Displaced War God

Four years after piloting the legendary mech Silver Scar to repel an extraterrestrial swarm at the cost of his entire unit, veteran hero Kevin lives in quiet retirement aboard humanity's mobile fortress. When the monstrous insectoid armada reappears, Kevin volunteers to rejoin the front lines, only for rigged diagnostic tests to report zero pilot compatibility. Seizing the opportunity, a treacherous military marshal frames Kevin for high treason and orders his execution while consigning his legendary machine to the scrap heaps. Yet as the swarm breaches the perimeter defenses and executioners raise their weapons, an autonomous emergency link ignites within the abandoned machine, signaling the return of humanity's greatest warrior.
