Weapon X is a secret government program in the Marvel Comics universe, primarily known for creating enhanced super-soldiers. It is most famously associated with the character Wolverine, who underwent painful experiments that bonded the indestructible metal adamantium to his skeleton, granting him enhanced abilities and regenerative healing. The program has produced various other characters, including Deadpool and X-23, each with unique enhancements and abilities. Weapon X often explores themes of ethics in scientific experimentation and the consequences of tampering with human biology, highlighting the struggles of those who have been subjected to its experiments.
