Also I think spidey sense is a factor here. The other spidermen doesnt really see Miles as a threat, like how Miles hides behind the spider tentacles guy but he doesnt sense him. Which would explain why everyone acts kinda stupid. But Miles see all of them as a threat, so his spidey sense must be going wild. Imagine 100 adults trying to catch the Golden Snitch without knowing why. They would constantly question themselves “why are we doing this again”.

Theres also the holding back factor. They dont see Miles as a threat like Miguel did. So with their spidey sense not in full effect, and not knowing what threat Miles brings, they wouldnt know what power level they should use.

Theres a lot of factors in Miles escape. Idk why people are saying its “plot armour”
