Also know, does Logan get his healing powers back in the Wolverine?
Yes, he retains his healing factor. He removed the parasite from his body and his healing factor returns in the movie. His skeleton was never screwed with. His adamantium claws were sliced off, but his healing factor generates new bone claws instead.
Also, how does Wolverine lose his healing factor? Wolverine (Hugh Jackman) was losing his mutant healing power in Logan because, ironically, he was poisoned for decades by the Adamantium coating his bones and claws, which ultimately lead to his tragic death.
Likewise, why is Logan sick in Logan?
It's not until much later in the film that we learn why, exactly, Logan is so sick: the Adamantium in his body is poisoning him. For those of you who don't know, Adamantium is metal put into Wolverine's body during Project X — it's what makes his claws so darn effective.
Why is Logan so sick in the movie?
In Logan, adamantium is apparently poisonous
Wolverine's death at the end of Logan might be attributed to a combination of the poisoning that was eventually going to do him in and all those slashes and bullets in the final scene.
