Marvel’s Avengers: Endgame: Encore adds four scenes linking the film to Avengers: Doomsday: Doctor Doom confronts Bruce Banner, Loki joins Steve and Peggy, the TVA sees worlds collapse, and Doom forges a mask in a scene echoing Tony Stark’s Iron Man suit.
In the Banner scene, he records a video while working on a gamma-radiation project before Doom appears off-camera and says he has come to collect him. Loki appears in the branch timeline where Steve returned to Peggy and offers to help them. A TVA sequence shows worlds colliding and being destroyed.
The end-credits scene echoes the sound of Tony Stark building his Iron Man suit before revealing Doom forging a mask. The article interprets this as a possible Stark-Doom connection because Robert Downey Jr. plays both characters, but says the link is not explained. It is also unclear whether these scenes will appear in Doomsday.
