In the comic world, adamantium doesn't poison Wolverine. It's bonded to his skeleton and gives him enhanced strength and durability rather than causing any harm or poisoning.
The story would change in many ways. For one, his relationships might be affected. Some of his friends might be a bit wary of his new, dangerous weapon. Also, his training would focus more on physical combat skills. He might seek out new teachers or training methods to master the use of the claws. And his enemies would likely target the claws, trying to find a way to disable them, which would add new plot twists to the story.
Sure does. There are specific arcs where Wolverine's adamantium is removed for various plot reasons. This often leads to significant changes in his character's abilities and story development.
Well, it could be really cool. Naruto with adamantium claws would add a whole new dimension to his fighting style. He could use the claws in close - range combat, maybe even combine them with his Rasengan. Picture him slashing through enemies and then following up with a powerful jutsu. It would also change his appearance, making him look more menacing.
Wolverine does get his adamantium back in specific comic storylines. This often occurs after intense battles and adventures that lead to his restoration of this key attribute.
Maybe Harry is cursed by a dark wizard and as a result, he grows adamantium claws. He then embarks on a journey to find a way to reverse the curse. Along the way, he meets new characters who are either afraid of him because of his strange new feature or are intrigued and want to help. His friends, like Hermione and Ron, are initially shocked but then support him in his quest to get rid of the claws or learn to control them.
Yes, there might be. The world of fanfiction is vast and full of creative crossovers. Fans often like to combine different fictional universes to create unique and interesting stories. So it's very likely that someone has written a fanfiction where Harry Potter has Wolverine claws.
