Cockroach Hamilton is a Marvel Comics villain and enemy of Luke Cage who first appeared in Power Man vol 1, #28 (December, 1975.) Hamilton grew up in such poverty that he developed a sense of kinship with the cockroaches that infested his home. He is a small man who habitually wears a long coat, sunglasses, and a hat with two feathers, positioned to suggest a roach's antennae. Hamilton was an assassin working for Piranha Jones. Though he had no superpowers, Hamilton was highly skilled in the use of "Josh" a custom-made shotgun with six barrels. Though the weapon was incapable of piercing Cage's steel-like skin, it packed enough force to dislocate his shoulder.

A different version of Cockroach Hamilton appears in the Avengers: Earth's Mightiest Heroes second season episode, "To Steal an Ant Man." This Hamilton is one of the henchmen of crime boss William Cross. He uses a high-tech shotgun-like weapon that appears to fire bursts of energy.

Maya Hansen is a scientist in the Marvel Comics universe.

The character, created by Warren Ellis and Adi Granov, first appeared in Iron Man vol. 4, #1 (January 2005), and features as a major recurring character throughout the Extremis arc.
