A crossover with the Avatar: The Last Airbender world would be cool too. Gajeel could be a metalbender from a far - off land. He could interact with Aang and the gang, and his skills could be both a help and a hindrance in their quest to save the world. For example, his metalbending might be useful in building structures but could also cause trouble if misused.
Luffy from One Piece could also work well. Luffy's carefree and optimistic nature against Gajeel's more serious and gruff personality would create an interesting dynamic. Maybe they're on a quest to find a powerful treasure in a new world created by the crossover.
Well, first of all, it should have a strong plot. For example, the reason for the crossover needs to be logical. If Gajeel is crossing over into another world or with other characters, there should be a good explanation like a magic spell gone wrong or a portal opening. Second, character development is crucial. Gajeel should grow or change in some way throughout the story. Maybe he learns a new skill or develops a new friendship. Third, the fanfic should stay true to Gajeel's character. He's known for his tough exterior and his loyalty, so any story should not make him act completely out of character. For instance, he wouldn't suddenly become a coward or overly sentimental without a proper backstory to support it.
One great gajeel crossover fanfic is 'Gajeel in Another World'. It has an interesting plot where Gajeel is transported to a different realm and has to adapt to new powers and challenges. The character interactions are well - written and it really showcases Gajeel's growth in a unique setting.
One great Levy and Gajeel fanfiction is 'A Bond Beyond Words'. It beautifully explores their relationship growth from rivals to lovers. The author does an amazing job of capturing Levy's intelligence and Gajeel's rough - yet - tender side.
Yes, there might be such fanfictions out there. The idea of crossing over Naruto and Fairy Tail universes to make them brothers is quite an interesting concept that some fanfiction writers might explore. It allows for a lot of creative interpretations, like how their different powers could interact or how their personalities would mesh in a shared story.
Well, in such a fanfiction, Gajeel would bring a whole new energy. He might be more rebellious as a youngster. His journey to find his place in Fairy Tail could involve getting into small scuffles with other members at first. But as time passes, he realizes that Fairy Tail is a place where he can belong. His growth could be shown through his changing attitude towards the guild's rules and values.
One aspect that could be explored in this fanfiction is Gajeel's growth in magic. As a kid joining Fairy Tail, he would be exposed to different types of magic and training methods. Maybe he starts off with his Iron Dragon Slayer magic being quite basic, and then with the help of the guild's masters and other members, he refines it. He could also learn new skills that complement his existing magic, which would not only make him stronger but also show his development within the guild.
Well, there's a fanfiction called 'Juvia's Heart, Gajeel's Soul'. It shows how Juvia's emotional side and Gajeel's tough exterior interact in a relationship. 'The Iron and the Rain' is a story where they go on an adventure together, and through that, their bond grows stronger. 'Shadows of Love' is about how they deal with their pasts while falling in love.
