It could change the course of events significantly. Maybe Natsu would have had more guidance and become even stronger.
I'm not sure if there is a specific fanfiction with the exact title 'naruto is igneel fairy tail fanfiction'. Fanfictions can be quite diverse. It might be a very creative crossover where the author imagines Naruto in the world of Fairy Tail with a connection to Igneel. Maybe Naruto has some of Igneel's powers or characteristics in this fictional scenario.
One significance could be the emotional boost for Natsu. After so long without Igneel, having him back would be a huge source of comfort and strength. Natsu could become even more determined in battles.
Well, in this fanfiction, Igneel's return could bring a huge shift in power dynamics. His relationship with Natsu might be explored more deeply, like they could have some intense training sessions. Also, it might lead to new quests for the Fairy Tail guild as Igneel's knowledge could be used to combat stronger enemies.
Lucy could be extremely excited. After all, finding Igneel is like stumbling upon a legend come to life. She would likely be in awe of his presence. She might immediately think about how this discovery could benefit her friends in the Fairy Tail guild. She could also be very respectful and try to approach Igneel in a friendly manner.
In the Fairy Tail universe, Igneel is extremely powerful with his fire - based magic. However, Acnologia is known as the most powerful dragon. I think Acnologia would win. His power is on a different level and he has shown to be nearly invincible in most battles.
Well, in a Fairy Tail fanfiction with Saitama, he would probably be quite a comical addition at first. The Fairy Tail members would be astounded by his power. He might not fully understand the magic - based society at first, but his sheer strength would earn him respect. And he could also form some interesting friendships. For example, he could bond with Natsu over their love for a good fight, although their fighting styles are completely different. Saitama's no - nonsense attitude might also influence the more hot - headed members of Fairy Tail to be more focused.
It could lead to new and interesting storylines. Fanfiction often explores alternative scenarios and character developments not seen in the original.
One great fanfiction could be about Natsu's training with Igneel. In it, Igneel imparts not only fire - based combat skills but also valuable life lessons to Natsu. Another might focus on a time - travel scenario where Natsu goes back in time and meets a younger Igneel, and they form a different kind of bond. There are also fanfictions that explore Igneel's perspective on Natsu's growth as a wizard.
One popular storyline is about Natsu's journey to become stronger in the memory of Igneel. He often faces tough battles and overcomes them with the power Igneel instilled in him. Another is where Natsu discovers hidden secrets about Igneel's past that change his perspective on his own life and powers. And sometimes, there are fanfictions that feature Igneel coming back in some form to guide Natsu further in his adventures.
One possible plot could be that Igneel's arrival in Fairy Tail brings a new level of power and protection. He could start training the mages in new and powerful dragon - slaying magic, making Fairy Tail even more formidable against their enemies.
