We first see Hawkeye as Ronin in Avengers: Endgame. Basically, after his entire family is obliterated during the blip, Clint takes the opportunity to let out his anger in a semi-productive way. He takes on the Ronin identity, suit and all, and becomes a masked vigilante as opposed to a well-known hero. In slaughtering criminals, Hawkeye also makes a lot of enemies.

There are moments in Endgame when Hawkeye tries to emotionally process his actions as Ronin. Once his family comes back and Natasha dies while working to reverse the snap, Clint has even more to process.

Luckily for us, Hawkeye reveals a bit more about Clint’s stint as Ronin, including that he angered the Tracksuit Mafia. We also learn that “Ronin” means “masterless samurai” in Japanese, so it was truly Clint’s attempt at answering to no one.

In Avengers: Endgame, we see Clint slicing criminals in Tokyo when Natasha Romanoff tracks down her old pal. Although Clint seems to be somewhat satisfied with his new life, Natasha persuades him to leave Ronin behind and don his Hawkeye persona once again to reverse the snap.

It’s since been confirmed that, although we don’t know exactly how long Hawkeye was Ronin, it could have been any amount of time within the five years of the blip.
