I don't, that isn't my thing. I believe these guys are simply too much in the end. The mind gem for one, I believe is an easy win. Even if not, I believe Kurse, Hulk and Thor are enough to put him down. 2 beasts and 1 with exotic powers are always going to beat one beast. I understand Doomsday is a beast and seems to evolve past various forms of punishment. However, as I've seen you argue is Shaw threads, that doesn't mean we take that to a no limits fallacy. It's like saying if TOAA punches DD he wouldn't die... he would. He isn't beyond all physical injury as that has never been shown or proven. He seemed to be beyond what was thrown at him, but that isn't an all encompassing thing no matter the degree of physical punishment. Don't believe that, nor was it shown. Thus, I believe they can put him down via some means. The mind gem being a seemingly easy way to do it.
