Why does Doctor Doom need Scarlet Witch in ‘Avengers: Doomsday’? Here are 5 theories that could explain Wanda’s return to the MCU

Scarlet Witch's potential return in "Avengers: Doomsday" has fans speculating about her role, especially given Doctor Doom's interest in her powers. Here are five theories explaining why Doom might need the Scarlet Witch:

1. Wanda's forgotten past and her role in the "Children's Crusade": One theory suggests that "Avengers: Doomsday" could adapt Marvel's "The Children's Crusade" storyline. In the comic, Wanda disappears after "Avengers Disassembled" and "House of M," living with Doctor Doom in Latveria with her sons. Doom manipulates her powers, and the young heroes help her escape, revealing that she was innocent.

This theory could work if Doom controls her memories or manipulates her to use her powers for his benefit. However, there's no confirmation if Marvel will adapt this storyline.

2. Wanda as part of the Latverian Witches: Wanda might be connected to the mysterious Latverian Witches, who have appeared in promotional material for "Avengers: Doomsday." Some posters, convention displays, and leaked concept art show one masked figure as red, leading fans to speculate about her involvement. There are also conflicting reports about the number of witches, with some mentioning three or four characters. If Wanda is indeed part of the Latverian Witches, it could explain her connection to Doctor Doom.

3. Wanda replacing Molecule Man in "Secret Wars": Another theory speculates that Scarlet Witch could replace Molecule Man in Marvel's "Secret Wars" storyline. In the comics, Doom creates Battleworld using immense power and chaos magic. Wanda's reality-altering abilities might make her a suitable replacement for Molecule Man. She's already shown the capacity to create entire towns in "WandaVision" and travel between universes in "Doctor Strange in the Multiverse of Madness."

Doom might use Wanda's powers to build Battleworld, control the multiverse, or offer her a deal for her return, leading to a potential conflict with her family later on.

4. Wanda destroying Earth-10005 to save her family: Following "VisionQuest," fans theorize that Doctor Doom could use Wanda to destroy Earth-10005, the universe home to the original "X-Men" movies. The post-credits scene in "Avengers: Endgame" shows Doctor Doom collecting Bruce Banner, who is then seen with Wanda in an underground bunker.

Doom might promise Wanda a new reality, including being with her family, in exchange for her help in destroying Earth-10005. This would create a heartbreaking situation when her family discovers what she's been forced to do.
