Merge:Two-Gun Kid

The Two-Gun Kid is a cowboy gunslinger in the Wild West of the Marvel Comics universe. The original Two-Gun Kid, Clay Harder, appeared in Two-Gun Kid #1 (1948). The second Two-Gun Kid, Matt Liebowicz (alias "Matt Hawk"), first appeared in Two-Gun Kid #60 (1962). The latter Kid is better known today, thanks primarily to his connection with and later full integration into the Marvel Universe.

Two-Gun Kid #60 retconned the Clay Harder character out of existence. Matt Liebowicz was a lawyer from Boston, Massachusetts who was inspired to fight evil by the stories of the fictional "Two-Gun Kid", Clay Harder. After being trained in combat by the gunfighter Ben Dancer, Liebowicz assumed the dual identities of "Matt Hawk" and the Two-Gun Kid. With his horse Cyclone, his partner "Boom Boom" Brown, and a pair of pistols, he became one of the West's most prolific heroes, often teaming up with the Rawhide Kid, Kid Colt or the Phantom Rider. In one of his first adventures he fought an alien, and in other early outings he fought criminals who could only be called supervillains. During one adventure, he was brought to the present day via time travel and joined the superhero team of The Avengers. He fought alongside them before leaving to wander America alongside his teammate Hawkeye, and eventually returned to his own time, occasionally making a cameo appearance in other Western tales or stories of time travel.

The Two-Gun Kid: Sunset Riders limited series revealed that the Kid had married, only for his wife to die in childbirth; this series also revealed that the Kid had brought a cache of modern weapons back with him from the future. The later limited series Blaze of Glory depicted the Kid as retired from gunplay, now going by the name of Clay Harder and working as a full-time lawyer. The Rawhide Kid convinced him to return to action, but the Two-Gun Kid died in battle against the racist mercernary Nightriders, alongside his old partners Kid Colt and the Outlaw Kid.
