There's a chance that Natsu meets a strange being that has the ability to manipulate time in the other dimension. This being could either help Natsu by sending him back to his own dimension or cause him more trouble by sending him to different points in time within that dimension, creating a complex and exciting adventure for Natsu.
He might meet a powerful wizard who is the ruler of that dimension. This wizard could initially be hostile towards Natsu, seeing him as an intruder, but later they could become allies.
Natsu could meet a group of rebels in the new dimension. These rebels are fighting against an oppressive regime in that dimension. Natsu, with his sense of justice, would likely join them in their fight. He would also learn about their unique culture and way of life during this time.
Well, perhaps Natsu could find himself in a dimension where magic works completely differently. He might have to learn new ways to use his fire magic or even discover new types of magic altogether. Maybe he meets alternate versions of his friends who have different personalities due to the different environment of that dimension.
One common theme is self - discovery. When Natsu meets another version of himself, he often learns new things about his own capabilities and personality. Another theme is cooperation. Since they are essentially the same person, they have to learn to work together despite their initial differences.
There's a great piece of 'natsu meets natsu dimension travel fanfiction' where Natsu travels to a parallel dimension and meets another version of himself. This other Natsu has different magical powers. They end up teaching each other new spells and techniques while trying to find a way to close the rift between their dimensions. It's really exciting to read how they interact and grow together.
I'm not sure who exactly Natsu is just from 'natsu reads fanfiction'. It could be a normal person who just enjoys reading fan - made stories. Maybe it's a nickname for someone within a particular fan community.
One possible plot could be that Natsu and Lucy meet in a completely new and unexpected place, like a parallel magical world. They have to rely on each other to find their way back home while also uncovering the secrets of this strange new world.
In the 'natsu went mia in war fanfiction', Natsu is presumably a central or important character. He could be a hero - type figure who was expected to play a significant role in the war. It's possible that he has some special abilities or traits that made his presence crucial. Since he went MIA, the whole story might be about his friends or allies trying to find him or dealing with the aftermath of his disappearance. It could also be that Natsu is a character with a complex backstory, and his going missing in action is a key event that will unfold and reveal more about his past, his relationships, and the overall world of the fanfiction.
It could be a time - traveling version of Zeref. He might be trying to stop Natsu from changing things in the past that could potentially lead to his own downfall in the future.
Lucy could be a main character. She was always close to Natsu in the original Fairy Tail. So when Natsu returns as an 'ex' and meets the guild again, she would likely play a big role in how he is received and in the development of the story.
One of the senior and more experienced members of the guild. They have seen a lot and know how things should be done in the guild. If Natsu acts in a way that goes against their long - established ways, they would not hesitate to berate him.
He could marry an original character created specifically for the fanfiction. This character could be a powerful mage from a far - off place who crosses paths with Natsu during one of his adventures.
