His intelligence and strategic thinking could be a great asset in the story.
One popular theme could be adventure. In Naruto fanfictions, characters often embark on exciting quests, and with Kubichiriboucho and Yugao involved, it could be about exploring new areas in the Naruto world. Another theme might be friendship. Since the Naruto series highly values friendship, a fanfiction could focus on how Kubichiriboucho and Yugao form or strengthen their friendship. Love is also a common theme. There could be a romantic storyline between them or how their relationships with other characters are affected by love.
The outcast warlord is always an interesting character. Shunned by the other warlords, he has to rely on his own wits and the loyalty of a few followers. He could be hiding some amazing abilities or a great secret. Then there's the warlord who is a master of disguise. He can infiltrate enemy camps easily and gather crucial information. This makes him a key player in the power struggles. Also, the warlord with a split personality. One side of him is kind and just, while the other is ruthless and power - hungry. This internal conflict adds depth to the character and the story.
Odd could be an intriguing supporting character. His humorous and sometimes rash nature can add a lot of spice to the fanfiction.

She might have her own sub - plots that interact with Jeremy and Aelita's story.
Some fanfictions might introduce a foreign ninja who has a strange connection to spiders, similar to the Aburame. This character could be from a far - off land and have a completely different understanding and use of spider - based powers. Their interactions with the Aburame clan, especially Shino, could be full of tension, curiosity, and the exchange of new ideas about spiders. They could be a potential ally or a new enemy, and exploring their motives and backstory can be really engaging in the context of the Naruto Aburame Spider Fanfiction.
A witch character with the power to create illusions that are even more powerful than those in the ninja world would be really fascinating. She could use these illusions to deceive Naruto's enemies or even to teach Naruto new ways of using illusions himself. Also, a witch who has a deep connection with nature and can use nature's magic in the middle of the ninja world's battles would be quite an interesting addition to the fanfiction.

There are often original characters in these fanfictions. One interesting type is the ancient chakra - being who guides Naruto on his path to becoming the God of Chakra.

Another could be a young ninja who is inspired by Naruto's journey and tries to follow in his footsteps, but has their own unique take on chakra manipulation. And sometimes, there are antagonists created specifically to oppose Naruto's new - found god - like status, like a dark chakra - user who wants to steal his power.
Some original characters are antagonists. They might be jealous of the main character's newfound elemental sage powers and try to steal them or use them for their own evil purposes. Their motives and actions can create a lot of tension and conflict in the story.
