Who she is: Laura Barton
Her power: No superpowers, unless you count the miraculous power of giving birth, you monster.
Her story: Laura Barton’s sole appearance thus far has been in Avengers: Age Of Ultron. It’s revealed that Clint Barton (a.k.a. Hawkeye) has a wife and two children (with a third on the way), unbeknownst to the other Avengers, save for Black Widow, who is Barton’s longtime friend. When the Avengers need a place to hide for several days while they figure out how to fight Ultron, Hawkeye takes them to his remote home, where Laura greets them and sets them up for a stay. She supports her husband’s work, but is probably relieved when he decides to retire, as shown in Captain America: Civil War. Though she’s probably not so relieved when Hawkeye goes racing off to help Captain America and gets himself imprisoned by the U.S. government.
Played by: Linda Cardellini
Currently, Laura Barton is: Probably worried sick about her vanished husband—unless he’s already back home after being rescued by Cap at the end of Civil War.
Where will we see her next? Unknown (and possibly never), though Avengers: Infinity War is the likeliest possibility.
