Nanny and Orphan-Maker

Origins

Eleanor Murch is a mutant with low-level psychic powers who worked as a scientist by 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 armor of her creation. She managed to escape, driven insane by her experience. Now calling herself Nanny, Murch vowed to save mutant children, believing that their families were evil. Her first ward was Peter, a mutant with uncontrollable and destructive powers, who she rescued from being executed by Mister Sinister and gave armor to suppress his powers. In the course of their actions, Nanny and Orphan-Maker first clash with the original X-Factor team, then the X-Men.

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. 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.

After he and Nanny are killed in battle and subsequently resurrected, Orphan-Maker develops a rebellious streak and attempts to be more independent from Nanny. 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.

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. As a result, Orphan-Maker is sentenced to exile in Krakoa's Pit of Exile, with Nanny choosing to accompany him. After spending some time in the Pit, the two are freed by Cypher along with the other prisoners and tasked with hunting down Sabretooth.

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. 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. Peter is rescued and given a new suit, built for him by Nanny and Jeffries.
