Yamato Takeru  

ヤマトタケル, Maxbot

In the 25th century, a spaceship carrying 300 people leaves Earth in search of a new world in the solar system. However, an unexpected accident occurs when they crash into a black hole connected to another universe. The people on the ship are cast adrift in an emergency capsule to a planet called Ismo, which is located in the Onam System, corresponding to our Solar System. The story begins 12 years after their arrival on Ismo. Ismo is the only remaining planet of the Onam System, and it is being threatened by the Death Star Yomi, a comet that regularly approaches the system. There were once eight planets in the Onam System, but many years ago, during the time of the gods, there was a war against an evil monster called Yamatano Orochi (an 8-headed snake-like creature). The gods won the battle and locked Yamatano Orochi into eight stones, one of which is buried deep in the center of each planet. However, Tsukuyomi, an evil god who rules Yomi, managed to reach the stones one after another and destroyed seven of the planets using his powerful robots called Sky Warriors. When he tried to acquire the last stone from Ismo, Susanoo, the most powerful Sky Warrior, got out of control and was blown away. A million years later, Yomi is approaching the Onam System again, and Tsukuyomi plans to take this opportunity to realize his dream of ruling the entire universe by getting hold of the last stone containing Yamatano Orochi. He needs Susanoo to capture the stone, so he sends eight Sky Soldiers to get him back. However, it is too late; Susanoo no longer belongs to Tsukuyomi and now belongs to Takeru, a 13-year-old boy from Earth who discovered the buried robot Susanoo and woke it from its million-year-long sleep. Takeru becomes involved in the battle against the Sky Soldiers and their evil master, Tsukuyomi. Susanoo stands up to protect his friends and their planet.
