Updated December 15, 2017: An expanded checklist of where Marvel's "Where Is Wolverine?" comic book post-credits scenes will appear has been released by the publisher. The company has commissioned their "most acclaimed artists" to draw teaser panels (done to mimick cinematic post-credits scenes) to be included in several titles in January through March. All issues including this will be cover-marked with the slug at right.
Along with the originally announced January titles (Captain America #697, Amazing Spider-Man #794, and Mighty Thor #703), the promotion has grown to include: February's Marvel 2-In-One #3, Black Panther #170, and Avengers #680; and then March's Incredible Hulk #714, X-Men: Red #2, and Invincible Iron Man #598.
Of course, in current Marvel Comics continuity there currently four Wolverines active: the "All-New" Wolverine (Laura/X-23), Old Man Logan, the "Ultimate" Wolverine (Jimmy Hudson), and the original Wolverine. (That's not to mention the Wolverine/Hulk hybrid Weapon H, who is launching a solo series in 2018).
The original Wolverine, Logan, returned after a three-year death in August 2017's Marvel Legacy #1 and is featured in promotions for the upcoming Infinity Countdown title.
Original Story: Marvel has revealed the next whereabouts of the original Wolverine, who returned in Marvel Legacy #1 - and they’re borrowing a trick from Marvel studios for it.
Wolverine will appear in a series of “after credit” scenes in some Marvel titles that, when read in sequence, will touch on Wolverine’s status quo – a la Marvel Studios’ ubiquitous “stinger” scenes.
“Fans have been speculating about Wolverine’s whereabouts since he first reappeared in Marvel Legacy #1—and the Marvel Universe is left just as unaware!” said Marvel SVP and Executive Editor Tom Brevoort in a statement. “So keep your eyes peeled as Canada’s favorite citizen makes his presence felt in titles all across the Marvel line! It’s all leading to something—but what?”
"Mystery has always been part of Wolverine's DNA,” added senior editor Mark Paniccia. “He's one of Marvel's most interesting and popular characters. Fans are going to have a helluva ride finding out where he's been and how he came back.”
The “stingers” will appear in the following titles, starting in January, with more unnamed titles to follow:
CAPTAIN AMERICA #697
MIGHTY THOR #703
AMAZING SPIDER-MAN #794
