Mechander Robot - S01

The Doron Empire from the Ganymede System found Earth and saw it as the perfect world to conquer. Their push to expand came from the power-hungry General Ozmel, who overthrew Queen Medusa, the reigning ruler of the Ganymede System, as the first step in their universal conquest. Earth has almost completely fallen to the empire and is in its final days. One scientist, Dr. Shikishima, has only one hope for freeing Earth from its alien conquerors: a massive mecha called the Mechander Robo, specially programmed and designed to fight the invading aliens and stop them from taking over Earth completely. Along with this powerful fighting machine, Dr. Shikishima recruited three pilots to sit behind the Mechander Robo's controls: the mysterious Jimmy Orion, the scientist's son Ryosuke Shikishima, and Kojiro Hachijima. Although the main story is about Earth battling the Doron Empire, something in lead pilot Jimmy Orion's past is somewhat connected to the entire storyline.
