SPOILERS FOR ACROSS THE SPIDERVERSE:
My consipracy theory/prediction for beyond the spider verse is that Miguel O'Hara's backstory is full of shit and he deliberately broke canon in a different universe by killing the Miguel that was there and taking his place (not that he randomly died, bc what a lousy lie). Also, I believe the Miguel that Spiderman 2099 killed was the spiderman in that reality, causing the world to collapse after his death.
Reasons:
1. Miguel says that he found another universe where the Miguel in that reality was going to die, went to the moment of his death, and then took his place... huh???? How did he find a universe where he was able to predict that Miguel was going to die if it wasn't a canon event? Alternatively, if the Miguel in that world was already dead then he wouldn't have been able to switch places with him because people don't usually respond well when people they believed to be dead come back to life. Also, hypothetically if he was able to predict that the alt Miguel was going to die and when, it's still kind of f-ed up to watch him die (not help), take and dipose of his body, and then steal the dead man's family. It's almost worse than murder.
2. In the scene where Miguel is carrying his daughter away from the collapse, Peter B Parker and other citizens are there, but guess who isn't? That world's spider man!! Conviently nowhere to be seen during a world ending catastrophe (because Miguel killed him earlier).
3. It explains why Miguel is so personally upset with Miles's existence- Miles is someone who wasn't supposed to be spiderman and killed (kinda) and successfully took the place of the old spiderman which is exactly what Miguel wanted to do and failed.
Other things I've noticed:
1. Kingpin from the first movie and Miguel O'Hara have the same plot. They both lost their family and will stop at nothing to get them back through interdimensional travel. Goes really well with the theme of repetition in ASTV.
2. The vials that Miguel injects himself with look slightly different from each other, maybe they're filled with spider venom from different dimensions? It would explain how he has his super speed in the first scene with Gwen but not in the chase scene with Miles (where an adult man in slippers carrying a baby is moving faster than him) because it's not a feature of his suit but a temporary power from a spider bite. Is this a stretch? Yes, but it ties into my theory that Miguel created the collection of Spidermen to find one with an ability capable of bringing back his family so I'm sticking to it. (Also we know he's a bitey vampire so I think his bite gives him the powers of whoever he bites)
Just putting it here so I can either feel super smart or super dumb when the next movie comes out đź’–đź’–
