The return of Wanda Maximoff in the VisionQuest post-credit scene has been a bright spot in an otherwise devastating week for comic book fans. Wanda's return had been theorized for months, but it wasn't until this Tuesday that her return was officially confirmed for Avengers: Doomsday. Moreover, the post-credit scene also hinted at what Wanda's role in the movie would be.The post-credit scene of the VisionQuest finale started with Wanda's "death" in Doctor Strange in the Multiverse of Madness. We even see Mount Wundagore collapse on Wanda. The screen goes black, but this is not the end. We see a cloaked figure (Victor von Doom) clear the rubble and wake up the Scarlet Witch, informing her that her powers belong to him.While the scene doesn't confirm it, many believe that Wanda might be under Doom's control in Avengers: Doomsday.The VisionQuest post-credit scene might be a call-back to Wanda and Tony's first scene in the MCU View this post on Instagram Instagram PostWanda bewitches Tony Stark in the opening scene of Avengers: Age of Ultron, her second MCU appearance. In that scene, Tony sees his worst nightmare, the death of the Avengers in an alien invasion. While Tony is not mind-controlled in this scene, it comes close, as Wanda plants images into his mind. Now, the post-credit scene of the VisionQuest finale flips the script.The VisionQuest scene is a meta callback to Age of Ultron, as Robert Downey Jr. is back in the MCU but as Victor von Doom. Doom, while waking up, says to Wanda, “Scarlet Witch, awaken. Your power will be mine.” This means that Doom might be mind-controlling Wanda in Avengers: Doomsday. This scene might have also confirmed that she is one of the three Latverian witches.Marvel did not confirm the identity of these three witches. But the VisionQuest post-credit scene hints that one of these witches could be a mind-controlled Wanda. If that's indeed the case, Doom might be the scariest Marvel villain, as he might mind control Wanda, one of the MCU's most powerful characters.Apart from Wanda, Doom also has Hulk on his side, as one of the Avengers Endgame: Encore post-credit scenes reveals that the Latverian ruler has abducted Banner. The scene also confirmed that Mark Ruffalo will return as the Hulk in Avengers: Doomsday this December. Apart from Hulk and Scarlet Witch, fans believe that Doom's faithful lieutenant Boris might also be involved in the movie.It should be noted that Boris's role has not been confirmed by any marketing material, but leaks have suggested that he is involved in it. Moreover, they have also hinted that Boris is none other than Doctor Strange. If that's the case, Doom might be one of the biggest threats to the Marvel multiverse. However, there is more to this character.Joe Russo described Doctor Doom as a "Gothic character" View this post on Instagram Instagram PostEmpire interviewed key creatives involved in Avengers: Doomsday. In this interview, Joe Russo described what we can expect from Doom in the movie. The filmmaker described Doom as a "Gothic character" the audience is right to be afraid of:“Doom is a Gothic character. He says, ‘Hell answers to me,’ and he’s not kidding. He’s a very powerful character with some very dark magic, and he’s not above selling his soul to get what he wants. He’s worth being scared of.”Furthermore, Joe Russo also confirmed the tragedy that leaks suggested months ago:“He’s a father who’s a victim of trauma. He has lost a child. When people see the film they say it’s a very scary movie. It’s scary because he’s so profoundly damaged.”Then, co-director Anthony Russo added that Doom will be driven by ego, unlike the previous Avengers threat, Thanos. Having powerful heroes under his control might only add to his feeling of invincibility.What did you think about VisionQuest's Avengers: Age of Ultron callback?
