Volume 1

 * Roughly 100 years following the end of the Maverick Wars, the heroic Maverick Hunters X and Zero have long since vanished.
 * A human scientist named Ciel, her Cyber-elf Passy, and other Reploid companions are being chased through an abandoned underground laboratory. Their relentless pursuers are mass-produced androids called Pantheons, among other terrible machines.
 * After taking heavy losses, Ciel, Passy and the remaining troops arrive at a sealed chamber containing Zero, who has been in stasis for a century.
 * Passy sacrifices itself to awaken Zero, who is amnesic.
 * Ciel, desperately seeking his help, explains they live in a world where Reploids are incorrectly accused of being Mavericks and systematically "retired", apparently under the direction of the once-famed Mega Man X. Shocked at this revelation and filled with doubt about his own identity as the Maverick Hunter of legend, Zero helps Ciel escape and joins her Resistance to fight against X and the utopia known as Neo Arcadia.
 * Zero conducts missions on behalf of the Resistance in order to buy Ciel time to create a new energy source that will provide everyone with a safe place to live.
 * One day, the base is attacked by Neo Arcadia, forcing everyone to flee.
 * In the midst of the chaos, Ciel confesses to Zero that she helped create Neo Arcadia as a utopia where humans and Reploids were finally able to live in peace with X as their leader, but her plans fell apart when an energy shortage crisis began and X mysteriously disappeared. To counter this, while at age six, she created a "copy" of X to be its new leader.
 * Copy X strived for X's ultimate desire for a peaceful world, but lacked the original's moral judgement.
 * Believing that the Reploid race posed a danger to humans, Copy X began an operation to brand any Reploid whom he believed to be a menace to humanity as a Maverick and annihilate them without a fair trial, in order to reduce energy consumption.
 * Zero invades Neo Arcadia and battles his way through the Four Guardians: Sage Harpuia, Hidden Phantom, Fighting Fefnir and Fairy Leviathan.
 * Phantom self-destructs in a last ditch effort to destroy Zero, but fails, while the other three manage to escape.
 * Copy X is eventually defeated, who also self-destructs in an attempt to take Zero with him.
 * Zero escapes just in time from Neo Arcadia as Copy X, and everything around him, is destroyed.
 * Running low on energy, Zero collapses in a nearby desert.
 * A faint figure appears and reveals itself as the real X, now a Cyber-elf, who has been Zero's guide the entire time. X explains that he grew tired of fighting and, without a physical body, has left Zero the responsibility of bringing peace to the world. As X vanishes, Zero finds himself surrounded by an army of Pantheons.
 * Zero accepts X's words and promises to continue the fight against Neo Arcadia.
 * The final scene shows Zero as he dashes into battle against the Pantheons and slices one in half.
