One possible fanfiction could be about Erza Scarlet getting a special tattoo by Nuarto that gives her some unique power in the Fairy Tail universe. Maybe it's a tattoo that has a connection to her past or unlocks a hidden magic ability.
The significance could be related to her heritage. Perhaps Erza discovers that she has a long - lost family connection, and the tattoo by Nuarto is a traditional mark of that family. It could then be a source of new spells or abilities that are specific to her family's magic, which she can use to help Fairy Tail in their adventures.
Erza Scarlet is a very strong and complex character in Fairy Tail. She is known for her strict and disciplined nature. She has a tragic backstory where she was enslaved at a young age on the Tower of Heaven. But she overcame that and became one of the most powerful mages in the guild. She is often seen leading the charge in battles and is respected by all her guildmates for her strength and leadership.
I'm not entirely sure if there are Naruto fanfictions specifically about Erza Scarlet from Fairy Tail and her tattoos. It depends on the creativity of the fanfiction authors. Some might see the potential in mixing these two different anime universes and come up with interesting stories involving Erza's tattoos in a Naruto - like setting. You could start by looking on popular fanfiction websites and using relevant search terms.
One of her major achievements was helping to defeat the dark guild Phantom Lord. Her strength in battle was crucial in protecting Fairy Tail. Another significant thing was her role in the Tower of Heaven arc. By facing her past and the people who once enslaved her, she not only freed herself but also the other slaves there. It was a huge step in her character development as well as a great victory for justice.
One possible fanfiction idea could be that Erza decides to cut her hair as a symbol of a new beginning. Maybe she has just overcome a great battle or a personal struggle, and she wants to show that she is a changed person. The haircut could be a short, stylish bob that shocks her guildmates at first but then they grow to love it as it represents Erza's newfound confidence.
In this 'scarlet destiny fairy tail fanfiction', it could be that the scarlet represents a symbol of passion or a powerful force. The story might be about a character who discovers their true destiny which is linked to this scarlet element. They may start off as an ordinary member of the Fairy Tail guild but as they uncover the secrets behind the scarlet destiny, they grow in power and become an important figure in the guild's future.
Perhaps in the fanfiction, Aquarius Nuarto is sent on a special mission by the Fairy Tail guild. This mission could be to retrieve a magical artifact that has been lost underwater. Along the way, she meets new characters, some of whom become her allies and others her enemies. She uses her water - based magic skills and her wits to complete the mission.
Another fanfiction concept could be that Erza somehow ends up in the Naruto universe. She might join Naruto's team for a mission. Erza's strong sense of justice and her powerful magic would be really interesting to see in the context of Naruto's world. For example, she could use her armor magic to help Naruto and his friends in a battle against a powerful enemy.
Well, you could start by having a character from Fairy Tail accidentally stumble into the world where Kurama and Kyuubi exist. Then, they discover a connection to the Nuarto world through some ancient magic or prophecy. And from there, the story can unfold as they try to find their way back home while also dealing with the powers and politics of these different worlds.
In some fanfictions where Erza dies, it could lead to a dark and tragic turn for the Fairy Tail guild. Her death might cause the other members to question their strength and purpose. For example, Natsu might be consumed by a desire for vengeance against the ones who caused her death.
