Formerly: X-O Mecha Class Armor Rai (霊, rei, "spirit") is a fictional superhero that appeared in books published by Valiant Comics.

The crossover "Malev War" plot of the second volume largely involves Rai creating and leading the Future Force, a team made of several superheroes from different parts of the Valiant Universe, such as Magnus the Robot Fighter, and Gilad the Eternal Warrior.

To house and feed its growing population, the country had built upon its own infrastructure centuries before, turning the whole of Japan into a towering pillar, hundreds of miles wide.

While the higher classes of Japanese society rely on advanced technology, including sophisticated, human-looking robots-or PT's for Positronic Minds-on every level of their daily lives, discontent has brewed for centuries on Japan's middle and lower levels, resulting in the formation of an extremist anti-technology sect called Raddies, who have vowed to overthrow Father and every symbol of his technologically enabled reign.

Standing solitary guard at the top of Japan's miles-high structure is Rai-the lead enforcer of Father's justice and a figure of near-mythic stature to Japanese citizens of all ages.

But few have ever seen him...until the first murder in nearly a millennium brings Rai to the forgotten sectors of Father's empire, and threatens to topple a Japan that has taken nearly two thousand years to erect.

[3] Over the course of his investigation Rai X would come in contact with the mysterious Spylocke, a rebel rousing super agent who is normally relevated to holo-vid projections for the entertainment value of the masses.

Eventually he meets and falls in love with a recently companion-less Positronic A.I (PT) named Momo, who was among many of her synthetic kind to gain awareness of herself and her social situation.

Joining their shared cause is fellow outcast and renegade experiment Izak, a hybrid blend of Father's livewire and long extinct alien genetic material fished from amongst the stars; his new race was meant to be a proceeding protectorate task force for the floating city but were too volatile and bloodthirsty to ever be controlled, therefore being cast down to Earth with only him escaping.

Silk, a long time resident of New Japan and greatest if not most conniving scientific mind of the 41st century, Rai managed to stall an all out war between Momo's faction of self-aware Positrons and the anti-father/PT terrorist cell known as the Raddies, which would serve to further the despotic rule of the A.I.

Meanwhile, back on New Japan Rai's friends and fellow revolutionaries have either been driven underground (as many are in hiding) or have been captured for interrogation and participation in bloodsports as a means of execution.

Even coming across new allies and enemies along his trek across the wastes in order to find a way back home, most notably Lemur; a resident of the burning earth who can sense a person's moral fiber, whose home was burned by the dead world christened "Always Rising Sun" due to its constant solar waste dumping upon the world.

But only Rai knows they're pieces of New Japan that are being jettisoned to earth by Father, in an effort to purge his systems of a computer virus the late Spylocke and a wounded Lula cast into his core processor.

Rai, Gilad and Lemur eventually find themselves within a cave harboring a long thought lost ancient weapon created by man, an old X-O Armor Mecha Class which was left over from the war that engulfed the earth just as New Japan ascended to the skies.

Early in the 31st century, the entire land mass of the island nation of Japan was blanketed by hundreds of levels of high-tech urban sprawl.

In order to support such a spectacular megalopolis and its population, a tremendously powerful central computer was designed to control every aspect of the island's function.

But in its darkest hour, Takao Konishi, a Harbinger with the potential to receive the Blood of Heroes, was chosen to inherit the mantle and continue the lineage of Rai.
