GEAR Senshi Dendoh

Several hundred years in the future, the resources of the Earth runs out, and the progression of the human race has stagnated. The world is now divided into "Units". A boy named Hajiki Sanada lives with his mother and sister in Unit 74, in a place called "Night Town", in which all electricity is shut down at midnight. The key in this story is an object called the GAD. GADs have the ability to reconstruct materials while reacting to feelings of an organic life. The size and shape of the resulting product seem to be different depending on the kinds of feelings that the life possesses. When Hajiki comes in contact with one by accident, it transforms into a huge robot--a Tekkoudo, or "Iron Giant"--which Hajiki names Lightning. And soon he realizes that he isn't the only one with a Tekkoudo, and must find out how to deal with those others who he feels are the "same" as himself.

The Doron Empire from the Ganymede System discovered Earth as an ideal world for them to conquer. The interest of expanding the empire came as a result of the power-hungry General Ozmel who overthrew the current reigning Queen Medusa of the Ganymede System as a start of their universal conquest. Almost completely succumbed to the empire, Earth is at its last days, and one scientist, Dr. Shikishima, had only one hope in restoring Earth from its alien conquerors--- a massive mecha known as the Mechander Robo, specially programmed and designed to battle these invading aliens from complete takeover of Earth. Along with this awesome fighter machine, Dr. Shikishima also recruited three pilots to be placed behind the Mechander Robo's controls--- the mysterious Jimmy Orion, the scientist's son Ryosuke Shikishima, and Kojiro Hachijima. Although the primary storyline is Earth battling the Doron Empire, there is something within lead pliot Jimmy Orion's past that was somewhat connected towards the entire storyline.

In the year 2005, a race of alien monsters called Zonders emerge from underground and launch a series of attacks on the city of Tokyo. The only defense against these creatures is the secret agency known as the Gutsy Geoid Guard (or 3G) and their ultimate weapon, the awesome giant robot GaoGaiGar. GaoGaiGar's pilot, Guy Shishio, is a former astronaut who was nearly killed two years before when the Zonders first crashed to earth. Guy's life was spared when a mysterious robot lion called Galeon pulled him from the burning shuttle and brought him to Earth. Guy's father, Leo, then used Galeon's technology to rebuild his shattered son as a cyborg, in the hopes that he could stop the aliens when they appear. Now, with Galeon as its core, GaoGaiGar fights to protect Earth. He is aided by a team of transforming robots and by a young boy named Mamoru, who has the power to purify the Zonders' cores, and seems to be connected to the mysterious Galeon.

A huge space monster appeared in a city and began to destroy the city. People were escaping with screaming. Among them, there were five high school students, En, Kai, Shin, Yoku, and Ryu. However, they failed to escape, and they rushed into a patrol car parked nearby. The monster was approaching to them. When they began to accept their death, the patrol car glowed blue white and disappeared into a mysterious space carrying them. When they were astonished, it was an alien that appeared in front of them. He was a Bravian who is an officer of the Space Police Organization that was responsible for the peace and order of the universe. He explained them that he was aimed at by ferocious aliens in the Space Prison Sargasso. He added that he had given them a battle machine "Dag Beagle" made by copying machines on the Earth in order to fight against Sargasso. They turned into Dagwon by the power of Bravian, and fought against space monsters. At that moment, the patrol car came in front of En. En grew into the car and turned into the Brave Robot Dag Fire, then beaten the enemy. However, the fight between the Brave Dagwon and the felonious aliens of Sargasso had just begun.
