X is built to question every order he takes, but the uniform forces him to follow them anyway. Zero doesn't have that problem, which makes watching them work the same job into two completely different tragedies. By the time you understand what Sigma is actually doing, the OVA has already answered the only question that matters: can a machine made to obey ever choose something different.
In the 21st century, artificial beings called Reploids have become an integral part of society. When some of these machines malfunction and turn violent, the Maverick Hunters exist to put them down. X, a prototype Reploid built on revolutionary designs, serves alongside Zero under General Sigma's command. Their mission is straightforward: hunt down and eliminate any rogue machine before it causes widespread destruction. But today, something changes. Sigma, the very leader guiding their operations, shows signs of corruption. As the day unfolds, X faces an impossible choice between following orders and questioning the authority he's trusted. The line between hunter and hunted blurs when the threat comes from within your own ranks. This OVA captures the origin story of one of gaming's most iconic characters, translating the tension and high-stakes action of the source material into fluid, kinetic animation. Expect fast-paced mecha combat, a protagonist grappling with doubt, and the beginning of a conflict that will reshape everything X believes about duty and loyalty.
