Things won’t be the same in the Marvel Cinematic Universe after Avengers: Infinity War. That may include heavy losses for the good guys. In the new plot synopsis for the next major Avengers movie, Marvel Studios teases the “deadliest showdown” yet for the MCU.

On Thursday, Marvel unveiled the official plot synopsis for Avengers: Infinity War, the nineteenth film from Disney-owned Marvel Studios that will pack an inconceivable amount of cinematic superheroes for one major mission: To prevent the cosmic titan Thanos (Josh Brolin) from collecting all of the Infinity Stones, which would grant him awesome power over the entire universe.

Tellingly, the synopsis hints at death and “devastation and ruin.” Could this mean that Infinity War may actually kill off some of the franchise’s most popular superheroes? With a threat as serious as Thanos, it may happen.

The synopsis reads:

“An unprecedented cinematic journey ten years in the making and spanning the entire Marvel Cinematic Universe, Marvel Studios’ Avengers: Infinity War brings to the screen the ultimate, deadliest showdown of all time. The Avengers and their super hero allies must willing to sacrifice it all in an attempt to defeat the power of Thanos before his blitz of devastation and ruin puts an end to the universe.”

That the Marvel Universe chugs along without serious repercussions such as death has been a point of criticism against Marvel for some time. Debatably, that all of the Marvel heroes seem invincible removes the stakes of the situation, and while set pieces like the airport fight in Captain America: Civil War dazzle audiences, it’s hard to feel suspense when most of the heroes were going to walk away just fine, which they did. (Except for poor Rhodey.)

The only major MCU character to have died have been S.H.I.E.L.D. agent Phil Coulson (The Avengers) and the Warriors Three (Thor: Ragnarok). Even then, Coulson got an off-screen resurrection for TV’s Agents of S.H.IE.L.D., while the Warriors Three were so dramatically underwritten that their deaths in Thor: Ragnarok hardly registered with audiences.

Now, with Avengers: Infinity War introducing death — maybe literally, as the incarnation of Death was a major character in the original The Infinity Gauntlet comics — the MCU may actually wipe the slate clean of some of its beloved heroes. Are Captain America’s days numbered?

Principal photography on Infinity War wrapped last year. Work on the sequel, the still-untitled Avengers 4, just finished last week.

Thor’s electrifying arrival to Infinity War’s climactic battle in Wakanda might’ve just been the most thrilling moment in a movie full of thrilling moments, but it left some fans puzzled. How did Thor, Groot, and Rocket know where to go? Over the weekend, Infinity War’s directors revealed the answer, tying up a small plot hole that, to be honest, didn’t really need to be tied up.

A prevailing theory about time travel being used in Avengers 4 to defeat Thanos was just deemed a “possibility” by one Marvel director, and yes it totally involves the Quantum Realm.

In an interview published by Huffington Post with Peyton Reed, the Ant-Man and the Wasp director confirmed that the film’s post-credits scene left Scott Lang totally trapped in the Quantum Realm. He doesn’t even have an enlarging Pym Particle disc with him like in the first movie. So with the rest of Team Ant-Man turned to ash by Thanos’ snap, Scott’s only option might be to plunge right into a time vortex.

It’s not fair to blame the mustache Henry Cavill had for Mission: Impossible — Fallout for ruining Justice League, mostly because Superman’s weird CGI lip honestly didn’t even crack the top ten of that movie’s problems. But, it turns out that Fallout’s director Chris McQuarrie tried to help Justice League out.

On Tuesday, The CW announced that actress Ruby Rose (John Wick 2, The Meg), who identifies as genderfluid, is officially signed on to play Batwoman in the upcoming annual DC TV crossover. Rose will also play Batwoman should the character’s solo television series Batwoman be greenlit for production.

In this year’s crossover with Arrow, The Flash, and Supergirl, Rose will play Kate Kane, a.k.a. Batwoman, the red-headed member of the famous Bat-Family and cousin (sort of, it’s complicated) of Bruce Wayne.
