First encounters

Eleanor Murch, the woman who would become known as Nanny, is a mutant with low-level telepathy and mind control powers. She was employed as a scientist by the organization known as the Right. When Murch discovered the Right's anti-mutant agenda, she tried to thwart their plans, only to be captured and sealed in an egg-shaped armored suit of her creation. She managed to escape, driven insane by her experience.^[4]

Now calling herself Nanny, Murch vows to save mutant children, believing that their families were evil. She discovered the existence of a child called Peter, who was being held captive in Mister Sinister's "orphanage". Sinister had placed Peter in his orphanage as a small child to use him as a weapon. After realizing Peter's powers were too dangerous, Sinister decided to execute him. Nanny rescues Peter, who becomes the first of her "Lost Boys (and Girls)". Nanny fitted him with a suit of armor that would suppress his uncontrollable powers and give him the appearance of a large Man, christening him Orphan-Maker. Nanny and Orphan-Maker embarked on a crusade to "save" young mutant children by killing their parents and abducting them.^[5][6][7]

Nanny and Orphan-Maker confront the X-Men while operating out of a small, faux-town in the Australian outback. Dazzler and Havok are ambushed, captured, and transformed into children. They are given battlesuits themselves and convinced to attack the other X-Men.^[8]

Nanny and Orphan-Maker are defeated after Colossus rescues Havok from his battlesuit. Confused and disoriented from his experience, Havok blasts Nanny's ship, apparently killing Storm.^[8] Nanny and Orphan-Maker kidnap Storm and leave behind a decoy body resembling her.^[9]

During an incident where a mentally ill young mutant had taken hostages inside his school, Orphan-Maker is driven away partly because the mutant Skin manages to interfere with his suit's energy flow. He escapes in a technologically advanced vehicle disguised as an ice cream truck.^[10]

Dawn of X

In the new status quo for mutants post House of X and Powers of X, Professor X and Magneto invite all mutants to live on Krakoa and welcome even former enemies into their fold.^[11] Nanny and Orphan-Maker join the Hellions, a loose group of outcast mutants operating under Mister Sinister, alongside Havok, Kwannon, Empath, John Greycrow, and Wild Child.^[12][3][13]

Sinister sends the Hellions to steal the weapons of the Swordbearers of Arakko and thus force them to forfeit Saturnyne's X of Swords tournament. When the Hellions arrive in Amenth, Sinister reveals that they were actually sent to collect DNA samples from the mutants of Arakko. Nanny, Orphan-Maker, and Wild Child are killed by Tarn the Uncaring and his servants, the Locus Vile.^[14]

After he and Nanny are resurrected, Orphan-Maker develops a rebellious streak and attempts to be more independent from Nanny.^[15][16] This does not last long however, and he soon goes back to craving Nanny's attention. Due to Orphan-Maker's earlier behavior, Nanny neglects him and begins caring for an orphaned A.I. baby, unbeknownst to the rest of the team.^[17]

After the baby is stolen, Orphan-Maker storms the Right's base to rescue it, desperate to prove himself to Nanny. He manages to single-handedly fight his way to the heart of the compound and find the robot, only for Nanny to storm in and take it from him. In spite of his heroism, she continues to ignore him and pay attention to the robot. However, the robot's mutant-hating A.I. activates, causing it to kill Nanny. Distraught over her death, Orphan-Maker embarks on a rampage, killing everyone he comes across.^[18][16]

Following his rampage, Orphan-Maker is put on trial by the Quiet Council of Krakoa and sentenced to exile in Krakoa's Pit of Exile, with Nanny choosing to accompany him.^[19] After spending some time in the Pit, they are freed by Cypher along with Third-Eye, Nekra, Oya, Madison Jeffries, Melter, and Toad. The group is tasked with hunting down Sabretooth.^[20]

The group is attacked by a super-powered Orchis member called the Creation, who kidnaps Orphan-Maker for experimentation. Nanny assured the rest of the team that, if Orphan-Maker is separated from his armor, no one on Earth will survive.^[21] At Orchis's base, Orphan-Maker is taken care of by Dr. Barrington, who manipulates him into removing his mask. Without his mask, Peter's powers activate, killing Barrington and threatening to destroy the Orchis base.^[7] Peter is rescued and given a new suit, built for him by Nanny and Jeffries.^[22]
