Ever since the ending of The Avengers, moviegoers have been waiting to see what the smirking purple alien in a floating chair would become. For comic fans, this threat is known as Thanos and even after teasing him in 2012, Thanos has made little impact from his own doing in the Marvel Cinematic Universe. He's had a small role in Guardians of the Galaxy and again appeared in the post-credits scene to Avengers: Age of Ultron, but damage has not been done by his hands, yet.

Avengers: Infinity War will finally see Josh Brolin's Thanos fully realized as he finally wields the Infinity Gauntlet and collects all six Infinity Stones. Kevin Feige recently told us that he could be viewed as the main character of these films, and with Marvel releasing a video announcing the official start of production, they have also unveiled new looks at the Mad Titan himself.

Included in the featurette released by Marvel was two new looks at Thanos. In one he is about to fit what looks to be either the Space or Power Stone into his golden glove, while the other gives us a look at him without his prototypical armor, and his monstrous muscles may be even more intimidating.

Given the set up that Marvel Studios has done on Thanos to this point, they certainly have lofty expectations to fill. Fans have been waiting years now to see Thanos finally take on the heroes of the MCU, so Marvel will truly have to deliver their greatest villain yet to try and meet them. That said, the concept art alone makes an impression thanks to Thanos' imposing figure - with or without his armor.

Ultimately, what this shows is that The Mad Titan is not likely to go into battle in a vest without his gauntlet, when he takes on the various heroes of the MCU in Infinity War. Meanwhile, the artwork of Thanos in his preferred seated position here could be a look at him gathering resources before he makes his move - or, if not that, him sitting victoriously after his first encounter with the Avengers and/or Guardians.

All that is left at this point is to see how Thanos looks in action. The MCU has so far been successful at showing him with a minimal amount of movement, but once he begins to take on (and likely kill) characters in combat, he will have to not only have the power to do so but also have the right visual style to make it seem believable. With production only just beginning on Infinity War, any action shots of Thanos in action are likely months away - but already, highly-anticipated.
