Between Avengers: Infinity War and Avengers: Endgame, Thanos (Josh Brolin) emerged as the Marvel Cinematic Universe's baddest baddie — the one villain the reigned above all others. Now, just imagine the character had access to Tony Stark's Hulkbuster armor. Practically omnipotent with the full Infinity Gauntlet, plus a little extra padding courtesy of Earth's best technology. One the same day some never-before-seen Endgame concept art surfaced online, one Endgame fan has made the Thanos/Hulkbuster thought a reality, turning out an epic piece of fan art featuring Thanos in the armor first introduced in Joss Whedon's Avengers: Age of Ultron.
