When an explosive event shatters the lives of the X-Men and takes away their mentor, the beaten heroes walk away from it all. But then they are given a rare glimpse into the future, and see the world in utter ruin, ruled by giant destructive robots; a world that spiralled out of control because the X-Men had given up. Wolverine, the most legendary of all X-Men, reunites the broken heroes to prevent the world's destruction.

Nitro, a young mutant, turns himself into the MRD because he cannot control his explosive powers. Toad, who is also in MRD custody, convinces the Brotherhood to bust him out and to take Nitro too. The Brotherhood use Nitro against his will to blow up the MRD bunker where all the data on every registered mutant is kept. Rogue is distressed by Nitro's pleas but cannot stop the Brotherhood's plan.

Nitro explodes, levelling the bunker, and the Brotherhood barely manage to escape. They realize Nitro is a actually a danger to them and decide to take him to Genosha. Psylocke uses her psychic abilities to keep Nitro powered down as their stolen plane zips to the island. But having been alerted from the future by Xavier that Nitro will wipe out half the world's mutants with his uncontrollable powers, Wolverine and the X-Men go after him.

They manage to intercept the plane and after using some brute force, convince the Brotherhood that they are taking Nitro back to the MRD facility where he will be safe from himself and safe for others. Wolverine does not like turning in a fellow mutant but knows it was the best thing for everyone, including Nitro. Show less
