In some fanfictions, Erza's father could be a powerful mage who was lost in a great battle against dark forces. His absence then becomes a driving force for Erza's growth and her determination to fight evil.
One idea in fanfiction could be that Erza's father was an outcast mage. He might have had some unique magic abilities that were feared by the mainstream magic community. This led to his disappearance, and Erza unknowingly inherits some of his powers, which she discovers gradually in her adventures.
Maybe it's because they come from different fictional universes with very different values. Naruto is from a world of ninjas where loyalty to the village and personal growth through hard training are emphasized. Erza is from Fairy Tail with a more guild - centered and magic - based world. Their different outlooks and ways of doing things might clash in the fanfiction, leading to Naruto's hatred.
One possible plotline could be the redemption of Jellal. After all his past wrongdoings, he tries to make amends and prove himself worthy of Erza. Their kiss could be the moment when Erza finally fully accepts his transformation and they start a new chapter together.
One possible plotline could be that Erza sacrifices herself to save her guildmates from a powerful dark magic attack. She stands in the way, knowing it will cost her life, but she does it to protect those she loves.
Well, their child could be a symbol of hope in the fanfiction. Since Erza and Jellal have such complex pasts, the child might bring a new era of peace between different factions. For example, the child could have the power to bridge the gap between the Magic Council and the independent guilds. Also, the child's appearance might be a mix of Erza's red hair and Jellal's mysterious eyes, making it stand out in the Fairy Tail world.
Another way is to create a magical encounter where Erza is able to communicate with her father's spirit or a projection of him. Through their conversations, the depth of their relationship can be explored. This can include things like her father's hopes and dreams for her, and any regrets he may have had before his disappearance or death.
The girl OC could have been a street performer before joining Fairy Tail. Her guitar was her only means of survival. One day, she witnessed a Fairy Tail mage doing a great deed. Inspired, she decided to seek out Fairy Tail. The guitar has seen her through tough times on the streets, and now in Fairy Tail, it becomes a symbol of her journey from being alone to being part of a big family. She uses the music from her guitar to tell her story to the other members of the guild.
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.
The guild would become more protective. Members like Gray and Lucy would probably offer their help in various ways, like helping with baby - proofing their living quarters or giving advice on parenting. It would also add a more family - like atmosphere to the guild. There would be more anticipation and excitement for the new arrival.
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.
Perhaps the fanfiction could start with Jellal proposing to Erza in a very romantic way, like on top of a mountain overlooking a beautiful sunset. Then, the preparations for the wedding could be filled with some comical moments, like Natsu trying to help with the decorations but making a mess. After they get married, they might go on a honeymoon to a far - off land, where they encounter some old enemies who are now reformed and they all work together to solve a new mystery in that land. The fanfiction could end with them coming back to Fairy Tail stronger than ever and ready to face whatever comes next as a married couple.
