In that fanfiction, it might be designed that way. Naruto has incredible powers in his own series, like his various jutsu. If translated into the Fairy Tail world in fanfiction, his skills could potentially make him very powerful. But it also depends on how the author of the fanfiction interprets and balances the power systems of both universes.
One idea could be a crossover where a Naruto character, like Naruto himself, somehow ends up in the Fairy Tail world and meets a cute mage, perhaps Lucy. They could team up on a mission and Naruto's unique ninja skills combined with the magic of the Fairy Tail mage would make for an interesting story.
One great 'Fairy Tail Mad Mage' fanfiction is 'The Lost Mage of Fairy Tail'. It tells a story of a mage with extraordinary powers who was lost for years and now returns to the guild. Another interesting one is 'Mad Mage's Redemption'. It focuses on a mad mage trying to make up for his past wrongs within the Fairy Tail world.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Naruto the Cutest Mage Fairy Tail' and you'll find a variety of stories, some might focus on crossovers between Naruto and Fairy Tail with the unique concept of Naruto as a mage.
His chakra. Chakra is like the energy source in Naruto's world. In the fanfiction, this chakra could be translated into a very powerful form of magic in Fairy Tail. It gives him the ability to perform various powerful techniques, much like mages in Fairy Tail use their magic.
One great 'Fairy Tail Gravity Mage' fanfiction is 'Gravity's Ascent'. It really delves into the potential of a gravity mage in the Fairy Tail universe. The main character, a newly discovered gravity mage, has to navigate through the guild's politics while also mastering their powers. It has some really cool action scenes where the use of gravity magic is quite creative.
To make the fanfiction engaging, create some conflict. It could be a conflict between the two worlds, like the ninjas in Naruto thinking the magic users from Fairy Tail are a threat. Or it could be an internal conflict within a character, such as the cute mage struggling to control their powerful magic while also trying to fit into the Naruto world. Also, don't forget to add some humor and heart - warming moments to keep the readers interested.
Well, in fanfiction, anything can happen. But Naruto being a weak Fairy Tail mage seems a bit off. Naruto is a powerful ninja with a strong will. In Fairy Tail, mages also rely on their willpower to some extent. Naruto could potentially draw on his ninja skills and combine them with magic in unique ways. For example, his shadow clone jutsu could be adapted into some form of magical clone spell. His Rasengan could be transformed into a magic - based attack. So, he may face some initial challenges in understanding magic, but he's not likely to be weak.
The popularity of 'Fairy Tail Gravity Mage Fanfiction' lies in the fact that it allows for a lot of creativity. Fairy Tail already has a rich world full of magic, and adding a unique magic like gravity magic gives writers a chance to create new and exciting stories. It also lets fans explore different character arcs that might not be possible in the original series.
One interesting concept could be the combination of Naruto's ninja abilities with the magic system of Fairy Tail. For example, Naruto's shadow clones might be used in a unique way when combined with Fairy Tail magic, like using clones to perform multiple spell - casting simultaneously.
