Igneel might start by showing off his power to intimidate some of the guild members at first. Then, he could gradually warm up and start teaching them about different forms of magic.
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.
Some of the more cautious members, like Erza, might be a bit wary at first. She would be concerned about how Igneel's presence might change the power dynamics within the guild and what his intentions truly are. But over time, as she sees his positive influence, she would likely warm up to him.
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.
He would probably recruit his friends first. Sasuke could be a great addition with his powerful Sharingan abilities. Sakura with her medical ninjutsu skills would be valuable for taking care of the guild members' injuries. Shikamaru, being intelligent and a great strategist, could plan out the guild's actions. And Choji, with his strength, could be useful in physical tasks or battles.
In fanfiction, the Combaticons might initially view Starscream as a nuisance. But if there's a common enemy, like a powerful Autobot force, they might be forced to work with him. Starscream could bring his aerial combat skills to the table, while the Combaticons contribute their combined strength. Their relationship could evolve from distrust to grudging respect as they fight side by side.
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.
One possibility is that they become friends immediately. The elf could be really friendly and show Harry around the elf village or something. Another is that they start off on the wrong foot. Maybe Harry accidentally offends the elf at first, but then they work through it.
Another interaction could be them collaborating on a project. Maybe they are in a situation where they need to build something or solve a mystery. Annabeth's strategic thinking combined with Estelle's fresh perspective could lead to an interesting and successful partnership.
In a 'naruto is igneel fanfiction', perhaps Naruto is transported to a world where Igneel exists. There, Igneel sees Naruto's potential and decides to train him. Naruto has to adapt to this new world and its rules while learning from Igneel. He could gain dragon - like powers, which he then combines with his ninja skills to face new and more powerful enemies.
In some fanfictions, Snape might give Hermione rare books from his personal collection to aid her in her studies. This shows that he respects her thirst for knowledge.
