[*]Karen Page's AIDS (Daredevil, 1998)- Weren't they planning a version of this story for the TV series? Junkie sex worker dies from her lifestyle is not super controversial. It actually the story a lot of conservatives would promote.
[*]Gwen Stacy's death (Amazing Spider-Man #121, 1973)- They literally did this just a few years ago in the Garfield Spidey movies...
[*]Ultimate Captain America's portrayal (Ultimates)- Well, Ult Cap is an A-hole, so yeah...
[*]The Stamford Incident, which involved a school being destroyed (Civil War)- eh, I can totally see this happening in a MCU TV series or movie...
[*]Princess Diana of Wales joins X-Statix (X-Statix, 2003, edited before publication to remove references to the real life princess, who died in 1997),,,only cuz it's a real person and yeah it didn't happen then...
[*]Norman Osborn impregnating Gwen Stacy (Sins Past)....
[*]Shang Chi, son of Fun Manchu (Master of Kung Fu)..only cuz Marvel doesn't have the rights to that specific character. They've since worked around it.
[*]Falcon revealed to be Snap Wilson, former gangster (Captain America #186)...A lot of fans don't like it cuz it goes back to blaxploitation stereotypes, but...it could be made to work in modern times.
[*]Marcus rapes Ms. Marvel (Avengers #200)...this one, yeah...
[*]Spider-Man reacts to 9/11 (Amazing Spider-Man vol 2 #36)...???
