High resolution Avengers 4 promo art has now surfaced online, providing the best looks yet at several of the returning heroes. Marvel Studios shattered the Marvel Cinematic Universe in Avengers: Infinity War thanks to Thanos' snap wiping out half of the universe's population. The aftermath of the event left only a few heroes standing, and it will be up to them to save the day in Avengers 4.

All six of the original Avengers - Captain America, Iron Man, Thor, Hulk, Black Widow, and Hawkeye - survived to seek vengeance one more time, while Rocket Raccoon, Nebula, Captain Marvel, and Ant-Man are also set to have major roles. These 10 years were the only ones to be featured in the first bit of concept art for Avengers 4 that leaked earlier this year. Although the team shot has not yet surfaced, close-up looks at some of the individual designs (and some alternative ones) have since also made their way online. Now, some single character pieces have leaked in glorious HD to really shed some light on new character details.

MCU Cosmic discovered someone recently uploaded a bunch of Avengers 4 promo art to the MCU Wiki. Not every character received individual pieces of art at this point, but some major ones (that have major new looks) have. Captain America (Chris Evans), Iron Man (Robert Downey Jr.), Thor (Chris Hemsworth), Captain Marvel (Brie Larson), Hulk (Mark Ruffalo), and Rocket Raccoon (Bradley Cooper) each received close up HD images. Check them out below:

The most notable of the looks continue to be Hulk, Captain America, and Captain Marvel. This HD image provides a clear look at Hulk's new suit, which should only further fuel speculation that Bruce Banner and Hulk have set aside their differences (which were clear in Infinity War) to become Professor Hulk. Meanwhile, Captain America's chainmail suit and clean-shaven face points to a more traditional portrayal of the character after essentially being Nomad in Infinity War. Captain Marvel's suit matches up with the new look Brie Larson sported in some of the first images for Captain Marvel, but how she goes from the Starforce green suit to these colorful threads remains to be seen. It is also worth noting that Iron Man is still rocking his Bleeding Edge Mark L armor, so Tony may not have had too much time to tinker.

Even though these images are the only ones to emerge so far, the rest of the character designs could soon leak as well. Leaks are the only source of information on Avengers 4 right now, too, with reshoots currently going on - and Cap, Ant-Man, and Black Widow have already been spotted. With a trailer not coming until later this year, promo and set leaks may be all fans have to tide themselves over with until Marvel decides to properly launch Avengers 4's marketing campaign.
