Naruto is a great character to pair with Madara in fanfic. Their contrasting personalities and beliefs can create a lot of interesting storylines, as we've already discussed. Another good character could be Sasuke. Sasuke's own complex relationship with power and his Uchiha heritage could lead to some intense interactions with Madara.
Kakashi could also be an interesting character to pair with Madara in a fanfic. Kakashi is known for his intelligence and his Sharingan, which has a connection to the Uchiha clan. He could be in a situation where he has to outwit Madara or perhaps even understand his motives better than anyone else. It could be a story full of mind games.
Naruto himself would be a great character to pair with Raiden. Their different powers and personalities would create an interesting dynamic. Naruto's positive and determined attitude could complement Raiden's more stoic nature. Another good pairing could be with Kakashi. Kakashi's wisdom and combat experience could work well with Raiden's unique abilities. And Sakura could also be a good match. She could learn from Raiden's fighting style, and Raiden could be impressed by her medical ninjutsu skills.
Sakura could be a great character to pair with Mirror Naruto. Their dynamic could be really interesting, especially if Mirror Naruto has different personality traits. She might be attracted to his new - found qualities or be in conflict with him because of their differences. Another good option is Hinata. If Mirror Naruto has a different backstory, Hinata's shy but determined nature could interact in a unique way with him.
With Naruto, Sasuke could be paired in a fanfic. Their complex relationship can add a lot of depth to the story. For Hinata, Shino could be an interesting character to include. His bug - based jutsu and calm demeanor could contrast with Hinata's more emotional side. For Tenten, Neji (before his death) could be paired. They are both from the same team and Neji's Byakugan and combat skills could complement Tenten's weapon skills.
In a crossover with the Avengers, Thor would be an interesting character to pair with Madara. Thor has his godly powers and Mjolnir, while Madara has his Sharingan and immense combat skills. The clash between Thor's lightning and Madara's fire - based jutsu would be epic. Another good pairing could be with Batman. Batman's strategic mind against Madara's cunning and power would make for a great dynamic. Batman would have to rely on his gadgets and intelligence to outwit Madara.
Kiba could also be a good match. If Naruto's sister has an affinity for animals like he does, they could bond over their love for their respective animal companions. They could train together, and their combined skills with their animal partners could make them a formidable duo in battles and missions.
Yoshi would be an excellent character to pair with Bowuigi. Yoshi's friendly and helpful nature can contrast or complement Bowuigi's personalities. Donkey Kong is another good choice. His brute strength can be a great counterpoint to Bowuigi's more strategic thinking. And Toad could be added for his loyalty and sometimes comical nature.
A rogue could be a great character to pair with an artificer in fanfic. The rogue's stealth skills combined with the artificer's gadgets can lead to some really interesting heist - like scenarios. For example, the artificer could create a device that disables security systems while the rogue sneaks in to steal a valuable item.
Tanjiro would be a great character to pair with rengoku. Their different personalities could create an interesting interaction. Tanjiro's kind - hearted nature and rengoku's fiery determination could lead to some great storylines.
Hawks is a great character to pair with Dabi in fanfic. Their relationship in the original story is complex and full of tension, which can be explored further in fan - made stories. There's also Shigaraki. Since they are both important members of the League of Villains, there's a lot of potential for interesting dynamics between them in fanfics.
Naruto could be a great character to pair with Menma. Their personalities could create an interesting dynamic. Naruto's determination and Menma's more gentle nature could complement each other well in a story about friendship or even a budding romance.
