Super Robot Wars Original Generation: The Animation

It is two hundred years after the beginning of the Space Era, when human civilization on Earth began expanding into space. However, by the start of the 21st century, two meteors struck the planet, sending humanity into chaos. By the year 179 of the Space Era, secret technology, dubbed Extra-Over Technology, or EOT, was discovered by the Earth Federal Government within a third meteor that hit Earth in the Marquesas Islands of the South Pacific. Dr. Bian Zoldark, head of the EOTI Institute (Extra-Over Technological Investigative Institute), had evidence the creators of the EOT were heading to Earth, in order to reclaim it...or worse, invade the planet. In order to defend humanity from extraterrestrial threats, the government begins to research and develop humanoid mecha called Personal Troopers.

With many of its central personnel lost in the war, the Earth Federation Government is forced to rebuild, and Brian Midcrid, president of the Unified Colonies, takes the position of its president. During an emergency session of the Federation Diet, he publicly acknowledges the existence of extraterrestials, and reveals the events of the L5 campaign to the masses in what will later come to be called the "Tokyo Declaration". He goes on to state that these aliens pose a serious threat to humanity.

10 years ago Dr. Shizuma and his colleagues invented the Shizuma drive which is a revolutionizing new form of renewable and recyclable energy. Though they had to pay a heavy price for their success in a catastrophic accident that the world only wants to forget about. However, all is not well as the secret organization Big Fire is hell-bent on taking over the world. They have obtained two of three mysterious Shizuma drive samples with an unknown function, which are an integral part of their world domination plans. The third sample has however been stolen by Dr. Shizuma who during his escape is saved by Daisaku, Giant Robo and the Experts of Justice. Then a desperate struggle begins between the Experts of Justice and Big Fire for the control of the last sample as Big Fire unleashes their mightiest weapon, the Eye of Volger, upon the unsuspecting world. Soon everything points towards the hidden truth behind the accident 10 years ago as the starting point of everything.

The year is T.C. 4767. Four thousand years have passed since humanity abandoned its birthplace, the planet Earth. Beset by the hostile alien Gnosis, mankind is now scrambling to find ways to defeat this threat to their existence. The development of KOS-MOS (a specialized android with amazing capabilities) by Vector engineer Shion Uzuki was one response to the threat. But when their ship is destroyed by the Gnosis, Shion and her companions find themselves thrust into the middle of a battle with no clear sides...
