In Infinity War, sadly, our heroes actually die. The Avengers fail to stop Thanos from obtaining all six infinity stones, and with the snap of his finger Thanos immediatly turns half of the universe to dust. Recently introduced Avengers who are among his many casualties: Spider-Man, Black Panther, Doctor Strange, Winter Soldier, Falcon, Scarlet Witch, and most of the Guardians of the Galaxy fade turn into dust. The original five avengers –Captain America, Iron Man, Hulk, Thor and Black Widow – are left in moaned, gaping in loss and disbelief followed by credit roll.
Spider-Man Home coming and Guardians of the Galaxy have confirmed sequel after Avengers 4, and undoubtedly Marvel is planning a sequel to Black Panther, its highest-grossing solo film to date.

Now, everybody is buzzing about the upcoming Avengers 4? Marvel Studios is notorious for keeping all aspects of production under wraps, with actors being given fake scripts and trailers cut to be misleading ( I hope you haven't forgotten Tom revealing the top secret Avengers poster). We can glean some hints from the comics, though, as well as in-film references and interviews.

As for how the Avengers will know when to travel to, the Russos have hinted that Stark’s BARF technology from Civil War will play a role. The technology projects memories, which means the Avengers could comb through key events – their battle of New York, for example – to figure out their destination.
It is expected to see a closing out of several arcs as the actors of avengers contracts end. Feige says that Avengers 4 will “bring things you’ve never seen in superhero films: a finale”. That means bidding adieu to characters like Captain America and Iron Man, while setting up the future of the MCU. Sebastian Stan has claimed he’s signed on for nine films, for example, meaning he may take up the Captain America's role as in the comics. Chris Hemsworth’s contract is also ending, but he has said he’s open to a fourth Thor sequel; we also know a Black Widow film is in the works, and Mark Ruffalo has one more film left.
It is believed that Carol Danvers greets a young girl named Kamala Khan, or Tony Stark mentions a Riri Williams. Feige himself has said these characters are like James Bond; it won’t be recast but rather passed down. So while it will be painful to say goodbye to characters we’ve sat with for a decade now, their characters will never really be gone.
