Update: We have a theory as to why Hawkeye becomes Ronin in Avengers 4.
More set photos from Untitled Avengers confirm Hawkeye's transformation into Ronin by offering up a sample of his costume. Jeremy Renner has been an important piece in the Marvel Cinematic Universe since Phase 1, but he's yet to receive the same level of screen time as his fellow Avengers members. Iron Man, Captain America, and Thor have received trilogies, while Black Widow and Hulk received co-star status in Captain America: The Winter Soldier and Thor: Ragnarok, respectively. Hawkeye on the other hand has been been waiting to step into the spotlight.
The closest he's come was in Avengers: Age of Ultron when Joss Whedon brought Clint Barton's secret family into the mix, which many interpreted as a sign Hawkeye's time was coming to a close. The red herring worked and he's since become a mentor to Scarlet Witch, but his role in the next two Avengers films looks promising according to some rumors - and those rumors appear to be true.
Chinese website Weibo has revealed a slew of photos from Avengers 4 of Renner on set, but not in action. Renner is wearing a long trench coat to hide what is underneath, but his legs are a dead giveaway of what is next for Hawkeye. The black suit with gold lining can only mean Barton has ditched his Hawkeye persona in favor of a different identity: Ronin. See a few of the photos below, but click the link to see the entire batch.

It is unfortunate that this tease does not offer up the complete look at the Ronin costume, but the tease should be satisfying enough considering it is finally confirmation of Barton's story moving forward. Rumors of this arc for Hawkeye first arose a few months back with reports pointing to tragic events of Avengers: Infinity War putting Barton on this path. The earlier speculation points to a potentially deadly story for the Barton family, with the loss of his family sure to set the marksman on a darker journey.
This is the latest example of how Avengers 4 could reshape things for the beloved heroes. We know Black Widow will still be sporting her new blonde look in the film, but what the fourth film holds for many of the other characters is unknown. What this does establish is the threat of Thanos and the very real consequences of his arrival - assuming this is not all part of an alternate reality. There is still plenty to uncover with Untitled Avengers, much of which will hopefully remain a mystery until after Infinity War hits theaters.
