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