Story
Zul is the cruel and mysterious ruler of the planet Gishin. The people of Earth began exploring space Beyond the solar system and Zul, who aims to conquer the galaxy, sees this expansion as a threat to his goal.

He targets Earth for elimination and to do this, he sends a male baby called Mars to live among humanity. Accompanying the baby is a giant robot named Gaia, which contains a new powerful bomb strong enough to destroy an entire planet. As planned, Mars is expected to grow up, where he will activate the bomb within Gaia to fulfill the mission of destroying the Earth. However, when Mars arrives on Earth he is adopted into a Japanese family and given the name Takeru. Seventeen years later, Takeru grows up with a love for humanity and refuses to detonate the bomb as ordered by Zul. However, if Takeru was to die, the bomb within Gaia would explode destroying the earth.

Unknown to Zul, five other robots were created in secrecy alongside Gaia by Takeru's real father and sent with Gaia to protect Takeru. Whenever Earth is in danger, Takeru is able to summon the five other robots to combine with Gaia to form the giant robot God Mars. The five other robots are Sphinx, Uranus, Titan, Shin and Ra.

It is eventually revealed that Zul is actually a god of the afterlife and that his physical body is only a shell that can be recreated by spreading his cells all over the galaxy.

In the last episodes, a Group of masked aliens called the Gestalts are actually fragments of Emperor Zul and in the final battle, they fuse together to recreate Zul, however, he is defeated for good by God Mars.
