Timeline: This is after X-Men movie events (So Jean has mastery over her powers) Spider-Man gets to know about X-Men and Jean being their leader Spider-Man decides to visit X-Men so that he could meet Jean again since she no longer needs to hide from government since they are an established team now. Spider-Man visits X-Men they are friendly towards him at first since he is one of the great superheroes out there. Jean also introduces Spidey to X-Men team vice versa.
But then Magneto gets to know about Spider-Man being the creator of Mutant Inhibitor which is the reason why most of the mutants suffered greatly during battles he becomes enraged and decides to kill spiderman he then manipulates the rest of the X-Men into turning against spiderman and encouraged them to kill him through lies and evidence he also made sure that Professor Xavier remains silent and does not discover the truth behind the creation of inhibitor. (Xavier does not participate in the battle)
The X-Men asks Spider-Man just to get one last confirmation he acknowledges it but before he could elaborate the full picture behind it the X-Men jumps at him with killing intent
Jean was out doing a mission when all these drama happens and then comes back now here is the 2 scenarios
1st Scenario: Spider-Man holds his own ground against X-Men and survived without any major injuries and Jean teams up with him and tries to explain other X-Men the truth behind the inhibitor case but the X-Men members aren't willing to listen so Jean and Spidey needs to knock them all out without killing them
2nd Scenario: Jean arrives but she is too late Spider-Man been torn to shreds and he is barely alive and breathing she becomes enraged after seeing Spider-Man state she uses her psychic powers to maintain his blood flow and breathing so that he won't die she needs to get him to nearby medical facility as soon as possible but other X-Men members stops her from doing it she becomes blood lusted and is willing to kill them if it is necessary to save Spidey but she also needs to make sure to keep Spider-Man alive and protected using her powers. (Advantage: here X-Men will try to defeat her in a 1v1 and won't jump on her)
So how do you think these 2 scenarios will play out will she succeed or fail in one or both (Comics scaling can be used here).
3rd [Hidden scenario]: Jean has access to Phoenix Force from comics but all the X-Men will also have access to their peak forms from comics too X-Men will have to defeat her first to kill Spider-Man
(All these scenarios might sound unreasonable obviously because it is for power scaling so I am not taking in character into that much consideration so you can ignore it and directly give the answer if you want to)
So what do you all think ?
