Behind the Web of the Madame Web movie

The casting has just been revealed for the Madame Web movie and it has most people confused about what the story is about, and this is what I think.

My idea:

I think that this will be a Terminator style movie where one of Spider-Man's Foes will try and go back in time and kill Peter Parker before he became Spider-Man. Sadly we won't be seeing Tobey Maguire Spider-Man became this is another universe's 2003.

How the characters fit:

All the heroes (Madame Web, Julia Carpenter) will try and stop the threat and Uncle ben will join their team and promise to not to interfere with Peter because it will mess up the timeline and that is why there is no Uncle ben in the MCU.

Who could the Time Traveller be?

Here are a few options:

Chronarch: A Janitor who created Time Travel-87% likely because its a small scale villain.

Maestro: A version of Hulk who travels back in time to kill everyone- 56% likely, this could happen in the She-Hulk series.

Ravonna: A being who works for the TVA- 44% likely she could prune Spider-Man after the events of No Way Home.

Kang The Conqueror: 32% he is the main villain of the Multiverse saga but I don't think its him.
