There could be an original character who is an expert in clockwork technology. This character might serve as a guide or an ally to Naruto, helping him understand and use the clockwork - related things. They could also have their own backstory and motives related to the combination of the two worlds.
Sasuke could also be a main character. He might be initially skeptical or even opposed to the integration of clockwork elements into the ninja world. His relationship with Naruto in this new context, with the added complication of clockwork, could be a major focus of the story, like whether they can work together to face new threats brought about by the clockwork elements.
Maybe the main antagonist is an artificial intelligence on the Clockwork Planet that views Naruto and his chakra abilities as a threat to its control over the planet. It starts to send mechanical beasts to Naruto's world to capture him and study his powers. This AI is highly intelligent and has a vast network of clockwork devices at its disposal, making it a formidable foe for Naruto and his friends.
It could be that Naruto or one of his friends has some sort of encounter with the 'clockwork master'. So Naruto could be considered a main character in the sense that his actions and decisions are intertwined with the 'clockwork master'. For example, Naruto might seek the help of the 'clockwork master' to defeat a particularly difficult enemy who has an immunity to normal ninja attacks but could be vulnerable to the clockwork - based jutsu.
Typically, the main themes could include horror, the clash of different universes (Naruto's world and Clockwork's concept). There might be elements of the unknown and the disturbing, which are common in creepypasta. It could also explore how Naruto's characters react to the strange and often menacing presence of Clockwork or elements related to it.
Well, obviously Danny Phantom is one of the main characters. He's the one being raised by Clockwork. And of course, Clockwork himself is a major character. He's the one taking on the role of Danny's 'parent' or mentor in this fanfiction.
Since I haven't read it, I can't say for sure. It could be an original character created for this fanfiction related to the idea of clockwork and the concept of time running out. Or it might be characters from an existing series that the author has incorporated into this story with a new twist based on the 'time is up' theme.
Obviously, Danny Phantom is one of the main characters. He is the half - ghost hero who becomes Clockwork's apprentice. Clockwork himself is also a main character. He is an ancient and powerful ghost who has control over time. Then there could be Danny's friends like Sam and Tucker. They might play important roles in supporting Danny or getting involved in the time - related adventures that Danny embarks on as an apprentice.
Perhaps the story explores how the order and precision of clockwork mechanisms interact with the chaotic and often unpredictable nature of the Naruto universe. This could create some really cool plotlines, like a villain using clockwork - based jutsu to try and control the flow of battles in a very methodical way.
In some naruto x mito fanfiction, Kurama, the Nine - Tails, can also be a significant character. Since Mito was the first Jinchuriki of the Nine - Tails, Kurama's presence and his relationship with both Naruto and Mito can add depth to the story. For instance, Kurama might share some memories of Mito with Naruto, which could change Naruto's perspective on certain things.
In Naruto x Ryuzetsu fanfiction, the two main characters are Naruto and Ryuzetsu. Naruto, the protagonist of the Naruto series, is a powerful and kind - hearted ninja. He has a strong will and a desire to protect his friends and village. Ryuzetsu, on the other hand, is a character with her own charm. She may be from a different place than Naruto, perhaps a hidden village or clan. She has skills and abilities that make her an interesting counterpart to Naruto, and their interactions form the core of the fanfiction.
Obviously, Naruto is a central character. He's the energetic and determined ninja we all know. Suzumebachi, on the other hand, is also a main character in this fanfiction. Their interactions drive the plot forward. Naruto's quest for power and his sense of justice often clash or combine with Suzumebachi's own motives and abilities. Their relationship, whether it's a friendship or something more, is what the fanfiction often focuses on. We see how Naruto's ninja skills and Suzumebachi's unique traits play off each other as they face different situations in the story.
