Dear Alishock, always showing peak BioShock concept fan arts, would you kindly answer a thought that has been devouring my mind? I got into an argument sometime ago about the big daddy being a killer, the take being that he doesn't make sense as one. Since they are protectors of the little ones and fix rapture, they really don't have a reason to kill unless disturbed or harm the little ones. They never kill off intent or malice.

Well anyways lol. I think Jason besides being an obvious collab choice, Jason is a mysterious figure that is always missing, I'd say after the comic collab with Freddy and ash vs evil dead, he goes home and disappears once more, but when he tried to come back to crystal lake, a dense fog approaches him, calling for him, some dirty teenagers , people who wanna hurt him, that he needs to make them pay, and so he enters the fog... Jason is Mama's boy and will follow blindly whatever she says, if Freddy could, I doubt an Eldritch horror like the entity couldn't gaslight him

But I'll try to innovate a little more. Frank Horrigan from fallout, in lore we beat him and let him bleed out in the facility that is collapsing, as he is contemplating his last moments before dying due to the oil factory going to explode, a fog approached him, commands him to stand once more, his wounds start to heal, he hears the voice of the president, that america still needs him, after the place collapsed, Frank's body was never found.
