Have you read the comics? If not - Peter Parker is constantly traumatized by shit going horribly wrong or failing to account for something frequently. I’d say it’s a running gag but Stan Lee wanted a super hero people could connect with at a human level.
It will almost certainly be a multi verse Tony Stark gone evil.
Or a Doombot with Stark’s face to fuck with the Avengers.
And I’ll bet anything it’s Spider-Man that unmasks him and discovers it, leading to a whole mental breakdown by Peter.
Hasn’t Peter had enough breakdowns yet?
