Think about it, he killed a group of avengers, decided he wants Tony’s face and ripped it off or found a way to take of his skull, then put it on his disfigured face. It shows how insecure he is about his face and would be an insane plot twist that’s most won’t see coming.

Also think about the reveal after Peter sees Doom without his mask, and then after that when he realises this man just stole Tony’s face, just the rage we would see Peter show would be great.

I haven’t seen anyone mention this so what do you guys think? Or is this too much?
Dr Doom isn’t a Tony Stark variant or even just a Doom who looks like Tony, I believe he stole Tony’s face after killing a group of Avengers.
