In one last ditch effort to save her “father,” X-23 takes the Adamantium bullet that Logan had been saving for himself, and uses it to take down X-24.
As a result of his prolonged Adamantium poisoning, Logan finds himself wholly outmatched and is subsequently impaled on a sharp tree branch by X-24.
Eventually, he comes across the evil Wolverine clone, X-24, and the two versions of Logan begin to hack and slash each other apart in the middle of the forest.
She tearfully kneels by Wolverine’s side as it becomes apparent that his fading healing factor is not going to save him from this one, and he dies while telling her not to be the weapon that Transigen created.
