I am trying to ID a story (or comic book series) from the 1990s I believe. It would have been in English.

Someone is killing people who have special abilities. (Sort of like Skyler was doing in Heroes TV series)

A few hundred(?) people are born with special abilities. I am pretty sure they were all born (or conceived) on a specific day/time.

I think the date/time was the testing of the first atomic bomb. (Or maybe the Earth passed through a comet tail. Or a large meteoroid exploded over the USA.)

I believe most of these people had been known/exposed because they went public about themselves. (Either doing good deeds, or performing on shows/TV events) [I think eventually either the Government or the Specials figured the date/time cause, and identified all the unknown Specials.]

There is only 1 Special who I specifically remember, he was supposed to be invulnerable. I think he was killed while he was asleep, by evacuating the air out of the room he was sleeping in. (No Oxygen, he suffocated)

Pretty sure it turned out the one who was doing the killing, was one of the Specials. But maybe he had a pretty weak or pointless ability and was jealous of the others.

I have thoughts that maybe he tricked one of the other Specials who had high intellect, into figuring out how to kill some of the specials, before he started killing.

I am not sure if it was a story/ or a comic book series. I can recall an image of the invulnerable man being killed, but whether it was a comic book picture, or an illustration in a book, I am not sure.
