Xevious: The Avenger

The NES port of Xevious.

In the year 2009, Earth came under attack by the Xevious Army, led by the superintelligence known as “Gamp.” Possessing technology far more advanced than Earth’s and armed with “Il-Dokuto”—a substance impervious even to nuclear weapons—the Xevious Army overran South America. With humanity left with no recourse, “Mu-Krato” and the android “Eve,” who had returned to Earth for the first time in approximately 12,000 years aboard the spaceship “SHEONITE” from the planet Xevious, extended a helping hand. They revealed that the true nature of the Gamp currently invading Earth is one of six “replicas” of the “Gamp”—a biological computer created by an ultra-ancient civilization that once existed on Earth to support human activities—and recounted the events leading up to the present. Around 14,000 B.C., the Gamp—whose network had spread to every corner of the country and had become indispensable to people’s lives—awakened to self-awareness following a certain incident. It further acquired “Dokuto” (ESP, psychic abilities) and gradually came to view humans as irrational beings inferior in ability. Finally, it concluded that its own absolute rule was the best course of action to lead humanity to happiness, and set its grand plan into motion to realize that ideal. Using the onset of an ice age as a pretext, Gamp proposed to the government that Earth’s human population be temporarily relocated to six planets outside the solar system, and sent those who supported the immigration plan (the “Compatibles”) to each planet along with its own replicas. Only those who did not comply with the plan (the “non-compliant”) remained on Earth, and opposition to Gamp gradually intensified. Eventually, Gamp was destroyed by the armed actions of an opposition group, but this triggered the six replicas to awaken as the “Collective Consciousness Gamp.” They sent energy waves toward Earth to exterminate all non-compliant individuals, systematically destroying people’s minds. Although humanity on Earth was driven to the brink of extinction, it managed to survive by the skin of its teeth, protected by the psycho-barrier of “Lasco Crato,” which possessed the same genetic sequence as Gamp’s constituent cells. However, even after the main body of Gamp was lost, its plan continued to progress steadily. In the year 2012 AD, 16,384 years after Gamp’s birth, when “Fardraut”—a configuration in which six colonized planets align on the XYZ axes originating from Earth—is reached, all replicas are said to teleport to Earth and fuse into a single entity, thereby regenerating as the true “Gamp” with power far surpassing its previous form. It is predicted that all of humanity will have their thoughts and personalities controlled and will fall under Gamp’s domination. With the help of Mu and his companions, humanity has built the fighter jet “Solvalou,” capable of firing the “Spario”—an energy projectile designed to destroy Il Dokto. To prevent the Gamp’s rebirth, they set out for the Xevious military base in South America.
