People have been swooning over Chris Evans' new Captain America bearded look. This poster will be giving a lot of feels.
Tony Stark's new armor will bring the Bleeding Edge / Model Prime designs for the comics to life onscreen, as fans have long hoped for. Here's hoping the armor - and RDJ's Tony Stark - survive the experience.
Mark Ruffalo's Hulk is currently on a three-movie story arc that began in Thor: Ragnarok and continues into Avengers: Infinity War. We can't wait to see where this particular road leads!
Chadwick Boseman's T'Challa / Black Panther is the current king of the box office - and looks just as regal here in this Avengers: Infinity War poster!
Tom Holland looks great in his new Iron Spider suit - and we can't wait to see the big tech upgrades the suit reveals.
Scarlett Johansson will be a changing the game with her new silver-hair and tactical gear look. Move over Linda Hamilton...
Sebastian Stan's Bucky is no longer The Winter Soldier, thanks to help from Shuri, and this poster is a lot better at depicting his new bionic arm than a recent one-sheet did.
Benedict Cumberbatch's Doc Strange looks all mysterious, mystical, and badass here - but when Ebony Maw breaks him, it will just be a lot of screaming and sweating.
Doctor Strange's right-hand man is about to see his job as a mystic protector get a lot more complicated - starting with the moment Hulk comes crashing into the Sanctum Sanctorum.
Thankfully Chris Hemsworth's Thor has his eye-patch and scar in the proper places on this poster. In the film, the Thunder God will set out to forge a new mystical weapon replacement for his hammer, with some new comrades in tow...
...That's right, Guardians of the Galaxy's lovable rascal duo (voices Bradley Cooper and Vin Diesel) will be aiding Thor on his quest or a new weapon. Because if there's anything that Rocket loves, it's weapons.
Chris Pratt's Star-Lord / Peter Quill will be leading the remaining Guardians on another crucial mission: getting to the Infinity Stone left with The Collector before Thanos does. Needless to say, it doesn't go very well.
The fight will be personal for Zoe Saldana's Gamora in Infinity War, as she finally tries to get justice for her people by taking down Thanos, once and for all.
Karen Gillan's Nebula is the other angry "daughter of Thanos" looking for payback - but as the original Infinity Gauntlet storyline reveals, Nebula may have her own agenda...
The other wounded heart that's been looking for Thanos all this time is Drax. It'll be interesting to see how Drax, Gamora and Nebula all balance their respective thirsts for vengeance - or if they end up tripping each other up.
Elizabeth Olsen's Scarlet Witch will find herself in a very emotionally vulnerable position, trying to balance her growing affection for The Vision against the terror of what will happen to him if his Mind Stone is ripped out by the Black Order.
The Avengers will need serious upgrades to stand against Thanos - and for once, Tony Stark won't be there to provide the answer. The tech strategy will then be left to Letitia Wright's Shuri, as the MCU heroes prepare for a final battle in Wakanda.
Paul Bettany's Vision will just be trying to survive by staying one step ahead of Thanos most formidable and ruthless lieutenants, Corvus Glaive and Proxima Midnight.
Danai Gurira's Okoye will simply be trying to do what she always has: protect Wakanda. But with her nation's borders now open, that defense has become harder than ever to maintain.
Anthony Mackie’s Falcon will be a trusted sidekick as always, helping Captain America and Co. to make a final stand against Thanos in Wakanda.
This is our best look yet at Don Cheadle's new War Machine armor! After his injury in Captain America: Civil War, it's good to see Tony's BFF back on his feet.
