They appear in a recorded message which passed from Gabriela to The Wolverine. The workers of Essex Corp., under Dr. Zander Rice's command have captured mutant babies, and programmed some from birth, which could even occur inside the facility. However, with the help of Gabriela, most of the children have escaped. Zander Rice is later seen visiting a base which belongs to Essex Corp., and to The Reavers. After Zander's death, the company presumably shuts down, and releases it's mutants.
