‘Avengers 4’ promotional art shows updated costumes, Captain Marvel, and Thanos

Marvel Studios has done a pretty good job keeping things under wraps for Avengers 4. Fans know very little in terms of what to expect from the film, but a few revelations are inevitable. New promotional art has emerged online showing updated costumes for some of Earth’s Mightiest Heroes, an added teammate, and the latest look at Thanos.

There really isn’t very much in the images that could be considered a spoiler, but they inspire some speculative thoughts that could lead us into that territory. With that in mind, I’ll throw out a spoiler warning before revealing the images.
