10 Times The Avengers Ruined Peter Parker’s Life
3. Not Being Able To Recognise His Worst Enemy (In Spider-Man's Body) - Superior Spider-Man #7
When Otto Octavius took over Peter Parker's body and killed him off, many fans expected that the Avengers would immediately recognise that their beloved youngest member has been replaced by a man who acts and behaves entirely different - which made it feel pretty awful when they did some basic tests and then decided that Spider-Man was still definitely Peter.
And though this is almost excusable, it has to be remembered that at this point the Avengers are supposed to be quite close to Peter - or, at the very least, aware that he wouldn't just suddenly become a totally different person in every way.
Similarly, in a profession where being mind-controlled or outright replaced is exceedingly common, it seems super awful that, after checking Spider-Man isn't a skrull, they decide he must be totally fine, even though he just murdered someone in cold blood like five minutes ago.
Thus, due to a lack of genuine care - and due to the team's two geniuses being MIA - Otto Octavius goes spidey-ing around without a care in the world.
