Miles led the exhausted group through Obadiah’s underground base while explaining how Obadiah gained his Apocalypse-like powers and why he was harvesting Mutant genes. They headed for the imprisoned Clarice Fong, whose Spatial Teleportation ability could help them escape, as Obadiah prepared to inject himself with a collection of Mutant genes.

• Miles sealed an alloy door behind the group and used his powers to make the Barrage Chimera explode against it.
• Miles told Rebecca and the others that Obadiah’s Spatial Teleportation ability came from a Mutant girl imprisoned in the containment sector.

• Obadiah defeated Madeleine and returned to the bridge, where his overwhelming psychic power stopped Miles’s controlled Chimeras and threatened the remaining defenders.
• Charles told Miles that they had found Erik, and Miles used their telepathic link to give Clarice the sensations of Montana so she could open a portal there.
• Professor X, Charles Xavier, and Magneto, Erik Lehnsherr, emerged from Clarice’s enormous portal.

Magneto joined the battle against Obadiah and the Chimera Legion, but his reckless attack endangered civilians and reignited his conflict with Charles. Miles uncovered an ATHENA agent and a hidden scheme, while Obadiah seized Magneto after learning how weakened he was; Clarice rescued him just as Logan charged at Obadiah.

• Magneto tore apart the Roosevelt Island Bridge to stop the Chimera Legion, but Richter and Mona prevented the trapped civilians' cars from falling into the river.

Obadiah and the Mutants fought on the bridge until ATHENA's Super Leech suppressed their powers and fighter jets dropped bombs on them. Obadiah destroyed the Super Leech with the Phoenix Force, Magneto redirected the bombs, and Miles disabled them; Obadiah then opened a portal and withdrew with his forces.

• Magneto and Obadiah battled while Charles and the X-Men led the Mutants and Chimeras into a full-scale assault.

Miles searched for a way to save Madeleine and traced a hidden web linking her creator, Dr. Stasis, Obadiah, and the ATHENA Office. He left the Institute with a team to find Dr. Stasis, while Charles and Magneto confronted the threat of Project ATHENA and its worldwide Leech Towers.

• Miles learned that Madeleine had less than two days to live and suspected that Dr. Stasis might be the only person who could save her.
• Miles recognized connections among Madeleine, Dr. Stasis, Obadiah, Ritts Yoel, and Dr. Nathaniel, and sensed that a hidden figure might be manipulating them all.

Miles and his team infiltrated the Aegis Bioscience Research Center to recover data connected to Dr. Stasis, escaping after Charlotte’s possession and Aurora’s hacking exposed them. The data narrowed the search to one location: the Alameda Secret Research Center in California.

• Obadiah Apocalypse inserted Miles Zero’s genetic sample into the Gene Conduction Device in his underground laboratory.
• Miles’s team reached the Aegis Bioscience Research Center, where Charlotte used Astral Roaming to possess a soldier and infiltrate the facility.

• Miles brought Madeleine to meet Dr. Stasis, but she began losing control until Stasis injected her with a sedative and revealed his identity.
• Stasis explained that Madeleine was created as a weapon against Obadiah and offered Miles Phoenix Serum as a dangerous way to help her share the Phoenix Force’s burden.
• Stasis revealed that he, Obadiah, Ritts, and Nathaniel were four clones of Dr. Nathaniel Essex, and that their rivalries had driven the Apocalypse Plan, Project ATHENA, and Madeleine’s creation.
• Miles deduced that Ritts had triggered Madeleine’s earlier loss of control and feared that Nathaniel might be at the Xavier Institute, but Aurora did not answer his call to Charles.
• A powerful psychic presence seized electronic systems across the country, and Miles recognized it as Obadiah’s before a portal opened in the lab.
• Obadiah Apocalypse emerged and pierced Dr. Stasis’s chest with Cyclops’s energy beams, killing him as Miles tried to escape with Madeleine.

Miles and his allies rescued Madeleine from a Phoenix-fueled rampage, and Miles awakened a new power after entering her mind and sharing her black flames. He then continued investigating the hidden forces behind Project ATHENA and identified Christopher Lopez at Johnson Base, where Magneto had once been imprisoned.

• A nationwide electronic storm caused by Obadiah fused with Miles's electronic-signal ability shut down the academy's systems, and Charles traced the disturbance to him.
• Obadiah killed Dr. Stasis and confronted Miles at the Alameda Research Center, but he retreated when Madeleine awakened in a berserk Phoenix state.
• Miles injected the Phoenix Serum and, with Prosta's help, reached Madeleine through her mental world as Laura and Dani tried to hold back her storm.
• Miles found Madeleine engulfed by black flames, refused to leave her, and shared the flames until both lost consciousness; they later awoke together aboard the Blackbird.
• Miles warned Charles about the hidden conspirator, disclosed what he had learned about Four-in-One Essex, and decided to continue investigating despite Obadiah's return.
• Aurora identified the mysterious man from Jennifer's memories as Christopher Lopez, a supervisor at Johnson Base, the place where Magneto had previously been imprisoned.

Miles linked Magneto’s escort route to the Vorgan Building, a genetic research office, and Nathaniel Essex’s Egyptian hospital, then tried to contact Charles as a frightening theory emerged. Meanwhile, Magneto brought Obadiah to Cerebro to find the Leech Factories and destroy Project ATHENA, leaving Charles injured outside the sealed Mind Control Room.

• Obadiah used Cerebro to locate Mutants worldwide and unleashed a global electronic storm, but Miles stabilized the Blackbird against its effects.
• Miles led the group to Vorgan Building, where he sensed a powerful, anguished consciousness and struggled to communicate with it.
• As the group descended toward the basement, Dani’s powers turned the consciousness’s nightmare into visions of Erik’s losses and his murder by Mr. "♦".
• The visions ended in the basement, where Miles found a dried corpse wearing a suppression collar and used the X Terminal to reconstruct its face.
• The scan identified the corpse as Erik Lehnsherr, leaving Miles shaken by the discovery.

Miles and his companions uncovered the truth about the magnetic-field wraith, while Obadiah and Magneto destroyed the Leech Factories before Magneto’s identity as Nathaniel Essex, Mr. Sinister, was exposed. Charles attacked Mr. Sinister in grief over Erik’s murder, but stopped to spare the Institute’s students, allowing Mr. Sinister to escape as Charles collapsed.

• Miles identified the basement ghost as Erik’s spirit fused with the building’s magnetic field and decided to return later with Charles to retrieve his remains.
• Aurora told Miles that Obadiah had gone to the institute, and Miles saw a missile strike the mountains as Obadiah launched weapons worldwide at all 137 Leech Factories.

• Charles connected with Erik’s fragmented consciousness and relived their shared memories as he began restoring his old friend.
• Charlotte possessed an engineer, planted explosives in the military camp’s ammunition depot, and sacrificed her consciousness to delay Mr. Sinister; the depot exploded, but she did not return to her body.
