Sabretooth has escaped from captivity at the Xavier Institute after several months of confinement. He quickly realizes that the X-Men are hot on his trail as he navigates the Morlock tunnels. Sabretooth's senses detect a familiar presence nearby, and he challenges his pursuer to confront him. It turns out to be Caliban, the formidable mutant tracker of the X-Force team living at the mansion. A brutal battle ensues, with Caliban attempting to exact revenge for Sabretooth's earlier actions, including harming Psylocke and Boomer. Also, Caliban has a deep hatred for Creed as he was part of the Marauders who perpetrated the "Mutant Massacre". In a moment of miscalculation, Caliban provides an opening for the cunning Sabretooth, so Creed uses a live cable to lift himself from the water, temporarily incapacitating Caliban.
