In Naruto fanfictions, Raiton Affinity usually means a character has a natural inclination towards using lightning - based jutsu. It can be shown as an easier time learning Raiton techniques or having more powerful Raiton attacks.
One good Naruto Raiton Affinity fanfiction is 'The Raiton Prodigy'. It focuses on a character with a strong Raiton affinity and their journey to master it. Another is 'Raiton's Edge' which has some really cool battles involving Raiton techniques.
A 'Solar - Flare Rasengan'. Naruto could combine his wind - style chakra with some kind of solar - based energy he discovers. This jutsu would be like a super - charged Rasengan that emits a blinding light as well as powerful wind - based damage.
There could be a jutsu that allows for instant teleportation across long distances. This jutsu might be a new discovery in the fanfiction world, perhaps created by a character who has been experimenting with space - time ninjutsu. They might use it to quickly get in and out of battles or reach far - off places in a blink.
It could be a new form of Rasengan. Maybe Naruto discovers a way to combine different elements with the Rasengan more effectively, like adding lightning to it for a more powerful and faster attack.
Maybe Sasuke. Although they are rivals, they also have a deep bond. Sasuke might have come across a unique jutsu during his travels and decide to teach it to Naruto so that they can both become stronger and better protect their village.
It could be Naruto himself who discovers and uses the Katon Hijingakure no Jutsu in the fanfiction. Since he's always exploring new jutsus and pushing his limits.
He might learn a time - traveling jutsu. This would be really cool as it could allow him to go back and change certain events in the Naruto world, or gain knowledge from the past to use in the present battles.
Well, in this fanfiction, the Katon Hijingakure no Jutsu might have unique characteristics such as a more intense and hotter flame compared to the regular Katon techniques. Maybe it also has some special shape or movement pattern that is distinct from other fire - based jutsus in the Naruto universe.
The Naruto barrier jutsu in fanfiction often serves different purposes. It can be used as a defensive mechanism for protecting allies during a large - scale battle. Or it could be a part of a trap, where Naruto lures enemies inside the barrier and then uses other jutsus to defeat them. Fanfiction writers have a lot of creative freedom with this jutsu.
