In the fanfiction, Gildarts could meet Natsu and Igneel during a time of crisis. Maybe their town is under attack. Gildarts would immediately jump into action, and Natsu would follow suit, with Igneel guiding Natsu from the side. Gildarts might be impressed by the way Natsu and Igneel work together, as if they share a single mind. They could communicate without words, and Gildarts would try to learn from their unique bond. After the battle, Gildarts would offer to train Natsu further, seeing his great potential enhanced by his connection with Igneel.
Well, one possibility is that Gildarts could share some of his powerful magic techniques with Natsu. Since Gildarts is a very experienced wizard, he might see the potential in Natsu and offer some tips on how to better control his fire magic, which is similar to Igneel's. Maybe he could also tell Natsu some stories about his own adventures that would inspire Natsu to become even stronger.
It depends on how the author of the fanfiction has developed the plot and the characters. They could have given Natsu some special power - up or a unique situation that makes him stronger than Gildarts. For example, the author might have introduced a new form for Natsu that gives him an edge in combat, or perhaps they've weakened Gildarts in some way for the sake of the story. However, in the original series, Gildarts is extremely powerful, so this is a significant departure in the fanfiction.
Natsu could try his all - out offensive with his most powerful fire attacks. He might start with his Fire Dragon's Roar and then quickly follow up with a combination of punches and kicks enhanced with his fire magic. Another strategy could be to use his environment. If they're in a place with flammable materials, he can set them on fire to create distractions or additional sources of power for his attacks.
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.
Often, their relationship is depicted as a very strong father - son - like bond. Igneel is seen as the wise and powerful mentor to Natsu, guiding him in his journey to become a great 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.
When Igneel meets the guild in fanfiction, there are numerous possibilities. Firstly, there could be a cultural exchange of sorts. Igneel, with his different background, could introduce new ways of thinking and magic. Secondly, he might get involved in the guild's internal politics. He could help resolve disputes or support certain leaders within the guild. And finally, his arrival could attract unwanted attention from other forces, leading to a new wave of challenges for the guild.
It could be an enemy dragon. There are many rival dragons in the Fairy Tail universe, and if they see Natsu with Igneel, they might target Natsu to get to Igneel. Dragons can be very territorial and protective of their own, and an enemy dragon may see Natsu as a weak point to attack Igneel through.
