The main characters would be Naruto and Akamaru. But there could also be other characters involved like Kiba, Akamaru's owner. Kiba might be worried about Akamaru and work together with Naruto to figure out what's wrong and how to fix it. Also, characters like Shino or Hinata could make an appearance, maybe they offer some help or just witness the events that unfold.
In this fanfiction, perhaps Akamaru's 'in heat' state causes some chaos in the village. Naruto then uses his ninja skills to keep Akamaru in check and prevent him from causing too much trouble. He might also seek advice from Kakashi or other experienced ninjas on how to deal with it.
Obviously, Harry himself would be the main character. His friends like Ron and Hermione are also likely to be involved. They would probably try to support Harry or figure out what's going on with him.
The main characters are Naruto and Tsume. Naruto is a well - known character from the Naruto series. He is a young ninja with a lot of energy, a big heart, and dreams of becoming the Hokage. Tsume, on the other hand, is a tough and experienced ninja. She is often associated with her clan's characteristics, which might include loyalty and a certain fierceness. In this fanfiction, their interactions and how they deal with the situations they are in would be the focus.
The main characters are obviously Kakashi and Naruto. Kakashi is the experienced and cool - headed ninja, while Naruto is the energetic and determined protagonist.
It's hard to say for sure without reading the specific fanfiction, but it could be Naruto himself. He's often at the center of many fanfictions. Maybe he discovers this invisible heat ability and has to learn to control it.
The main characters are Naruto and Kiba. Naruto is the energetic and determined ninja who has a strong will to become Hokage. Kiba, on the other hand, is a skilled ninja with his trusty companion Akamaru. He is known for his wild and somewhat brash nature.
The main characters are Naruto and Hana. Naruto is a well - known character from the Naruto series, a very energetic and determined ninja. Hana, on the other hand, is also a ninja with her own set of skills. In this fanfiction, they are likely to be the central focus, with their actions and interactions driving the story forward.
Simon, if he makes an appearance in the fanfiction, would have a very different dynamic with Marceline. He has a long history with her and his wisdom could play a crucial role in helping her understand and manage her 'vampire in heat' situation. His presence could also bring up a lot of memories for Marceline, which would add depth to the story.
There could also be new characters introduced. Maybe a business rival who is jealous of Naruto's success. This rival could be from another village or even an outsider who has his own motives for trying to take down Naruto's billion - dollar empire. And of course, the Hokage would still play a role, as Naruto's actions as a billionaire would have an impact on the village's politics and power structure.
Definitely Naruto himself. He'd be a central character, causing chaos and bringing energy to the daycare. And Sasuke would also be there, probably being a bit of an aloof kid that Naruto is determined to get close to.
