The Watchtower
Released from his servitude to Apocalypse, Caliban once more reverts to his childlike state although he retains the monstrous physique he attained through Apocalypse's machinations. Subsequently, Caliban is captured by an anti-mutant medical research facility called the Watchtower. The Watchtower wishes to use Caliban for their own purposes but he is freed by X-Force. Caliban has devolved into a feral mental state where he only grunts and snarls but he manages to help X-Force against a menace called the Skornn.
