Avengers 4: 6 Dead Characters Who Will Definitely Appear

6. Howard Stark

His Death: Captain America: Civil War. Near the end of the film, a CCTV tape revealed that Howard and his wife, Maria, were killed by The Winter Soldier in December 1991.

His Avengers 4 Role: Just as the Avengers 4 reshoots were getting underway in early September, reports emerged that actor John Slattery - who played older Howard Stark in Iron Man 2, Ant-Man and Captain America: Civil War - had been on the film's set, shooting some scenes with Robert Downey Jr.

Since the movie is expected to incorporate Tony's BARF technology in some way, there's a good chance Howard will appear as some sort of vision/memory in his son's mind. Plus, with Avengers 4 possibly concluding Tony's story, an emotional goodbye with his father - which, if you think back to Civil War, is something he regrets not getting - would certainly be a fitting scene.

Around the time Slattery's involvement in Avengers 4 was reported, it was mentioned that his scenes could be left out of the film, so we'll have to see if he makes the final cut.
