@Wilhelm_Stenvall I think 682's survival is more towards adapting what can be overcome and avoiding what can't be beaten. I remember reading that before 173 and 682 even touched each other, 682 climbed up a corner on the ceiling and watched 173 non-stop for hours. They had to shoot his eyes out only for him to grow more all over his body to keep watching. I think they eventually turned off all kinds of light and only hear things to observe and it ended up with 682 not dying.
Pretty sure the only situation where 682 is dead is that SCP with the alternate universe where all kinds of life, even the microbes, are dead.
