One interesting concept could be the use of the mind transfer jutsu for espionage. For example, a character could transfer their mind into an enemy's body to gather intelligence. Another concept might be the moral implications of using such a jutsu. What if it was misused to frame someone? And also, the idea of a character getting stuck in another's body due to a failed mind transfer jutsu can lead to some really comical or tense situations in fanfiction.
Naruto himself is often involved. Since he's the main character, fanfiction writers like to explore how he would use or be affected by the mind transfer jutsu. Sasuke is another common one. His complex personality and powerful abilities make for interesting scenarios when combined with the mind transfer jutsu. Kakashi too, as he is a very intelligent and experienced ninja. Writers might explore how he would use the jutsu for strategic purposes.
He might be initially shocked and confused. Since Naruto is not used to having someone else's mind in his body, he could struggle to control his actions at first.
A more complex plot could be that an enemy uses a device to force Ino to transfer her mind into Naruto. The enemy then plans to use Naruto's body with Ino's mind to infiltrate Konoha. Ino has to find a way to communicate with Naruto's consciousness and stop the enemy's plan from within Naruto's body.
One type of Naruto mind control jutsu fanfiction could involve a villain using the jutsu in a new and devious way. For example, they might target the Hidden Leaf's most powerful ninjas to turn them against their own village. This would create a huge conflict as the heroes would have to fight their brainwashed comrades while also trying to find a way to break the mind control.
Some fanfictions might focus on the psychological effects of the mind control jutsu. For example, if a character is under mind control for a long time and then is freed, how do they deal with the memories of what they did while controlled? It could be a very emotional and character - driven story. Maybe they struggle with guilt or fear of being controlled again.
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.
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.
In Naruto fanfiction, cheat codes can drastically change the use of jutsu. They might allow a character to instantly master a jutsu that usually takes years of training. For example, a cheat code could give Naruto the ability to use the Rasengan without any training from Jiraiya. It's a fun concept that adds an interesting twist to the Naruto universe.
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.
