There are plenty of Alternate Future Wolverines to choose from. You can have your classic "Days of Future Past" Wolverine, with his greying sideburns and eventual noble sacrifice, or maybe you prefer the "Old Man Logan" Wolverine, currently traveling a ruined future America in the Spider-Mobile with Hawkeye, but for my money, you can't beat Earth X Wolverine:
Fat, lazy, drunken Wolverine may be the best Wolverine of all. As seen in 1999's Earth X #5, Wolverine and Jean got together and eventually turned into The Lockhorns. According to the text piece following the story, Jean Grey and all of the other telepaths have lost their powers, so shes stuck rolling her eyes at the 181st retelling of the time the old gasbag fought the Hulk.
Earth X was a decent series that crawled up its own arse and birthed a whole franchise of sequels that I couldn't keep up with, Universe X, followed by Paradise X with a whole bunch of spinoffs as I recall. I'm not sure if I want to know what became of the battling X-Bickersons in the increasingly convoluted saga, but if you know, please share in the comments!
Yes, I'll Still Agitating About This.
