Mesmero of Earth-5700s origins are identical to those of Mesmero
's of Earth-616, except when Mesmero was sent to Neverland Agent Brent Jackson stopped the shuttle carrying Mesmero and helped him regain his powers. He then joined Jacksons forces until Malcolm Colcord
destroyed Jacksons' faction and reinstated Mesmero in the ranks of Weapon X. Malcolm then ordered Wildchild, Sauron, and Mesmero to infiltrate the Xavier Mansion. There Mesmero hypnotized Professor X and forced the X-Men to surrender. Then Wolverine showed up and Malcolm had the X-Men killed. Afterwards the Sentinels
that accompanied them killed Wildchild and himself.
