First Appearance: Tales of Suspense #57 (Sept. 1964)
Created by:  Stan Lee and Don Heck

Let's be real: Clint Barton's purple and blue costume just straight up would not fly in the Marvel cinematic universe. For real though? You work for a government organization, are a highly-skilled marksman and assassin, and you're gonna dress in a Robin Hood costume designed by Prince?

Thankfully, when Hawkeye makes his grainy film debut — a cameo appearance in Thor — the costume designers seem to have borrowed his style cues from his Ultimate universe counterpart: a decidedly more professional family man with a penchant for shades and tactical, functional gear.
