In the fanfic, Naruto could use the Chidori to save his friends who are trapped by an enemy's powerful jutsu. Since the Chidori is a very fast - moving and piercing attack, he could break through the barriers set up by the enemy. He might also face some internal struggle as using the Chidori goes against his normal style of ninjutsu.
One possible plot could be that Naruto discovers the Chidori technique while training in a secret area. Maybe he stumbles upon some old scrolls left by Kakashi. He then has to train hard to master it, facing difficulties like controlling the lightning chakra. As he progresses, he combines it with his own unique Rasengan, creating a new and powerful jutsu.
In a more creative fanfic, an ancient ninja who was the originator of the Chidori technique could appear. This ninja could be brought back to life through some sort of magic or jutsu. He sees Naruto's pure heart and decides to pass on the Chidori knowledge to him, believing Naruto will use it for good.
One possible plot twist could be that Naruto has a really hard time controlling the Chidori at first. Since his chakra nature is different from Sasuke's who originally used Chidori. He might accidentally release too much chakra and the Chidori becomes a much larger and more uncontrollable form, causing chaos during his training sessions. Another twist could be that when Naruto finally masters it, it takes on a unique form because of his Uzumaki chakra. It might have some kind of sealing ability added to it, which is different from the traditional Chidori.
Well, one possibility is that Naruto discovers Myrtenaster in some sort of alternate dimension or during a strange mission. He might initially struggle to figure out how to use it, but with his determination, he starts to unlock its powers. Maybe he uses it to fight new and powerful enemies that are immune to his regular jutsu.
In a fanfiction like this, the plot might involve Naruto struggling to master both techniques. He could start by observing Sasuke use the Chidori and then try to incorporate its lightning - based power into his own jutsu. For the Rasengan, he might have new insights while training, perhaps finding a way to combine it with the Chidori for an even more powerful attack. Along the way, he would face challenges like controlling the chakra flow for both techniques and dealing with opponents who are also after these powerful jutsus.
The plot might revolve around Naruto using Mokoton to build a new village. With his godlike powers, he can shape the wood into perfect houses, defensive structures, and beautiful gardens. This new village could be a place of peace and harmony, attracting people from all over who are seeking a better life. And Naruto would be the leader, using his powers to protect and nourish the village.
One possible plot could be that Naruto uses Chibaku Tensei to stop an extremely powerful enemy. Maybe he has to make a great sacrifice to master this powerful jutsu first. He might have to isolate himself to train in a special place and learn about the nature of the Chibaku Tensei from ancient scrolls or a hermit. Then, when the enemy arrives, Naruto uses the Chibaku Tensei, creating a huge gravitational pull that traps the enemy. However, this also takes a toll on his body as it's not a jutsu he's used to using.
In this fanfic, the plot could center around Naruto being given the claymore sword by a mysterious figure. The sword has a connection to his family that he doesn't know about. Using the sword, Naruto starts to have strange dreams. These dreams lead him to uncover secrets about his past and the future of the ninja world. He must learn to use the sword's power to face a new and dangerous threat that is emerging.
In a fanfic where Naruto knows the Chidori, it could change the power dynamics in battles significantly. Naruto's already vast chakra reserves combined with the piercing and fast - acting nature of the Chidori would make him an even more formidable opponent. He could use it in close - quarter combat situations, perhaps integrating it with his Shadow Clone Jutsu in creative ways. For example, he could have clones perform the Chidori from different angles, catching his enemies off - guard.
Well, in a Naruto using lightning fanfic, it could be that Naruto is in a situation where only lightning - based attacks can save the day. Maybe he's in a fight against an enemy who is immune to all other types of ninjutsu. So, he has to quickly develop and use his lightning skills in innovative ways. For example, he could combine his Rasengan with lightning chakra to create a super - powerful Lightning Rasengan.
