Koppo

History.
Koppo was made when Mighty and Amy sprung into being, when the Moon smashed into the neighboring planet, Sonni, a nuclear planet, and formed the moon that Koppo has, Lunaria. Mighty and Amy, from Lunaria used their Rock and Earth Powers, and Sun and Moon used their powers to create life on the planet, so in a few hundred Billion years they could return, and strip it of life. They got a species from their collection, and made it live on earth, called humans. But, the Nuclear from Sonni was still on Lunaria, so Mighty and Amy decided to get rid of it, and dump it on Koppo. However, there was so little left that there were only 3 Rivers worth left, and they became monsters. They sent Gleem to control the planet, until it would be destroyed. however Gleem felt pity knowing that they would be destoryed, with out being taken back so he turned into Star with out Sun and Moon knowing. Then, after saving the planet from the Monster King, who was the first monster they found Sun and Moon and beat them, and star (who had sealed his own memory) Fought Sun and Moon to save Koppo and Regained his own memory.
