Kakashi could be a key character in the fanfiction. As Naruto's former teacher, he could provide guidance and set up the extreme training regimens for Naruto. Also, characters like Jiraiya might be present. Since he trained Naruto in the original series, he could play an important role in this extreme training scenario, perhaps teaching Naruto some advanced toad - related techniques.
Other common characters could include Naruto's friends like Shikamaru, who might offer their own insights or help in different ways. For example, Shikamaru's intelligence could be used to strategize the training, or he could create some kind of mental - training challenges for Naruto to overcome during his extreme training.
Jiraiya is often a common character. Since he was Naruto's teacher and had knowledge of sage training himself, he might appear in the fanfiction to guide Naruto further. Another one could be Kakashi. He is always looking out for Naruto and could be involved in the training in some way, like providing strategic advice.
Obviously, Naruto is a top choice as he has so much potential for growth and development in training. Sakura also appears frequently as she is constantly striving to improve her skills. Rock Lee is another common character in these fanfictions because of his intense dedication to training and his unique fighting style. His training methods can be really interesting to explore in fanfiction.
Obviously, Naruto is the central character. But there are also often other characters like Jiraiya. Since Jiraiya was Naruto's mentor in the original story and had knowledge about sage mode, he often appears in fanfics to guide Naruto in his training. Another common character could be Kakashi. He may offer some advice or support to Naruto during the training process.
One interesting plotline could be Naruto finding a new and extremely challenging training method that unlocks a unique and powerful jutsu. For example, he might discover a hidden cave with ancient training scrolls left by a forgotten ninja clan.
There could be new characters created specifically for this fanfiction. For instance, an old hermit who lives in the mountains where Naruto is training and has some ancient knowledge of ninjutsu. Or perhaps a group of rogue ninjas who try to disrupt Naruto's training. Also, characters from other villages that Naruto might interact with during his travels, such as a young ninja from the Sand Village who is also on a similar training journey.
Well, in Naruto Shippuden extreme fanfiction, Naruto and Sasuke are at the top of the list for obvious reasons. Their rivalry and friendship are central to the series, and fans like to explore different aspects of it. But other characters like Itachi also gain a lot of popularity. His tragic backstory and powerful abilities make him an interesting subject for fanfictions. Additionally, Sakura is popular as she is a strong female character, and many fanfictions focus on her development further, either as a medic - nin or in combat situations.
Naruto himself is often a popular character in Naruto Extreme Quake fanfiction. His never - give - up attitude and powerful jutsus make him a central figure for many storylines.
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.
The main characters are Naruto and Jiraiya. Naruto is the young and eager - to - learn ninja, and Jiraiya is his experienced mentor.
Obviously Naruto himself is extremely popular. Since the fanfiction is about his intense training, he is the central focus. Sasuke is also popular. His rivalry with Naruto often means he is included in training scenarios, either as a partner sparring with Naruto or as someone Naruto is trying to outdo. Kakashi is another popular character. As Naruto's teacher, he is often involved in guiding Naruto through his intense training.
