After aiding Cable against an assault on the Xavier Institute by Bastion’s Operation: Zero Tolerance forces, Caliban was taken by Ozymandias, the immortal indentured servant of Apocalypse, who revealed that the seizures were a result of Caliban’s past alteration. Growing up, a still young Caliban, who speaks in the third person, is discovered by the mutant Callisto and taken under her wing.
