If you are reading this, then I welcome you to my most ambitious project - a whole saga on the extremely popular (in Japan) video game series Super Robot Taisen. which brings together mecha from all kinds of anime, and spins a whole new story to tie them all together. It's a really great series, especially the newest ones like Z and the episodes for portable consoles, so if you ever get a chance, give them a try!

In particular, this one takes inspiration from Super Robot Taisen R from the Game Boy Advance, though it definitely won't be a copy-and-paste of the story. As you will see, there are some new series, and new elements will be introduced, so I hope I'll be able to deliver a good story and amuse all the fans of this awesome series of games!

That said, I should leave you to reading the beginning of my story! Enjoy!

And excuse the mistakes I might make... English is not my native language! *giggles*

Chapter 01 - Prologue

Progress. Knowledge. Ambition. These are the operative words when talking bout human evolution. Since ancient times, man always wanted to understand and control his surroundings. Unique among all the living beings on Earth, mankind was able to develop the intelligence needed to not only adapt to the surrounding environment, but to also adapt the environment itself to itself. This has been a constant in the long history of mankind... and now, it has allowed humanity to spread into space and begin exploring new horizons.

More than one century went by since humanity began leaving the over-populated Earth and created space colonies: huge satellites in which mankind was able to recreate the living conditions present on Earth, allowing the survival and reproduction of plants and animals, and creating huge space cities who prosper thanks to these resources. New cities were built on the surfaces of the Moon and Mars, paving the road to further progress.

Unfortunately, when speaking of human history, we cannot leave out another crucial constant.

War. The desire to fight, destroy, overcome others. An instinct also common to animals, and an instinct of which mankind, despite its superior intelligence and resources, was still unable to get rid. Technologic and scientific progress, unfortunately, also has its negative side: in fact, all these new abilities have often been turned to serve mankind's most primal instincts, spreading death and suffering on an ever-expanding scale. Even in the future, even in the space colonies era, this tendency has remained.

The old, weak and corrupt Earth Federation considered the colonies' inhabitants as second-class citizens, depriving them of many resources and forcing them to submit to its will to survive. This situation degenerated with time, and the battles for the colonies' independence become more and more violent... until the Side 3 colonies, united under the name of Principality of Zeon, declared themselves independent, starting what would later be known as the devastating One Year War. To further aggravate the situation, another arbitrary distinction among human beings intervened - on one side, the Coordinators, genetically enhanced human beings; and on the other, the natural-born Naturals. These two "factions" looked to each other with mixed feelings of suspect, fear and envy, thickening the already-present tension... and the fact that, only ten years before, the Earth had been savagely attacked by mysterious being known as Heterodynes, leaving the planet in serious need of recovery, only worsened the situation.

The fighting between Earthnoids and Spacenoids, between Coordinators and Naturals, did not end with the war, and continued with numerous colonial riots and terroristic operations, chief among which the so-called Operation Stardust, in which a group of Zeon remnants stole the Gundam GP-02A Physalis, a top secret Federation Mobile Suit prototype, and managed to hijack an empty colony and drop it on Earth, causing serious damage to the planet's ecosystems. Following this incidents, the Titans and the Specials division (aka OZ) were founded - the former, an anti-Spacenoid suppression force, noted for its brutal and ruthless methods; and the latter, the military branch of the warmongering Romefeller Foundation. To add to that, numerous government organizations were born with the objective to put a stop to genetic engeneering and halt Coordinator progress... chief among those, a fanatical environmentalist group known as Blue Cosmos, whose leaders maintained that Coordinators had to be ostracized and exterminated to "preserve a blue and pure world" and to safeguard humankind' genetic heritage.

Needless to say, such actions could only exacerbate tensions... and following two extremely tragic accidents (the Titans' complete extermination through nervine gas of a dissident colony, and the destruction of a PLANT through nuclear warheads - which would later be known as Bloody Valentine Tragedy for the fact that it happened on the 14th of February) which cost Spacenoids more than half a million victims, several rebellious organization were born, among which the Anti Earth United Government (A.E.U.G.), the Zodiac Alliance of Freedom Treaty (ZAFT) and the more sinister White Fang. War broke out, only ending when the Titans, Romefeller Foundation and White Fang were destroyed along with ther leaders. Exhausted by the continuous wars, Earthnoids and Spacenoids embraced the ideals of Total Pacifism, allowing the Federation to be reborn as the Earth Union. Blue Cosmos, which had manipulated events from the shadows, was forced into hiding, and ZAFT momentarily ceased hostilities. Human beings had finally ceased fighting amongst themselves...

Alas, this was not to last. As if waiting for the right time, numerous alien invaders tried to take advantage of the reduction of military resources to attack the near-defenceless Earth Union. Mikene Empire, the robotic entities known as Gulfer, the faceless monsters known as Zeravire, the cyborg invaders called Meganoids, mysterious aliens only known as Jovian Lizards, and the forces of the allied planets Cambell and Boazan. At the same time, the Principality of Zeon was reborn as Neo Zeon on the minerary asteroid of Axis, and started an aggressive expansion campaign... and the lunar colonies, joined under the banner of Giganos Empire, declared war on the Union, calling for a new order under the "enlightened" guidance of the spaceborn generation. Such a disastrous set of invasions was only stemmed thanks to the intervention of powerful "Super Robots": Mazinger Z, Great Mazinger, Getter Robo, Gear Fighter Dendoh, Daitarn 3, Gravion and others...

ZAFT, led by the radical Patrick Zala, had opened ostilities once again, by hijacking four powerful Gundam-type Mobile suit. This event was only part of a criminal plan to exerminate the Naturals, and only the courage and tenacity of several Union aces, such as the Newtype pilots Amuro Rei, Kamille Vidan, Judau Ashta, and of the crew of the warships Archangel, Idaho and Nadesico managed to avert disaster. But the net result was, that the peace everyone was calling for had been shown to be nothing more than an illusion.

Bitter criticism was levelled towards Total Pacifism, and a devastating coup collapsed the Earth Union and marked the birth of the New Earth Federation, under Chairman Dekim Barton. Relationships with Spacenoids, that had been more friendly during the time of the Earth Union, degenerated once again, and new hostilities started between the New Federation and the second Neo Zeon uprising, under the guidance of the infamous Colonel Char Aznable. As if this wasn't enough, ZAFT was attacking once again, and Blue Cosmos was coming out of hiding, backed up by the shadowy LOGOS...

Space Century, Year 141. Five years after Dekim Barton's coup, in a faraway lunar base, the final test runs of a new weapon were about to start... a weapon destined to have a huge impact on humanity's blind rush towards self-destruction...
