In some fanfictions, Acnologia is made out to be Natsu's father. But this is not part of the original canon of the Fairy Tail series. Fanfiction writers often like to create such unexpected family relationships to add new twists to the story.
Yes, there might be such a fanfiction in the vast world of fan - created stories. Fanfiction often takes characters from different universes and creates unique and sometimes wild scenarios like this one.
It's possible that in this fanfiction, Lucy and Acnologia meet in a neutral territory. Lucy, with her kind heart, tries to communicate with Acnologia. Acnologia, who has been alone for a long time, is initially hostile. But as Lucy persists, she manages to break through his tough exterior. They might then share stories about their pasts, with Lucy talking about her guild and Acnologia about his past as a dragon.
The identity and background of Lucy's father were described differently in different documents. In document 1, Lucy's father was an employee of a fallout shelter company. He took Lucy away during a mission and became the manager of a fallout shelter. He had launched a nuclear bomb to destroy Shayin City and was taken away by Mrs. Flame for interrogation. In document 3, Lucy's father was Jorde Hartfilia, a wealthy businessman. However, after his wife passed away, his relationship with his daughter became bad, causing her to run away from home. In document 5, Lucy's father was a man who abandoned Lucy's youngest daughter in Ode to Joy 5 in order to remarry quickly. In other documents, Lucy's father's identity was not mentioned.
In summary, there were different descriptions of Lucy's father's identity and background, and it was impossible to get an accurate answer.
Maybe there's a group of dragon hunters. They view Acnologia as the ultimate prize and would do anything to capture him. When they see Lucy interacting with Acnologia, they consider her a traitor to humanity and try to take them both down. They could be the main antagonists as they constantly pose a threat to Lucy and Acnologia's new - found relationship.
It could be about Acnologia teaching Lucy some powerful magic. Maybe he sees potential in her and decides to train her in combat magic. For example, he might show her how to better control her celestial spirits in battle situations.
Well, it depends on the specific fanfiction. Some fanfictions might make ACNOLGIA Lucy's father for the sake of a unique plot. Others may not follow this idea at all. There are so many different ways fanfiction writers can take the story, but it's definitely an interesting concept that some writers have explored.
Lucy could become more confident. With Acnologia's training, she might gain a new level of self - assurance in her abilities. For instance, she could stand up to stronger opponents without hesitation.
It would be a very strange and interesting mix. Naruto's energetic and determined nature would contrast with Acnologia's more menacing reputation. As Wendy's father, Naruto - as - Acnologia might be a protective figure, teaching Wendy his ninja skills along with any dragon - related powers from the Fairy Tail world.
One common theme is the exploration of Natsu's new - found heritage. Another is the power struggle within Natsu as he grapples with having the blood of a powerful and feared dragon like Acnologia. Also, there might be themes of redemption for Acnologia through his relationship with Natsu.
