Kim's sidekick, Rufus, and Naruto's summon, Gamakichi, could have a really fun interaction. Rufus's small size and cute appearance but useful skills could be an interesting contrast to Gamakichi's larger - than - life frog - like presence. They could both provide some comical relief during the more intense parts of the fanfiction.
Ron and Shikamaru could have some great interactions. Ron's laid - back but sometimes surprisingly insightful nature could play off well against Shikamaru's intelligent and lazy - seeming demeanor. They might start off not understanding each other but end up becoming good friends as they face challenges together.
Kim Possible would also be a great character in this crossover. Her ability to handle various situations and her quick thinking would be valuable in the Naruto universe. She might be able to come up with unique strategies to deal with the ninja villains, using her own set of skills and gadgets.
The interaction between Naruto and Mine would be really interesting. Naruto's positive and determined attitude would contrast with Mine's more serious and sometimes cynical nature. They could have some great conversations where Naruto tries to cheer Mine up or convince her of the power of hope.
I think Naruto and Reverse Flash would be an intense interaction. Reverse Flash's evil and calculating nature would be a huge contrast to Naruto's good - heartedness. Naruto would be determined to stop Reverse Flash's evil plans, and Reverse Flash would likely underestimate Naruto at first. Another interesting interaction could be between Sasuke and the Flash. Sasuke's brooding and powerful presence would clash and also complement the Flash's more positive and speedy demeanor.
Sasuke and Livewire could also have an interesting dynamic. Sasuke's cool and brooding nature might initially make Livewire a bit wary of him. But as they work together, perhaps Sasuke could show her some of his Sharingan abilities, and she could show him how her technology works. It could lead to some really cool team - up moments in battle.
The interaction between Naruto and Power Girl would be the most interesting. Naruto, with his exuberant and talkative nature, would constantly be asking Power Girl about her powers. Power Girl, on the other hand, would be both amused and a bit exasperated by Naruto's naivete and energy. Their conversations would be a blend of Naruto's ninja - themed talk and Power Girl's superhero - centric ideas.
Definitely Naruto and Iron Man. Naruto's more carefree and instinct - based nature would contrast with Iron Man's calculated and high - tech approach. They could learn a lot from each other, like Naruto learning about advanced technology and Iron Man getting inspired by Naruto's willpower.
I think Naruto and Maz Kanata would be really interesting. Maz is this wise old being who has seen a lot. Naruto could learn a great deal from her about the ways of the Star Wars universe, and in return, he could show her some of his ninja techniques. They could exchange stories about their different worlds and the powers that exist within them.
Definitely Naruto and Issei. Issei is all about perverted thoughts and power - seeking, while Naruto is more about friendship and protecting his comrades. Their interactions would be full of contrasts and they could learn a lot from each other.
Definitely Naruto and Moka. Naruto's energetic and positive nature would contrast with Moka's more reserved and sometimes vampiric aloofness. Their conversations could be really fun to read. Naruto would probably be curious about Moka's fangs and her vampire powers, while Moka might be intrigued by Naruto's ninjutsu.
Definitely Naruto and Beast Boy. Imagine Naruto being amazed by Beast Boy's ability to transform into different animals and Beast Boy being curious about Naruto's ninja skills. They could have some really fun exchanges, like trying to outdo each other in terms of speed or stealth.
