Weapon H (Clayton Cortez) is the name of a character appearing in American comic book published by Marvel Comics.

The character, created by Greg Pak and Mike Deodato Jr., first appeared in The Totally Awesome Hulk #21 (September 2017) during the "Weapons of Mutant Destruction" storyline.

Weapon H later gained his own comic series that details what he has been up to since the end of the "Weapons of Mutant Destruction" storyline.

Clayton Cortez was an ex-military mercenary working for Eaglestar who was hired to eliminate the villagers in Ujanka for interfering with Roxxon's pipeline work. Feeling remorse for his actions, Clayton killed his own men and spared the villagers. For his betrayal, he was kidnapped and sold to Dr. Aliana Alba of the Weapon X Project's Batch-H division.

Weapon H has not been a contender in any CBUB matches.
