Hawkeye is one of the Blind Bag characters in LEGO Dimensions 2: The Rise of Enoch, from the Marvel Comics franchise.
Clint Barton was trained at a circus by the Swordsman to have a perfect aim. Clint became the circus archer until he was tricked by Russian spy Black Widow into stealing Stark technology, so Hawkeye got into conflict with Tony Stark's "bodyguard" Iron Man. After some clashes with the Armored Avenger, Hawkeye got fed of being manipulated by Black Widow and reformed, joining the Avengers under Captain America's leadership, alongside Quicksilver and Scarlet Witch, at a point when the founding members had left the team. He eventually convinced Black Widow to turn on a new leaf too.
Clint and Natasha were engaged at first, but eventually they parted ways; while Natasha dated Daredevil, Clint married Barbara "Bobbi" Morse, A.K.A Mockingbird, and had her become an Avenger. Sadly, Mockingbird was killed by Mephisto.
