Weapon X is a fictional government genetic research facility project appearing in American comic books published by Marvel Comics. They were conducted by Department K, which turned willing and unwilling beings into living weapons to carry out covert missions like assassination or eliminating potential threats to the government. It was similar to human enhancement experiments in the real world, but it captured mutants and did experiments on them to enhance their abilities such as superpowers, turning them into human weapons. They also mutated baseline humans. The Weapon X Project produced Wolverine, Leech, Deadpool, Sabretooth, and Weapon H.
