Old Man Logan #39 Marvel Comics (2016)

LOGAN isn't healing the way he used to. Something is wrong - recent fights are leaving their marks, in ways he's never experienced before. Beaten down, Logan goes to the one people he thought he could always count on for help...The X-MEN.

But when an old pupil of Logan's asks for his help, it's Logan's enemies who will learn the hardest lesson: This old dog still has bite.
