One idea could be a crossover with the X - Men and the Avengers. Wolverine could team up with Iron Man and they could have a really cool dynamic, with Wolverine's rough - and - tumble style contrasting with Iron Man's high - tech approach. Another idea is a crossover with the Fantastic Four. Wolverine could visit the Baxter Building and get into some adventures with Reed Richards and the gang.
Maybe the plot could involve a new type of mutagenic weapon that is being developed in Gotham. Wolverine is sent to investigate as it could pose a threat to mutants. He meets Batman who is also on the case as it could be used by Gotham's criminals. They start off distrusting each other. Wolverine doesn't trust this masked vigilante, and Batman is wary of Wolverine's wild nature. However, as they dig deeper, they find that a common enemy from their pasts is behind it all and they must combine their skills to stop him.
First, decide which other universe or character you want to crossover with Wolverine. Then, research both the Wolverine lore and the lore of the other element. For example, if it's a crossover with Spider - Man, learn about their powers, their backstories, and their relationships. Next, come up with a basic plot. It could be a simple 'enemies - to - allies' story or something more complex like a multi - universe threat that requires their combined efforts.
Ra's al Ghul could be a great villain. He is always seeking power and immortality. In a crossover, he might see the potential in mutant genes to achieve his goals. His vast resources and knowledge would make him a formidable foe for both Wolverine and Batman. He could be plotting to use mutants in some grand scheme that would also impact Gotham, which would draw the attention of both heroes.
One idea could be that the Paw Patrol pups find Wolverine in the forest, injured. They use their skills to help him. Chase could use his police training to keep watch while Skye flies to get some special herbs that can heal Wolverine's wounds.
One possible plot could be that Wolverine somehow ends up in the Twilight universe. Maybe he's on a mission that goes wrong and he gets transported there. He then meets the vampires and werewolves in Twilight. The vampires might be intrigued by his healing factor and his adamantium claws. And the werewolves could see him as either a threat or an ally. He could get caught in the middle of the conflict between the Cullens and the Volturi, using his combat skills to tip the balance.
Storm from the X - Men would be a great addition. She has control over the weather, which could create some really interesting scenarios when combined with Wolverine's combat skills. For example, she could create a lightning storm while Wolverine battles enemies in the rain, using the flashes of lightning to his advantage.
One idea could be a Wolverine and Batman crossover. Wolverine could find himself in Gotham City and team up with Batman to take on a common enemy like Ra's al Ghul who is interested in Wolverine's healing factor. They would have to combine their skills, with Wolverine's brute strength and healing and Batman's detective skills and gadgets.
Their powers could combine in some cool ways. Naruto's chakra could enhance Wolverine's healing factor, making him even more resistant to damage. Wolverine's adamantium claws could be used in combination with Naruto's shadow clones. The clones could surround an enemy, and Wolverine could strike from different angles with his claws. Also, Naruto's ability to use different nature chakra like fire or wind could provide cover or additional offensive power while Wolverine gets in close for the kill.
The plot could involve Naruto being sent to the X - Men's universe. There, he meets Wolverine and for some reason, they have to exchange powers temporarily. Naruto then uses Wolverine's powers in the midst of a big battle against a common enemy, like Magneto who is trying to take over both the ninja world and the mutant world. Naruto's ninja skills combined with Wolverine's brute strength would make for an interesting fight.
