Thor would be an interesting character to pair with Wolverine. Thor's god - like powers and Wolverine's tenacity would make for some epic battles. They could also have some great conversations about honor and sacrifice, coming from their very different backgrounds.
Well, Wolverine himself is obviously a very popular character. His tough - as - nails attitude, healing factor, and those iconic claws make him a fan favorite. Then there's Captain America. His leadership and moral compass often play important roles in fanfiction. And Iron Man too, with his high - tech gadgets and snarky personality.
One interesting plotline could be Wolverine having to team up with the Avengers to stop a powerful mutant - created virus that threatens to wipe out both mutants and non - mutants alike. He brings his unique combat skills and healing factor to the table, while the Avengers contribute their various superpowers and high - tech resources.
There might be a fanfiction where Wolverine has to train some of the younger Avengers. His no - nonsense style clashes with their more modern, laid - back attitudes at first, but they eventually learn from each other. For example, he could teach Spider - Man how to be more instinctive in a fight.
Definitely Captain America. Their old - fashioned values and combat prowess make for an interesting dynamic. They can lead the team together in a fanfiction, with Wolverine's wild side balanced by Cap's discipline.
One interesting fanfiction could be about Wolverine joining the Avengers on a mission to save the world from an ancient alien threat. In this story, his healing factor and berserker rage would be key assets.
