The Chosen One is inmortal (by pure luck)
The Chosen One is inmortal by luck even right now in his No One form.
I'm not saying he is a lucky person (cause he has been trough hell and worse-), but when it comes to literally dying, his luck saves his ass for some reason.
For example: You could stab TCO (the chosen one) in the leg or any other non-vital place and you would succeed, but if you try to stab him in the heart, throat or any vital place, something has to happen that makes it soo that you can't stab him there, even if you precisely calculate every chance, exactly know where you're gonna stab him, anything could happen: you get something in your eye right before stabbing and miss, the blade of the knife is too little and it can't go through, the knife turns out to be a plastic one (even if before it worked perfectly), something happens before that gives him the opportunity to escape, etc
His luck let's him being thrown around, tortured, getting his ass beated, enslaved, etc. But it draws the line when it comes to dying, even after turning into No One and falling into the literal ocean and (probably) not khowing how to swim, he will make it out alive by luck or something
