with combinations and permutations of superpowers are marshaled into the arena to test the combatants’ cognition and physical prowess (Part 4).
