Complete Monster: Kilobot is the Dragon-in-Chief to Dr. K, the Arch-Enemy of Cubix, and the most vicious character in the series. A Power Parasite, Kilobot regularly drains innocent robots' life-energy throughout the series, plunging them into death-like comas in the process. When acting on orders from Dr. K, Kilobot goes out of his way to cause more destruction than remotely necessary, often times targeting children and innocents for fun. Kilobot regularly defies his master's orders, trying to let a weather machine destroy an entire city, stealing a cloning device from a robotics corporation, framing a hero for it, then trying to blow up said corporation when discovered, and murdering Dr. K's best friend, all on his own accord. Betraying Dr. K, Kilobot executes Maximix, takes control of an army of Zombots, then plans to use them to turn every robot into his slave then Take Over the World, and, when his plans are thwarted, Kilobot makes one last attempt on Cubix's life by crushing his power core in his bare hands. Though appearing in a lighthearted series, Kilobot was a depraved monster whose appearances darkened the series considerably.
