We'll see the return of the original Captain America now revealed to have a child with Peggy Carter (Hayley Atwell, also back), following the time-displaced romance they sealed with a kiss at the end of Endgame.

How this shapes the plot remains unclear, but given the subtitle, it's unlikely the Rogers family's future will be a happy one.

"Avengers: Doomsday" hits theaters on December 18, 2026, followed by "Avengers: Secret Wars" on December 17, 2027.
