Galaxy Express 999

Planet number one, Zaba, and plane number four, Maya, are engaged in a war to the death. Though they knew nearby planet number five was about to blow up, the 999 had to make a critical stop on planet number three. Upon exiting the train, Maetel and Tetsuro are attacked by a mysterious ape-man and their passes are stolen. While researching the planet, they meet a boy from planet number one, Seth. He came with his girlfriend from Zaba, which was on the verge of destruction. They plan to stop the mysterious degeneration on planet number three to create a new Zaba.
