If there's one thing we know about Avengers: Infinity War, it's that it will feature a gigantic cast. Seriously, it's gonna be huge. Most of the characters who will appear have already been seen in some form or fashion, but believe it or not, there will be at least one new character that will debut at least one new character amidst the familiar faces. Here's what co-director Joe Russo recently said on the subject:
Russo dropped this subtle revelation in a recent interview with The Indian Express, and while common sense dictated that new players would be added to the third Avengers flick, it begs the question of which Marvel characters are big enough to shine among the established heroes and villains. We have a few candidates in mind...
To clarify, just because Carol Danvers might show up in Avengers: Infinity War doesn't mean that she'll have her Captain Marvel powers yet. Brie Larson was officially revealed to be playing Carol last month at San Diego Comic-Con, but as we pointed out, the announcement came much earlier than Marvel's past hero castings have come. One of the reasons for that could be that she'll appear in another movie before her own solo adventure, and directors Joe and Anthony Russo may have accidentally let slip a few months back that Avengers: Infinity War will be that movie. However, Captain Marvel writer Nicole Perlman recently said that she's altering Carol's origin story so it doesn't resemble Green Lantern's. So while we will eventually see Carol flying around and shooting energy blasts as Captain Marvel, she may just be a normal Air Force officer in her first MCU movie.
Adam Warlock played an integral role in the Infinity Gauntlet storyline, so it's hard to imagine him not participating in Avengers: Infinity War. Guardians of the Galaxy featured a cocoon in The Collector's gallery that looked a lot like the one Adam comes from in the comics and even though James Gunn later said this wasn't his cocoon, whose to say there isn't another one just like it? Adam has a long history with Thanos in the comics, and he was the one responsible for organizing Earth's heroes against the Mad Titan when he collected the Infinity Gems. He can easily fill this same role on the big screen. It's also worth pointing out that Adam has a dark side of his own (known as the Magus), and since Infinity War is no longer being advertised as a two-part story, perhaps he'll be set up as the villain for Avengers 4, which arrives just a year later.
Avengers: Age of Ultron introduced Helen Cho to the MCU, a scientist who built the synthetic body that would later become The Vision. Longtime Marvel comics fans immediately noticed she shared the same last name as Amadeus Cho, a boy super genius who nowadays is serving as the new Hulk in the comics. Amadeus' mother is also named Helen in the comics, so the MCU could easily introduce her son during Infinity War. Helen was last seen helping set up the New Avengers installation, so she could still be working there when the third Avengers flick kicks off. Amadeus' impressive intellect is enough to catch the attention of Earth's Mightiest Heroes, and going a step further, maybe he could help come up with a plan to defeat Thanos. Amadeus is also the kind of character who could become a prominent player in Phase Four.
Carol Danvers is the current Captain Marvel, but long ago, that title belonged to Mar-Vell, a Kree who originally came to Earth to spy on humanity, but eventually became one of its protectors. Even though Mar-Vell was dead by the time the Infinity Gauntlet storyline was printed, he had battled Thanos on numerous occasions. Since the Kree have already been seen in Guardians of the Galaxy and a few Agents of S.H.I.E.L.D. episodes, it's easy enough to bring Mar-Vell into the festivities, whether he looks like a normal Kree or has been altered to look more human. Assuming he doesn't die battling the Mad Titan, that could lead to an appearance in Captain Marvel, as her powers in the comics originated from him. Even with her origin being changed, it would be great to see him involved in her life and shown off more as a superhero.
Beta Ray Bill
Remember, Thor isn't the only one who can lift the hammer Mjolnir. It can be wielded by anyone deemed "worthy," and that includes the alien Beta Ray Bill. We don't know yet how Thor: Ragnarok will impact the MCU, but its possible that it's destructive events will lead the eponymous protagonist to lose his powers by the end, i.e. his control over Mjolnir will be severed. That opens the door for Beta Ray Bill to discover the mighty weapon in Avengers: Infinity War and wield it himself. When Thanos attacks Earth, the hammer could guide Bill to Earth so he can help the Earth heroes. Imagine their shock when they see their ally's weapon is being held by a horse-looking being. Obviously Thor will eventually regain Mjolnir, leaving Bill to wield Stormbreaker, but with the Thor series seemingly coming to an end, time is running out for Bill to get his due in live action...well, CGI, but you get my point.
What do moviegoers know about Thanos so far? He's an alien powerhouse who loves floating lounge chairs and wants to gather all six Infinity Stones? Okay, but why is he so desperate to do the latter? Well, if he's like is comic book counterpart, it's because he wants to prove his love for the personification of Death, usually depicted as a woman. Death is one of the many abstract entities from the Marvel universe, so it will be difficult to present "her" to audiences not familiar with the comics. Nevertheless, the fans need to understand that Thanos' motivation doesn't stem merely from wanting to be a typical conqueror. He needs to demonstrate how passionate he is for the force that eliminates life. Where better to learn that than in Avengers: Infinity War, the movie where Thanos will finally get off his ass and start showing why he's feared throughout the universe?
