[Marvel] How would opinions change on Deadpool, if they realized that he was right about the fourth wall?
gpt
Honestly, people's opinions of Deadpool would be the least significant topic if it was determined that the entire Marvel universe is a work of fiction. Once a character discovers this "truth", their entire world view gets turned on it's head. Any concept of free will is an illusion (as their every word is written by an author). Every tragedy that befell them now has definite person(s) responsible. Imagine Scott Summers realizing that Jean Grey was killed and resurrected with the Phoenix Force because she was "boring" and comic sales needed to be higher. Or Peter Parker coming to the conclusion that Gwen Stacy died not because of his failures, or the Green Goblin's malice, but because the editors didn't want their young hero to get married.

And then of course, Deadpool tells them about "retconning" and giant flash of light from Doctor Doom's new time travel experiment envelopes the Earth and it's suddenly 2 hours earlier.
