Gen V is not a comic. It could potentially refer to a new generation of a product or a specific term in a particular context that's not related to comics. Maybe it's a brand name or a model number.
Gen fiction is a catch-all term for fiction that falls into distinct genres. It could be anything from horror with its creepy elements to historical fiction set in a particular time period. The genre determines the main themes and tropes of the story.
There could be Gen V comics depending on the context. Maybe in certain indie or niche comic scenes. But if you're referring to mainstream Gen V comics, it's not a common thing. You might want to check with specialized comic stores or online platforms that focus on less mainstream works.
There are likely fanfictions where Naruto has Mjolnir. Fanfiction is a realm of infinite creativity, and combining these two elements is not unheard of. It could make for a fascinating read. Naruto's character, with his strong will and growth throughout the series, could be a great fit for the idea of being worthy of Mjolnir. And the addition of the hammer's power to his ninja abilities would create a whole new set of adventures and challenges for him to face.
Well, some notable characters who can lift Mjolnir in comics include Thor himself, of course. Also, Captain America has been shown to be worthy and able to lift it on occasion.
