In this type of fanfiction, a possible plot is that Naruto is sent to a dimension where time moves differently. He might age at a much faster rate, and he has to quickly master the ways of this dimension to find a way to reverse the time effect on him. Another cool plot could be that he lands in a dimension that is a mirror image of his own, but with opposite personalities for everyone. So he has to deal with a Sasuke who is overly friendly and a Kakashi who is always serious, which makes for a really strange and challenging adventure.
Well, Naruto might find allies among the outcasts of the new dimension. People who don't fit in with the mainstream society but have unique powers or skills. They could see Naruto as a kindred spirit and join forces with him. Also, if there are any beings in the new dimension that oppose the forces that brought Naruto there, they could be his allies. They might have their own reasons for wanting to help Naruto, like using his power to overthrow a tyrant in their dimension.
One interesting plot could be Naruto using his future knowledge to prevent some tragic events in the past. For example, he might stop the death of certain characters or change the course of a big battle.
One idea could be Naruto being transported to a dimension where chakra doesn't exist, but he discovers a new form of energy and has to learn to use it from scratch. This would force him to adapt his fighting style completely.
One interesting plot could be Percy finding himself in a world where the Greek gods have different forms or powers. For example, Zeus could be a benevolent king instead of the often angry god we know. Percy would have to navigate this new world, figure out how to use his own powers in relation to these changed deities, and perhaps find a way back home. Another plot could involve Percy being sent to a world that is a blend of different mythologies, like Greek and Norse. He'd have to deal with new creatures and gods from both mythologies, which would be a real challenge.
She could travel to a dimension where all the ninja villages are united. Naruko would be amazed at the peace and cooperation and might try to bring this concept back to her own dimension. It would be a story about her learning from this utopian - like place.
In fanfiction, if Naruto is sent to a different dimension, he might face all kinds of strange new powers and enemies. For example, he could encounter magic that is completely different from chakra. He would have to quickly adapt to survive. Maybe he'd find allies who are also lost in this new dimension and together they'd try to find a way back home while also dealing with the local threats.
In this type of fanfiction, a great plot can be Naruto going back and influencing the Third Hokage's decisions. For example, he could convince the Hokage to be more open - minded about new techniques and alliances. He might also focus on improving the living conditions in the village at an earlier stage. By doing so, he could potentially change the future of the entire Hidden Leaf Village and the shinobi world in general.
In some fanfictions, Ben might travel to a dimension where his family members have different personalities or abilities. This could lead to a lot of self - discovery for Ben as he has to deal with these new versions of his loved ones. He may also have to find a way to get back to his own dimension while facing challenges specific to that new dimension.
Well, a great plot might be that Spiderman travels to a dimension that's a post - apocalyptic world. In this world, he teams up with the few remaining survivors who have some unique abilities of their own. Together, they try to find a way to restore their world while Spiderman also looks for a way back to his own dimension. Or perhaps he travels to a dimension where the laws of physics are completely different, like he can run on water or fly without his webs. He has to adapt quickly to these new conditions and also face the threats in that dimension.
In an 'Avengers Another Dimension Fanfiction', a cool plot might involve a dimension where technology and magic are one and the same. So Iron Man's suit could be powered by both arc reactor energy and some sort of magic spell. Or a dimension where the Avengers are part of a gladiator - like arena, and they have to fight not only their usual foes but also other heroes from different universes just to survive and find a way back home.
