In 150,081 CMT, Protoman was one of the Knights of the Keruvim who fought in the Battle of Neo Z'traa. When Herd Stir alerted him to the fact that a nearby Vrai village was under attack by an army of Pokémon, Protoman replied that they would "cross that bridge" when they got to it, proceeding to help Herd Stir cut down several of the Great Beings' troops with his longsword. Protoman then slashed into several more soldiers with his blade and leaped into the air to impale another from above as the Knights rallied against their enemies. As Uterio's forces began to dwindle, Protoman cheered to his comrades that victory was near, and it was achieved moments later.
Later, Protoman and Herd Stir returned to fight on the behalf of the Knights of the Keruvim in the Battle of Corrantia. Protoman leaped onto a giant insect controlled by Nadle and rode it towards a building in the fortress's courtyard, deflecting attacks from enemy forces in the process. Though he began to be overwhelmed by the sheer number of attacks, Protoman easily dispatched the enemy squad that was attacking him with his longsword/arm-blade. However, just when it seemed that he would leave the skirmish victorious, Protoman was shot in the head and killed by an enemy sniper. His corpse rolled off the insect and fell onto the battlefield below.
