Superhero comics: What insane story/character developments do avid followers take for granted but would blow the minds of anyone only peripherally aware of them?

wait, cap killed truman?

and how is Truman neutral?

immediate nitpicks: X-23 has surely killed WAY more than than that, even counting on-panel only. you'd think her own mother would be a "notable kill"

good thing they didn't include Bishop who straight up committed multiple genocides into the billions during his crazy time-traveling spree to kill Hope Summers

lol at Iron Man's having killed 5 heroes and 1 villain

I guess they're only counting deaths that weren't reversed by the end of the story arc? Otherwise Thanos should be on the top of the list.

Though they do list The Torch killing Mr. Immortal, even though the guy's literal superpower is that he always comes back to life after getting killed.

man things got really murder-y from the 90s on, I don't recognize the names of at least 2/3rds of the characters involved on that chart

Stpuid superhero deaths
