One idea could be a crossover where Naruto characters end up in Smallville. For example, Naruto could use his ninja skills to help Clark Kent deal with some of the strange threats in Smallville that his superpowers alone can't handle easily. Another idea might be a story where the Kryptonite in Smallville has an unexpected effect on Naruto's chakra, leading to new and unique powers for him. Or perhaps a fanfiction where the characters from Smallville learn about the ninja world and decide to train like ninjas to gain new skills.
A cool Naruto Smallville fanfiction could involve a time - travel scenario. Imagine Naruto traveling back in time to Smallville's past and influencing events that shape Clark's future as Superman. Maybe Naruto helps young Clark understand and control his powers better, or he teams up with Lex Luthor before he turns bad. It could also be interesting to write about how the ninjutsu from Naruto's world could be used to combat the advanced technology or alien threats in Smallville.
One idea could be that Naruto is somehow transported to Smallville. He could use his ninja skills to help Clark Kent deal with some of the more dangerous villains in Smallville. For example, when Clark is having trouble with a kryptonite - enhanced foe, Naruto's speed and combat skills could come in handy.
A cool fanfiction concept could be a situation where the magic in Game of Thrones has an impact on Smallville. Suppose a powerful sorcerer from Westeros accidentally opens a portal to Smallville. This could lead to all kinds of chaos as the residents of Smallville have to deal with magic they've never seen before. On the flip side, the Kryptonians' powers could be seen as a threat in the eyes of the Game of Thrones characters, leading to a potential conflict. Or perhaps some of the noble houses in Westeros could try to form alliances with the powerful beings in Smallville for their own political gain.
One idea could be that the Winchesters end up in Smallville while hunting a demon that has some connection to LuthorCorp's experiments. Maybe the demon is using the kryptonite there for its evil deeds. Another could be that Clark Kent discovers the existence of the supernatural world through Sam and Dean. He could initially be skeptical but then realize there are threats that even his powers might not be enough to handle.
Well, a cool plot could be that an ancient, powerful entity from the Supernatural world is awakened in Smallville. Clark discovers it while trying to protect the town. He realizes he can't handle it alone and contacts Bobby Singer through some means. Bobby then sends Sam and Dean to help. They initially have a hard time trusting Clark because of his superpowers, but soon realize they need his help. As they battle the entity, they discover it has ties to an old, forgotten lore that involves both the kryptonite on Earth and a powerful demon they once fought. They have to combine their knowledge and powers to defeat it.
One idea could be that Chloe discovers a hidden power in Smallville that is linked to her own family's past. Maybe she stumbles upon an old diary in the Kent barn that reveals secrets about a long - forgotten relative who had a connection to an otherworldly force in Smallville. This could lead to her and Clark teaming up to uncover more about this mystery and protect Smallville from a new threat that is drawn to this newly - discovered power.
One idea could be that the characters gain special abilities or powers based on the game mechanics. For example, Clark Kent might discover that he can fly only when he completes certain in - game quests. Another plot could involve the characters being trapped in the game world and having to find a way out. They would have to face challenges and enemies within the game that are based on the 'Smallville' universe.
One idea could be that a vampire from The Vampire Diaries somehow ends up in Smallville. Maybe they're drawn there by the strange meteor - related powers in Smallville. Another could be a character from Smallville, like Clark, having to deal with the vampire lore and politics of The Vampire Diaries' world. It could create really cool scenarios where Clark's powers are put to the test in a different way, like against a vampire's super speed or mind control abilities.
One idea could be that the alien technology from Roswell somehow finds its way to Smallville. The kryptonite in Smallville could have an unexpected reaction with the alien biology from Roswell. Maybe the characters from Roswell come to Smallville in search of a new energy source and end up getting involved with the local mysteries and the Kents.
One idea could be that Clark is kidnapped by an unknown group who are trying to study his powers. They keep him in a high - tech facility and try various experiments. Another could be that a villain from his past kidnaps Clark to get revenge for past defeats and holds him hostage in an abandoned building. A third idea might be that Clark is kidnapped by someone who believes he can use Clark's powers to save their dying loved one.
One idea could be that Batman visits Smallville to investigate some strange technology that has been showing up in Gotham and has ties to LuthorCorp. He teams up with Clark Kent, who is still in his early days of understanding his powers. They could have a cool dynamic where Batman is initially suspicious of Clark but then realizes he's a powerful ally.
