Kulminator is Dr. K's second most powerful robot (behind Kilobot). It was once Dr. K's HQ as a giant advertisement tower in an abandoned area of Bubble Town. After Dr. K had gathered enough Solex, he used it to create a humongous EPU which transformed his HQ into a giant four-legged robot. Dr. K piloted it on a course for Bubble Town with intentions to destroy it. The Botties (piloting Krab, Katastrophe, Klawber, and Kannon) attempted to stop it, but it was too big. The Alien then used the Kulminator's ultimate weapon, the Solex Blaster, to destroy Cubix, but he absorbed the energy and then fired a Solex blast of his own, knocking out the Kulminator's shields. Dr. K wanted to retreat, but the Alien was determined to continue, firing the Solex Blaster at everything while Dr. K abandoned ship. Cubix then flung himself into Kulminator, striking its EPU, destroying it and the Alien. It appeared in 'Cubix the Movie: The Search For Solex' and in season 1 Episode 13 ' The Unbeatable Robot '. It also appeared in The Fight for the Fox Box in a redubbing of the aforementioned fight.
