Definitely Gai. His whole shtick is about speed and he has amazing techniques like the Eight Gates. He can teach a lot about physical speed and the willpower needed to push one's limits. Also, Minato is a great choice. His Flying Thunder God Technique requires incredible speed and reaction time, so he could offer valuable insights.
One common theme is self - discovery. Characters with the speed bloodline often have to figure out the full extent of their powers. For example, they might not know they can use their speed for time - space manipulation at first.
One possible fanfiction could involve Naruto being transported to the Young Justice universe and somehow getting connected to the Speed Force. Maybe he gains super - speed abilities and has to learn how to control them while also dealing with the threats in the Young Justice world. He could team up with the Young Justice characters, like Robin or Kid Flash, and use his ninja skills along with his new speed powers to take on villains.
In fanfiction, Naruto's super speed gives him an upper hand in combat. He can quickly respond to any threat. If an enemy launches a long - range attack, he can dash towards them and stop it before it reaches its full power. It also makes him a more effective leader in some stories. When his team is in trouble, he can get to them in no time and turn the situation around. This speed also helps him in evading traps or dangerous situations in the story's plot.
Sasuke could be his rival. Sasuke is known for his competitiveness and would see Naruto's entry into the Need for Speed world as a challenge. He would use his Sharingan to analyze Naruto's moves and try to outdo him on the race track.
In some 'Naruto Lightning Speed Fanfic', the author might create a new character who has an innate ability to control lightning at an extraordinary level. This character could either be an ally or an enemy to Naruto. For instance, the new character challenges Naruto to a battle to prove who is the true master of lightning - speed combat.
The story could start with Naruto getting a mysterious invitation to a Need for Speed event. Once there, he discovers that the races are not just about speed but also about strategy and teamwork. He forms a crew with some unlikely characters. Together, they face off against a powerful racing syndicate that has been cheating in races. Naruto uses his determination and ninja techniques to expose the syndicate and win the championship.
Well, in this kind of fanfiction, some might write about special training grounds. These could be places with unique gravitational or chakra - infused environments. Training in such areas would force the body to adapt and become faster. Additionally, diet and rest play a role. Just like in real - life athletics, proper nutrition and sufficient sleep can help a ninja in the fanfiction recover faster and perform better in speed training.
Well, in certain fanfictions, Naruto's super speed is often linked to his chakra control. By manipulating his chakra in a unique way, he can enhance his leg muscles' power, allowing him to run or move at incredible speeds. This super speed also enables him to perform his signature jutsus more effectively, like the Rasengan. He can close the distance between him and his target very fast and land the Rasengan before the enemy can react.
