91. Wolverine vs. the Hulk (HULK # 181 vol. 1)
When Wolverine came flying out of nowhere at the end of Incredible Hulk #180, while readers probably did not realize they were seeing the introduction of one of the most popular characters of all-time, they did likely realize that this Wolverine character was a lot different than most heroes.
In Incredible Hulk #181, we discover that Wolverine has been sent by the Canadian government to deal with the Hulk AND the creature known as the Wendigo. After first attacking the Hulk, Wolverine then determines to trick the Hulk into helping him stop the Wendigo. Once that is done (where Wolverine stabs Wendigo in the neck!), he turns on the Hulk.
Wolverine’s brusque manner of acting and the rather lethal powers he had (what hero had CLAWS back then?) really stood out, as did the fact that here was this tiny guy with not exactly thrilling powers, and he was totally hanging with the Incredible freakin’ Hulk!!!
The first fight ends in a draw, as Wolverine manages to knock the Hulk out, but not before the Hulk does the same to him.
After they both wake up, the fight begins anew. This time, Hulk delivers a deadly blow - only Wolverine’s great skill allows him to roll with the punch and rather than being killed, is only knocked unconscious.
The Hulk is the winner!
