The MCU's Marvel Cinematic Universe.
No character is more anticipated than Wolverine. Part of the Logan, is widely regarded as the best of Fox's X-Men films and one of the best superhero movies to date. All this means that, when it comes to Wolverine, Marvel Studios is under real pressure to do something different.
The best approach would be to introduce Wolverine not as a hero, but as a villain. It's so easy to forget that, when Wolverine made his debut in 1984's The Incredible Hulk #181, he was actually an antagonist. Wolverine worked for Canada's Department H, and he was dispatched to confront the Hulk. Years later, Mike Carey's "Original Sin" event revealed this was actually all a trick; Department H knew Charles Xavier was scouring the globe looking for mutants, and they wanted to ensure Wolverine wound up on his radar. They had concluded Xavier was too powerful, and they had Wolverine the X-Men in order to assassinate him. Shockingly, "Original Sin" revealed he made an attempt, but underestimated Xavier and was defeated. Xavier manipulated Wolverine's mind, erasing most of his memories, transforming him into an X-Man against his will.
Wolverine may be considered a superhero, but Marvel has a history of turning him into a villain. One of the most striking examples was in Mark Millar's "Enemy of the State," a story in which Wolverine's powers were inhibited and he was killed. He was then resurrected using the Hand's sorcery, which turned him into one of their puppets. Under the Hand's control, Wolverine became their top assassin, assigned to kill other superheroes so they too could be resurrected, and ultimately sent on a mission to kill the president of the United States. This was part of the backdrop for the famous "Civil War" event, in which the US Government lost confidence in its superheroes and imposed a Super Human Registration Act; Wolverine's going rogue demonstrated the risks of the previous status quo.
Marvel Studios are sure to introduce Wolverine sooner or later, but they would be wise to use him as a villain first. They could draw loose inspiration from "Enemy of the State," making him a top assassin who is sent against high-profile targets. That would naturally allow Marvel to demonstrate his capabilities, reminding viewers just how dangerous he really is. What's more, this would potentially allow Marvel to explain why the world turns on mutants, creating an environment where they are hated and feared. Imagine if one of the first mutants in the MCU was a ruthless killer who rampaged across the MCU. Finally, when the time is right, they could then bring him into with their version of the X-Men and turn him into a hero once again. It would be an arc never seen before on the big screen, making their Wolverine utterly unique.
