Well, in Naruto fanfiction, Kabuto could offer his knowledge of forbidden jutsu to Naruto's side. This knowledge might be crucial in dealing with a super - powerful enemy that the regular ninja techniques can't handle. He could also use his shape - shifting abilities for espionage. He could transform into an enemy spy within their ranks and gather intel. This would give Naruto and his comrades a better understanding of the enemy's movements and intentions, which is really helpful in a fictional story.
In some fanfictions, Naruto might use his new jutsu that he's developed through intense training. He could overpower Kabuto with his Rasengan variations, like the Big Ball Rasengan, and rescue Tsunade while Kabuto is distracted by the powerful attack.
In the 'kabuto sad story', Kabuto could be anyone really. He could be a character from a small - town folktale, where he was known for his kindness but was wronged by the people in the town. Maybe he was framed for a crime he didn't commit, and as a result, he lost his reputation and had to live in isolation. This would be a very sad situation for him indeed.
To develop Fem Kabuto's character, give her a personal goal that is separate from Orochimaru's. In the fanfiction, she might strive to find a cure for a certain ninja - world disease using her medical knowledge. This not only shows her as more than just a sidekick to Orochimaru but also gives her a positive and independent identity. As she pursues this goal, she can grow and change, and her interactions with Naruto can be shaped by this new - found purpose.
Well, Geralt might die as a result of a powerful curse or magic. Maybe he angered a powerful sorcerer or witch who cast a spell on him that he couldn't resist. This could be a slow and agonizing death as the magic takes its toll on his body and mind.
