Two-Gun Kid

Few characters straddle the frontier and the cosmos quite like the Two-Gun Kid, the sharp-shooting Western legend who rode into the Marvel Silver Age in 1962 courtesy of Stan Lee and Jack Kirby. What makes this cowboy genuinely remarkable is the company he's kept over a publishing life stretching across six decades — sharing adventures with the likes of Captain America, Thor, Iron Man, and Hawkeye, and earning a place among the Avengers and the Squadron Supreme that no ordinary gunslinger could claim. With seven key issues to his name and appearances spread across Two Gun Kid, The Avengers, and She-Hulk, he's a character whose Western roots only deepen the surprise of how far into Marvel's wider universe he's ridden. Eighty catalog appearances and still counting — this is one cowboy worth tracking down.
