X-Men 97 Episode 2 "Mutant Liberation Begins"

Magneto begins saving both humans and mutants, and refrains from killing anti-mutant militants. A distrustful Cyclops and Jean decide to stay with the X-Men while Rogue sympathizes with Magneto's struggles. When UN forces led by Dr. Valerie Cooper attempt to arrest Magneto for his past terrorism, he agrees to surrender and face trial to prove himself. During his trial at the UN's headquarters, the FoH stage an attack. Their leader, X-Cutioner, shoots at Magneto with a depowering radiation blast; Storm takes the hit for him and loses her abilities. Jean goes into labor and Rogue is forced to absorb an obstetrician's knowledge when he refuses to deliver a mutant's baby. Jean gives birth to a son whom she and Cyclops name Nathan. After Magneto apprehends X-Cutioner and stops the assault, he is pardoned and discussions begin for the mutant nation Genosha to join the UN. Beast tells Storm that the blast depowered her permanently, and she leaves the team to find new meaning in life. While discussing her decision, the X-Men are surprised by the sudden arrival of a woman who looks identical to Jean.
