The Six Pack is a team of fictional character in the Marvel Comics Universe. The original team debuted in X-Force #8, March (1992), created by Fabian Nicieza and Rob Liefeld.

When Stryfe travels to the present, Cable follows him with the aim of stopping Stryfe's plans as well as preventing Apocalypse's rise to power. Cable forms a group initially called the Wild Pack, but conflict with Silver Sable (who already had a group called the Wild Pack) forces him to change the name to the Six Pack. Cable travels between the present and his future with his ship Graymalkin, which contained a sentient computer program called Professor (the future version of the program built into X-Factor's Ship).

The Six Pack performs many brutal missions, often with a high body count. Later, they are hired by Mr. Tolliver, which puts them in direct conflict with Stryfe. In their last mission, Cable and the Pack confront Stryfe, who gains the upper hand. Hammer decides to surrender vital information to Stryfe, forcing Cable to shoot him in the back. Cable escapes via time-travel, unable to take his friends along. They escape themselves but Hammer ends up paralyzed and Garrison Kane loses both of his arms.

Kane is granted robotic arms by the Weapon X program. G.W. Bridge, an agent of S.H.I.E.L.D. now, acts as liaison to Weapon X. Kane undertakes a mission to destroy Cable. Hammer provides him with vital information and Kane and Cable battle until circumstances bring them together to battle Stryfe once again. Kane's arms are destroyed and Cable uses his time-travel capabilities to take him to the far future. His arms are replaced with liquid metal versions.

Six Pack has not been a contender in any CBUB matches.
