Well, one way could be in their physical abilities. Maybe in the fanfic, Naruto is shown to have some of Zetsu's stealthy movement skills, like being able to blend into the environment in a similar way. Another similarity could be in their connection to nature. Zetsu has a strong link to the plant - like aspects of nature, and Naruto's chakra might be shown to have a similar kind of connection in the fanfic.
At first, Naruto would likely be extremely shocked. He has always considered Sakura a friend and teammate, so this would be a huge blow. He might question his own judgment in trusting her.
Here are some recommended novels that betray the male protagonist:
1. " Husband Lives in the Dantian ": The female protagonist was betrayed by her ex-boyfriend, and then she counterattacked with the help of her cheap husband's property and cheat.
2. " Female Supporting Actor's Counterattack: Male Lead, Stop and Don't Move ": The female protagonist completed the system's mission and became the villain female supporting actor.
3. " The Vicious Female Lead and Her Executioners ": The female lead made a deal to smear the original female lead and make the original female lead a bad person so that the male lead could choose her.
These novels all contain plots that betray the male protagonist. I hope you will like one of them.
There are a few novels that I can recommend to you. They tell the story of the ex-boyfriend betraying the female protagonist and the CEO. These novels included " The CEO's Good Plan for Unending Love "," The Ex-Wife's Counterattack, The CEO Is Too Difficult to Flirt With "," The Cute Wife of Weiai: The Black-bellied CEO Is Not to Be Trifled With "," Mr. Liang Dotes His Wife Too Much ", and " The Prosperous Life Is Only for You ". The plots of these novels were compact and full of elements of reversal, revenge, and sweet love. The female protagonist retaliated and counterattacked after being betrayed, while the male protagonist was a black-bellied CEO who gently doted on the female protagonist in marriage. I hope you like these novels!
I'm not sure specifically as there could be many different interpretations in fanfiction. But it might involve Zetsu using his unique abilities to rescue Naruto from a dangerous situation, like a powerful enemy attack or a life - threatening trap.
A third theme could be growth. They both start from certain points in their characters and develop over the course of the fanfic. Tobi might become more serious or Zetsu might open up more, depending on the plot and how the author wants to develop their relationship.
One main theme is loyalty. Given their relationship in the Naruto series, fanfictions often explore how loyal they are to each other and their common goals.
In a fanfic where Naruto is trained by Zetsu, the story could take an interesting turn. Zetsu has knowledge of the Akatsuki and their secrets. Naruto could learn about the organization from the inside out. This knowledge could help him in his quest to bring peace. He might also gain some physical enhancements. Zetsu is quite durable in his own way, and Naruto could inherit some of that sturdiness. This would make him an even more formidable opponent in battles against strong foes like Pain or Madara.
