Clint Barton
A one-time criminal, S.H.I.E.L.D. operative, the world's greatest sharp-shooter and founding Avenger.
Where is he from?
Hawkeye debuted in Marvel's Tales of Suspense #57 in 1964 as an Iron Man villain. He was among the former villains who joined the team in Avengers #16 in 1965. Since then he's been a team mainstay, leaving only to found the West Coast Avengers or to die for a couple years (comics are weird). Clint is played by Jeremy Renner in the Marvel Cinematic Universe, and is slated to pass on the role of Hawkeye to his comic sucessor Kate Bishop in a Disney+ streaming series in 2021, which is probably going to be based on Matt Fraction's fan-favorite 2012 to 2015 Hawkeye series.
