Clint Barton became Ronin not long after Echo gave up the identity, choosing to take on the Ronin guise to reflect his trauma and disillusionment as an Avenger.
In the film Avengers: Endgame, Clint Barton (portrayed by Jeremy Renner) becomes Ronin to take vengeance on criminals who survived the Blip, such as the Tracksuit Mafia, before he is recruited by Natasha Romanoff to join the Avengers in undoing the Blip.
Hawkeye and Clint Barton's Ronin
While the movie does not outright refer to Clint as “Ronin,” he dons the character's attire in the film. Hawkeye confirms that Clint was, in fact, Ronin for an unspecified amount of time in the gap between the Snap and Endgame.
Ronan the Accuser is a villain-turned-anti-hero from Marvel Comics and the on and off antagonist of the Guardians of the Galaxy team as well as an enemy of various superheroes in the Marvel universe, including the Fantastic Four, Inhumans, Avengers, and Captain Marvel.
Ronin, a masked vigilante who tracks down and slaughters criminals, is the alias Hawkeye uses in Avengers: Endgame after he loses his family in Thanos' universe-altering snap. The film never actually outright refers to Barton as “Ronin”, but he wears the character's outfit and mask in the movie.
The Ultimate version of Ronan the Accuser is the son of Thanos, and is a part of his empire. He is ultimately defeated by the Thing.
Clint abandons his Hawkeye mantle to become Ronin after Thanos' snap in Avengers: Infinity War dusted his entire family. In Avengers: Endgame, Natasha Romanoff finds Clint in Tokyo, taking down Japanese gangsters under the Ronin mantle.
Ronin in the Marvel Comics
In the Marvel Comics, Hawkeye was not the first character to take on the mantle of Ronin. That honor goes to Maya Lopez (aka Echo), who first assumed the Ronin identity in 2005's “New Avengers #11.” In a twist of fate, Echo appears in “Hawkeye” and is getting her own spinoff Disney+ series.
Among Clint Barton's many heartbreaking actions after losing his family to the Blip was a tenure as masked vigilante Ronin. As Ronin, Clint hunted down criminals and murdered them in the streets, dealing out a cold sense of justice that matched his new cold-hearted demeanor.
Despite Clint Barton's dark past as Ronin he'd like to leave in the past, a new Ronin is potentially being teased for the MCU in Marvel's Hawkeye. Marvel's Hawkeye could be setting up a brand new Ronin for Phase 4 despite Clint Barton's dark past in the role as seen in Avengers: Endgame.

While Ronan lacked the durability of a half-Celestial, he held the Power Stone and lived in Guardians of the Galaxy thanks to his superhuman Kree physiology, Accuser armor, and brief time holding the stone.
After a long search, Ronan acquired the Orb, but after realizing it had housed the Power Stone, he instead betrayed Thanos and chose to take the Orb's power for himself. Using his new-found power, he and his forces attacked Xandar, only to be defeated and killed by the Guardians of the Galaxy.
Throughout the first three episodes, however, we learn that Laura not only knows about the Ronin suit but that she's also familiar with the Tracksuit Mafia.
While spelled slightly different, the character's origins are quite different as well, as Ronan is an alien fanatic of the Kree Empire, whereas Ronin is an Earth-based cover identity.
Ronan was the son of Thanos, the ruler of the Acheron Empire.
Ronan easily overpowered Drax, throwing him into a pool of spinal fluid.
Drax comes from the Kylosian people, a race of primitives who are considered naïve and hopelessly underdeveloped by the more advanced galactic groups. As a result, Drax is extremely unaware of basic concepts such as metaphors and customs.
That's why Thanos looks like a giant purple guy; Thanos' Deviant gene deformed his appearance. On the other hand, Eros looks like a regular human, just like other Eternals, because they belong to the same evolutionary path.
The Ten Rings, after all, are circular in design, like much of the technology utilized by the Eternals. They also appear to be energy-based in their use, much like the tools and weapons used by the Eternals are fueled by cosmic energy.
An Eternal–Deviant warlord from the moon Titan, Thanos is regarded as one of the most powerful beings in the Marvel Universe. He has clashed with many heroes including the Avengers, the Guardians of the Galaxy, the Fantastic Four, the Eternals, and the X-Men.

Hawkeye went on a murderous rampage during the Blip under an alter-ego, Ronin. It is revealed in "Avengers Endgame," that during the five years after Thanos killed half of all life, Hawkeye (Jeremy Renner) took on a new mantle, Ronin, and went on a rampage on the criminal underworld.
