In addition to Naruto and Asuma, Shikamaru could also play an important role. Since Shikamaru was Asuma's student, he might be involved in the training sessions in some way. Maybe he would act as a sparring partner for Naruto or offer his own insights on the training techniques taught by Asuma.
Another possible character could be Kurenai. As Asuma's love interest, she might be shown in the fanfiction. She could be a source of support for Asuma during the training process, or perhaps she could also contribute to Naruto's training in some aspects, like teaching him about chakra control or stealth, skills that she is proficient in.
Obviously, Naruto and Asuma would be the main characters. Naruto, the protagonist of the Naruto series, is the one being trained. And Asuma, a respected jonin in the Hidden Leaf Village, is the trainer.
The main characters would be Naruto and Hiruzen. However, we might also see characters like Kakashi make an appearance. Kakashi could be a bit jealous at first that Hiruzen is taking Naruto under his wing, but then he might see the benefits and offer his own advice to Naruto on the side.
Obviously Naruto would be one of the main characters as the title implies he is being trained. And then, the RWBY characters like Ruby, Weiss, Blake and Yang would also be main characters since they are the ones doing the training.
One possible plot could be that Naruto learns new jutsu from Asuma. Asuma might teach Naruto his unique wind - style jutsu, which could enhance Naruto's combat abilities. Naruto could also learn about leadership and strategy from Asuma, as Asuma was a respected leader in the Hidden Leaf. This training could make Naruto a more well - rounded shinobi.
In this fanfiction, perhaps Naruto could learn some unique jutsu from Asuma. Asuma was known for his wind - style jutsu, so he might teach Naruto advanced wind - style techniques that Naruto could incorporate into his Rasengan, creating a more powerful attack.
Obviously, Naruto and Tenzo would be the main characters. Naruto, as the one being trained, is the protagonist of the Naruto series. And Tenzo, with his unique skills, is the trainer in this fanfic.
Obviously Naruto would be one of the main characters as the title implies he is the one being trained. King Kai would also be a major character as he is the trainer. There might also be some cameos or interactions with Dragon Ball Z characters like Goku or Vegeta, since the fanfiction combines the two universes.
Obviously, Naruto and Deadpool would be the main characters. Naruto is the one being trained and evolving into a 'godlike' state. Deadpool is the trainer who brings his own set of skills and personality to the story.
The main characters would surely be Anakin Skywalker and Count Dooku. Anakin is the protagonist in a sense as we would see his development through Dooku's training. Dooku, on the other hand, is the one who imparts his knowledge and skills, and his character would also be explored in terms of his motives for training Anakin.
Obviously, Anakin Skywalker and Revan. Anakin is the one being trained, so he will be a central figure. His growth and development under Revan's tutelage will be a major focus.
Obviously, Harry and Merlin are the main characters. Harry is the one being trained, and Merlin is the trainer.
