In the fanfiction, Natsu vs Zeref while Fairy Tail watches could be an epic showdown. Natsu's natural instinct as a dragon slayer would be in full force. He would be constantly on the move, attacking Zeref with his fire - based attacks. Zeref, being the complex and powerful villain, would likely have some devious plans up his sleeve. He might try to manipulate the environment, creating dark and dangerous situations. The Fairy Tail onlookers would add an interesting dynamic. Some might be worried sick for Natsu, while others would be in awe of his courage. Their presence could also lead to some unexpected plot twists, like if one of them somehow manages to interfere in the fight, either accidentally or on purpose to help Natsu.
Well, it could be that Natsu's rage against Zeref is a major factor. Natsu has a long - standing grudge against Zeref for all the pain and suffering he has caused. This could fuel his attacks and make him more reckless than usual. However, Zeref is no pushover. He might try to use Natsu's anger against him, by setting up traps or counter - attacks that rely on Natsu's over - eagerness. And the Fairy Tail members watching could be a source of both distraction and inspiration for Natsu. Their cheers and shouts of support might give him the extra push to keep going, but also make him worry about their safety, which could affect his performance in the fight.
In this fanfiction scenario, one possible thing that could happen is that Natsu's determination to defeat Zeref might be put to the ultimate test. Natsu has always been a fighter with a strong will, and facing Zeref, he would have to dig deep. Zeref, on the other hand, being extremely powerful, might initially have the upper hand. But Natsu could tap into some hidden power, perhaps related to his dragon slayer magic in a new and unexpected way. Maybe he would get some kind of emotional boost from his friends in Fairy Tail who are watching, which gives him the edge he needs to turn the battle around.
Perhaps the Fairy Tail members watching will have different reactions. Some might be worried for Natsu, especially those who are close to him like Lucy or Happy. Others, like Erza, might be more focused on analyzing Natsu's moves and Zero's counter - attacks. And there could be some comic relief from the likes of Gray, making snarky comments while still being engaged in the fight between Natsu and Zero.
One exciting moment could be when Natsu first unleashes a new and powerful attack against Zeref. Maybe it's a combination of his dragon slayer magic and some newfound strength he has gained. Another exciting part might be when Zeref counters with a really dangerous and dark spell that Natsu has to struggle to avoid. And of course, the moment when the Fairy Tail members react with shock or excitement to these powerful exchanges between the two would also be thrilling.
If Natsu and Zeref join Fairy Tail in fanfiction, it would change the dynamic of the guild completely. The other members would have mixed reactions. Some might be distrustful of Zeref due to his past actions. However, as time passes, they could see the good in him. Natsu and Zeref together could attract a lot of attention from outside forces. Enemies might target Fairy Tail more because of their combined power. But also, they could inspire the guild to become even stronger, with everyone striving to keep up with their new powerful comrades.
I haven't read this particular fanfiction yet. But generally, in a scenario where Fairy Tail characters watch Natsu fight Zeref, it could be filled with intense emotions. Natsu's determination and his unique powers would be on full display. And the reactions of the other Fairy Tail members would add depth to the story, whether it's shock, pride, or worry.
One possible plot twist could be that Zeref actually doesn't want to fight Natsu seriously and has some hidden agenda. Another could be that Natsu discovers a new power during the fight that is related to his past or his true identity.
Well, it depends on the specific fanfiction. Some fanfictions do make Zeref and Natsu brothers. This can create some really cool plot twists. For instance, it could change how Natsu views his powers if he discovers he's related to Zeref. And it might also make Zeref more protective or possessive of Natsu in a different way than in the original story. It's a concept that allows for a lot of creativity in the fanfiction world.
Their relationship could develop differently if Natsu didn't initially see Zeref as an enemy. Instead of the typical animosity, Natsu could approach Zeref with curiosity. Maybe he wants to understand why Zeref created him and what his purpose really is. This could lead to a more cooperative relationship from the start.
One of the most exciting moments is when Natsu's intense fire magic clashes with Jellal's powerful Heavenly Body Magic. The visual display of their powers colliding is just amazing. Another great moment could be when they exchange some intense verbal sparring before the actual fight, adding more tension to the encounter.
The unique interactions. When Fairy Tail characters watch Natsu vs Zero, their reactions add depth. For example, if Lucy gasps or looks worried, it shows her care for Natsu.
Natsu could end up teaming up with some unexpected allies from Tartaros. Maybe there are some members who have a change of heart and decide to help Natsu fight against the more evil elements within their own organization.
