The X-Treme Sanctions Executive is a fictional paramilitary police force appearing in American comic books published by Marvel Comics, in particular those featuring the X-Men, and related spinoffs. The organization is charged with keeping the peace between mutants and humans in the Marvel Comics universe. The team was first mentioned in X-Treme X-Men #40, when Storm presents her team with an offer to join a new, government-backed squad, and debuts in Uncanny X-Men #445 (August 2004).
