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 a fanfiction where Lucy finds Igneel, it could start with Lucy having a vision about Igneel. She then becomes determined to find him. When she does, Igneel could be in a hidden lair. Lucy and Igneel might form an unexpected bond. Igneel could teach Lucy some powerful dragon - slayer magic, which would be a huge advantage for her. And she could use this new power to fight against the dark forces that are threatening the Fairy Tail 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.
The guild as a whole would likely mobilize. Erza would start formulating a strategic plan. She'd consider the strengths and weaknesses of Acnologia and figure out the best way to approach the situation. Gray would also be ready to fight, using his ice - make magic to support the rescue mission. They would all be united in their determination to get Lucy back safely.
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.
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.
The guild would likely be ecstatic. Gray would probably make some snarky comment about Natsu finally growing up, but deep down he'd be happy for his friend. Erza would be all for it and might start planning the wedding immediately, giving orders to everyone in the guild to help out.
It could change the course of events significantly. Maybe Natsu would have had more guidance and become even stronger.
Lucy might be really surprised at first. But then she'd probably blush and say yes. After all, she and Natsu have a strong bond already.
Natsu would probably be really excited at first. He'd be all over the place, asking a million questions and making sure Lucy is okay. Happy would be right there with him, trying to help in his own little Exceed way. Erza would be very protective. She'd make sure Lucy follows all the proper precautions and would offer to train her gently so she doesn't lose her fighting edge during pregnancy. Gray might be a bit awkward at first but would soon warm up and offer his support, like helping with any heavy lifting around Lucy's place.
