Mechander Robot (合身戦隊メカンダーロボ, Gasshin Sentai Mekandā Robo) was an anime series aired in 1977 in Japan. There were 35 episodes aired at 25 minutes each. It is also known as "Gasshin Sentai Mechander Robo", "Mekander", "Mechander", "Combiner Battle Team Mekander Robot", "Combining Squadron Mechander Robo", "Mekander Robot" and "Mekanda".
The robot featured in the series was very massive, three jets combine to dock into the back of Mechander Robo to operate it. Also, the attacks by Mechander Robo done on the monsters were very violent despite the show being aimed at children.
The Doron Empire, hailing from the Ganymede system came to Earth in order to conquer it. General Doron already overthrew the queen Medusa of Ganymede in the Magellan star cluster. Earth's defenses were no match; in a matter of days, 95% of the Earth fell under Doron's occupation. Doctor Shikishima, a brilliant scientist, places his last hopes for Earth in a robot (Mechander Robo) that he has created. The mother of Jimi would be reborn into a cyborg who is now the leader of the opposing forces and her memory could not recall the past. An interesting twist to the usual giant robot formula was that the Doron empire, after having devastated Earth in their successful first strike, ringed it with energy-detecting satellites programmed to lob hugely destructive payloads (similar to H-bombs) on Earth's surface wherever they picked up energy signatures suggesting human technological activity. Having no mean to tackle the alien satellites the Mechander's crew had less than three minutes to successfully engage and beat the invaders' mecha on Earth's surface, before being atomized by the incoming alien bombardment.
