Cyber-Fleet (Silver Nemesis)

In 1988, a Cyber-Fleet consisting of thousands of Cyber-Warships came to Earth seeking the Statue of Nemesis. With it, the Cyber-Leader planned to conquer the Earth and make it their base planet as the New Mondas, turning all humans into slaves. When confronted by the Cybermen, the Seventh Doctor surrendered the Nemesis to them and launched the statue on the rocket-sled to meet with the Fleet as the Leader instructed. When the Nemesis reached the fleet in orbit of the Moon, having understood the Cyber-Leader's instructions and disobeying them, it exploded, destroying the entire Cyber-Fleet. (TV: Silver Nemesis)
