Definitely, Gaara could be a central character. His control over sand could be the basis for some really cool transformations. Maybe he could transform into a giant sand creature or something more refined like a sand - armor form. Kiba with Akamaru could also be a main character. They could have a combined transformation where they become a more powerful and fearsome beast - like form. And Tenten could be a main character with a transformation related to her weapon - using abilities, perhaps a transformation that gives her an unlimited supply of weapons.
Obviously Naruto himself would be a central figure. He could be the enthusiastic player who always tries to bluff his way through the game. Sasuke might also be there, being the more reserved and calculating player. Sakura could be the one who scolds them both for their reckless betting. Kakashi could be the experienced player who gives out tips and tricks now and then.
Naruto would obviously be one of the main characters. He'd bring his ninja skills and his never - give - up attitude. From Game of Thrones, Daenerys could be a key character in the harem. She's a strong and powerful woman, and her meeting with Naruto could lead to an interesting dynamic. Also, Sansa Stark could be part of it, as she has her own political acumen and could interact with Naruto in unique ways.
In 'the dating game naruto fanfiction', Naruto is surely a main character. He's the protagonist of the original Naruto series and his outgoing and friendly nature would make him a key player in the dating game. Hinata is another main character. Her shy but determined personality when it comes to Naruto makes her an interesting part of the story. And of course, Kakashi, as Naruto's mentor, could also be involved in some way, perhaps giving dating advice or setting up some of the dates.
The geese themselves would be obvious main characters. Each goose could have different traits, like one being the brave leader, another being the cautious one.
Naruto himself could be the main character. Since he's the protagonist of the original series, it would be natural to have him as the center of the fanfiction. He could be drawn into the new game world and have to use his unique skills and determination to succeed.
Madara Uchiha could be a great antagonist in this kind of fanfiction. He has the power and the ambition. He could manipulate the war game from behind the scenes, perhaps using his Sharingan to control the minds of some of the participants. He wants to reshape the ninja world according to his own vision, and the war game provides him with an opportunity to do so without directly confronting all the ninja forces at once.
Naruto could also be a main character, even if he's not a medical expert. He could be visiting his injured friends in the hospital and accidentally stumble upon a conspiracy. His determination and never - give - up attitude would be useful in uncovering the truth.
Definitely Naruto himself. He's the main character of the Naruto series, so he has to be there. In a crossover with Attack on Titan, he could meet Eren. Naruto's determination and Eren's drive to protect his people could make for an interesting dynamic between them.
Naruto's children would likely be main characters. They would inherit his strength and determination. Also, the students of the new generation of ninja academies could play important roles as they strive to make their mark in a world shaped by Naruto and his peers.
Naruto for sure. He'd be the star attraction with his wild and unpredictable ninja skills. Hinata could be another main character. She might be shy at first but then shine in acts that require grace and concentration. Shikamaru could be in charge of the strategic planning for the circus, like how to set up the tents and manage the shows efficiently. And Kiba with Akamaru could have an animal - based act that wows the audience.
