The Conductor and Tetsuro attempted to steer the 999 away from the black hole, but was immobilized by tractor beams from Promethium. In the mean time, Maetel was able to escape, and managed to turn off the tractor beams. The 999 was able to change course and returned to the planet to save Maetel. He ran into Mirai, and stopped her trying to kill herself for failing to persuade Tetsuro to become a cyborg. Maetel appeared, and the three agreed to work together to retrieve the pendant from the Queen. Though this time the plan successful and the reactor began to overload, Mirai was killed in the process. Queen Promethium disintegrated (but presumably not killed) in the final confrontation with Maetel and Tetsuro. (thetvdb.com)
