In the DC Comics universe, Deadshot (Will Smith) is the alter ego of Floyd Lawson, a supervillain turned antihero. He’s a member of the Suicide Squad, valued as the world’s deadliest marksman, though Hawkeye might object to that.
In the Avengers, Clint Barton is Hawkeye (Jeremy Renner), a master archer and an agent of S.H.I.E.L.D. Unlike teammates Captain America and The Hulk, he has absolutely no superpowers. But on the bright side, he’s been in a relationship with Black Widow.
