The X-cutioner is a fictional anti-mutant activist and supervillain from Marvel Comics, and an enemy of the X-Men.
Carl Denti was "just another field agent in the sea of operations working for the FBI." Then, after a fellow agent's death, Denti "inherited" a case file loaded with information on many mutants of the United States as well as pointing to the agent's stockpile of pilfered weapons and technology from past cases.
Believing it necessary to take extreme measures against these mutant perpetrators, Denti fashioned the X-cutioner identity using the collected technologies and information—hunting down, and if necessary, killing mutant criminals.
