The mutant children of criminals met by Nanny in prison, the Lost Children became her personal army in her quest to 'rescue' other 'abused' mutant children.
16 years old. Son of one of Nanny's fellow inmates, Jack has enhanced speed that is not as fast as Quicksilver’s, but would (gladly) give Indy 500 drivers a run for their money. He can also create cyclones like Quicksilver. He’s a normal boy who has run into some scrapes in his life and has been in and out of foster homes for many years since his mother was sent to prison for killing his father. He hasn’t really been compelled, as he sees Francine as the mother he never had, like Peter does. He and Peter have some disagreements to that effect, as both compete to be Nanny’s “favorite.” Will need therapy for Stockholm Syndrome once it’s all over. He’s a show off, mouthy. He’s fairly strong, as strong as a teenage boy can be. Not super strong, but he’s no weakling. He has street smarts and some street fighting skills.
14 years old. Daughter of a fellow inmate of Francine’s serving time for armed robbery. Lucy can enlarge inanimate objects to control them in order to fight and protect herself. She is innocent but is quick to defend Nanny (not by her own choosing) and gets easily angered and frustrated. Due to mental regression by Nanny, has a preference for stuffed animals and action figures and uses them to defend her. She enjoys the circus and has named her favorite teddy bear Bonzo. Tomboy. Was very, very resistant to Nanny at first but was mentally regressed to the mind of a 10 year old and that took care of that problem, for the most part. The regression was botched, however, and wasn’t as perfect as Nanny had planned. Lucy’s 10 year old mentality is affected when she is overcome with emotion (ie pissed), reverting back to a little closer to her 14 year old self. Wound up undergoing intensive psychic therapy to help reverse Nanny’s effects.
13 years old. Daughter of an inmate in for burglary and assault. Addie is able to monitor life signs and detect mutant abilities on almost a continental scale. She is quiet and shy, not much of a fighter. She doesn’t need much compelling as she doesn’t want to get on Nanny’s bad side because she saw what was done to Lucy. She just plays bloodhound for Nanny. She finds Molly, Alice, and Gene.
Speedfreak, Big Top, and Monitor are a group of mutant children who were kidnapped by a woman named Francine MacArthur-Jacobs, also known as Nanny and forced to help her kidnap other children who she thinks need saving. After a run in with the X-Men, the children were all returned home.
