In fanfiction, Mavis' brother can be portrayed in various ways. Some might depict him as a protective figure, always looking out for Mavis before her misfortunes. He could be a strong magic user, with unique abilities that are different from Mavis' own.

Well, one way it could work is if there was some sort of multiverse crossover. Maybe in a strange twist of magic, Naruto could be transported to the Fairy Tail universe and end up related to Mavis. It would be really interesting to see Naruto's ninja skills combined with the magic of Fairy Tail. He could teach the Fairy Tail guild some unique combat techniques.
Naruto could be a protector. Just like he protected Konoha in his own world, he would protect Mavis and the Fairy Tail guild. His combat skills would be a great asset.
In fanfiction, the idea of Mavis and Zeref having a child often leads to very complex and interesting storylines.

One way could be through a crossover of magic and ninjutsu. Maybe Mavis's brother could have a unique power that is similar to a ninja ability in Naruto.

Naruto has shown incredible feats of strength, speed, and endurance. He has defeated some of the most powerful villains in his universe. But Mavis is no slouch either. Her Fairy Law is a very powerful spell. If we consider their growth potential, Naruto has the ability to constantly get stronger by unlocking new forms of his power, like Sage Mode and later the forms related to the tailed beasts. Mavis, on the other hand, has a deep knowledge of magic that could potentially allow her to counter any of Naruto's attacks. It really depends on the situation, the location, and how well they know each other's abilities.
Well, in many fanfictions, their relationship might start with Natsu being a bit in awe of Mavis as she is a very important figure in Fairy Tail's history.
