Old Man Logan was written by Mark Millar, the scribe behind such scholarly works as Wanted and Kick-Ass -- and it shows. The story chronicles the adventures of a broken and beaten Wolverine in a post-apocalyptic hellscape full of violence, mayhem and oodles of incest.
The titular grump is living in shame after he failed to stop the world's villains, who finally figured out that they outnumber the good guys. Decades later, the world is in shambles, divided up amongst the remaining baddies. Logan happens to live in Hulkland, which is ruled by a squad of inbred Hulks. We are not making this up. Someone wrote this and then someone drew this.
