Mockingbird is a fictional superhero from Marvel comics. Also known as Agent 19, Barbara "Bobbi" Morse is an agent of the fictional SHIELD agency who is skilled in using two staves in combat and is the ex-wife of Clint Barton aka, Hawkeye.
In the Marvel tv series, Agents of Shield, Mockingbird/Bobbi Morse is played by Adrianne Palicki. Unlike in the comics, Bobbi is not Clint's ex-wife but was once married to Lance Hunter, a former British commando. Strangely, in the Disney+ show Hawkeye, Clint's wife, Laura Barton, who is portrayed by Linda Cardellini, is revealed in the season finale to be a former SHIELD agent codenamed Agent 19, Mockingbird's codename in the comics. It is currently unclear if this means that the MCU retcon Agents of Shield as non-canon with Laura being Mockingbird all along or that Laura was the previous Mockingbird before giving up her mantle and codename to Bobbi after marrying Clint.
