The cyborg known as Nanny was originally a scientist and inventor who made major advances in the development of cyborg technology. She was empoloyed by an organization known as The Right, but was unaware of the purposes to which the Right used her work for.

Eventually, however, she learned that the Right was utilizing her technology to destroy mutants. Being a mutant herself, she was furious, and tried to halt this use of her work.The Right, however, captured her and imprisoned her within an egg-shaped cyborg battlesuit that she had herself designed. They hoped to force her to work for them permanently. Apparently her sanity was somewhat damaged by the shock of what had happened to her.

Nanny finally escaped from the Right, which then attempted to destroy her but failed.

Nanny then dedicated herself to saving young mutants from exploitation. However, the methods by which she goes about this are morally questionable.

Nanny first rescued a young mutant named Peter from captivity by Mr. Sinister. Sinister had come to regard Peter as uncontrollable and intended to kill him.

Peter was the first of Nanny's "Lost Boys," the first of many mutant children she "rescued." Peter also became her assistant in his armored guise as the Orphan-Maker.

Together, Nanny and the Orphan-Maker sought out mutant "children" and rescue them so that they will never be harmed. Sometimes Nanny would rescue them from truly evil people, other times from their harmless parents, who the Orphan-Maker would then kill, making them orphans.
