The main characters in Shark Tail Crossover Fanfiction are often a blend of different entities. There could be a shark - tailed humanoid who is the protagonist. They might be on a quest in their own world when suddenly, due to some crossover event, they are transported to a different fictional realm. In this new place, they interact with the native characters of that realm, like elves or dwarves. And together, they form the main cast as they face various challenges and adventures that come with this strange crossover situation.
Shark Tail Crossover Fanfiction is often about combining the concept of shark tails with elements from different fictional universes. For example, it could be a crossover where characters from a popular fantasy series encounter beings with shark tails. It might explore new storylines, character relationships, and unique settings that result from this strange combination.
The main characters could also be Sasuke from Naruto and Gray from Fairy Tail. Sasuke's cool and brooding nature combined with his Sharingan abilities would be a draw. Gray's ice - make magic and his habit of accidentally stripping could add some humor. In the harem, characters like Ino from Naruto and Levy from Fairy Tail could be part of it. Ino's mind - control jutsu and Levy's intelligence with books and runes would bring different elements to the story.
Goku from Dragon Ball Z could be a great crossover character for Natsu. They are both very strong and have a love for fighting. Goku's ki - based attacks and Natsu's fire magic would make for some epic battles. They could also train together and learn from each other's fighting styles. Also, Alucard from Hellsing could be an interesting crossover. His vampiric powers against Natsu's magic would create a very dark and intense story.
In the 'Shark in the Dark Story', the most obvious main character would be the shark. But depending on the nature of the story, there could be other important characters too. If it's a story about the shark's journey, perhaps there could be a seagull that the shark sees flying above the water's surface during the day before it goes into the dark depths at night. Or there could be an old, wise octopus that the shark encounters in a dark cave, and they have some sort of interaction. Maybe there are also other sharks that the main shark has a relationship with, like a rival or a mate.
Since we don't know the exact story, it could be the friendly shark itself as the main character. There might also be other sea animals like fish, dolphins, or turtles that interact with the shark and are important characters in the story.
Since I don't know the story well, I can't say for sure. But the shark must be one of the main characters.
It's hard to say for sure, but perhaps the main characters are a couple of siblings. The older sibling might be protective of the younger one when it comes to the idea of sharks. And there could be a new kid in town who joins them in their exploration of the shark world. They all together form the main characters who drive the plot of the 'Shark Kids Story'.
One unique feature is the combination of two very different concepts. Fairy Tail is a world full of magic, wizards, and guilds, while sharks are sea creatures. Fanfictions often blend these in creative ways, like having shark - inspired magic.
Eren from Attack on Titan is often a popular choice in crossovers. His strong will and ability to transform into a Titan make him a really interesting character to pair with the Fairy Tail mages. He could be seen as a bit of an outsider in the Fairy Tail world at first, but then gradually learn to work with them.
Annabeth Chase is also a common crossover character. Her intelligence and strategic thinking can play well in the Fairy Tail world. She could potentially befriend characters like Lucy, who also rely on their wits at times. They might exchange knowledge about different mythologies and magic, creating an interesting dynamic between the two.
