I'm not sure if it's popular. There are so many Naruto fanfics out there, and it's hard to tell which ones are really popular without doing some research. It could be that it has a small but dedicated following among fans who are interested in this particular scenario of Tsume being hypnotized by Naruto.
One common theme is the exploration of power dynamics. Hypnosis can be a tool to either gain power over others or lose one's own power. For example, a character being hypnotized might lose their ability to use ninjutsu, changing the balance of power in a fight.
One possible plot could be that an enemy uses a new jutsu to hypnotize Naruto and then makes him target Ino. Naruto, under the hypnosis, starts acting strangely towards Ino, which causes confusion among their friends. The story could then revolve around how their friends try to figure out what's wrong with Naruto and break the hypnosis before he does something really bad to Ino.
A rogue ninja from a neighboring village could be the villain. This ninja might have a vendetta against Ino's family and uses Naruto as a tool to get to her. He hypnotizes Naruto because he knows Naruto is strong and his actions while hypnotized would create a lot of trouble for Ino and Konoha.
One interesting 'Naruto hypnotized fanfic' could be about Naruto using his newfound hypnotic powers to make his friends see their dreams as if they were real. For example, he might hypnotize Sasuke to see a world where the Uchiha clan was never massacred. This would lead to a lot of self - discovery for Sasuke and a change in his relationship with Naruto.
One popular 'naruto characters hypnotized fanfic' could be 'Hypnotic Influence on Naruto'. In this type of fanfic, often the plot might involve a character using hypnotic powers in unique ways. For example, an antagonist could hypnotize Naruto to turn against his friends, creating a lot of drama and conflict within the story.
Well, it could be a really wild plot. Maybe Tsume is hypnotized by Naruto and starts to see things in a different way. It might involve some sort of adventure where Naruto's hypnotic influence leads Tsume to do things she normally wouldn't. However, this is all speculation as I haven't actually read the fanfic.
Another character that can be involved is Kakashi. He might be the one who discovers Naruto has been hypnotized and uses his wisdom and skills to try and reverse it. Also, characters like Sakura could play a role. She may be worried about Naruto and try to help in any way she can, like researching about the hypnosis or providing medical support if needed.
Well, 'hypnotized fanfic' could be about a story where a character is hypnotized. It might involve things like the character's altered state of mind, how they interact with others while hypnotized, and the consequences of being in that state. Maybe it's a part of a fantasy or science - fiction story within the fanfic world.
Well, without reading the specific 'cynthia hypnotized fanfic', it's hard to say exactly. It could be a story where Cynthia is put under hypnosis and then various fictional events unfold around that situation. Maybe it involves her experiencing different emotions, going on adventures in a trance - like state, or perhaps there are other characters who interact with her while she's hypnotized.
