They could use teamwork. Naruto with his powerful jutsu like the Rasengan, and Sasuke with his Sharingan and Chidori could combine their attacks. Their other friends can also support them. For example, Rock Lee could use his taijutsu to distract Frieza while Naruto and Sasuke prepare a big attack.
Well, Naruto would probably be shocked at first. He's used to his own world's threats. But being Naruto, he'd quickly jump into action. His friends like Sasuke would likely back him up. Naruto might try to talk to Frieza at first, seeing if there's a peaceful way to deal with him. But if Frieza attacks, Naruto would use his Rasengan. Sasuke could use his Chidori. And together, with their friends' help, they'd put up a good fight against Frieza's powerful attacks.
In this fanfiction scenario, Naruto and his friends would likely be extremely confused by Cell. Naruto might immediately jump into action, ready to fight. His friends, like Sasuke, would probably assess the situation carefully. Maybe Sakura would be a bit scared at first but then gather her courage. They would have to quickly figure out Cell's abilities, which are very different from the foes they usually face in their own ninja world.
If Naruto and Frieza were to encounter each other, in Naruto's universe, it would introduce a whole new level of threat that the ninja world has never seen before. The existing power structures would be shaken. Ninja villages might have to set aside their differences and unite against Frieza. In Frieza's universe, the discovery of a world full of people with unique powers like chakra could change his perspective on conquest. He might see the ninja as valuable assets or new challenges to overcome.
If Naruto and his friends meet Cell, Naruto would probably be the first to react. He'd shout some inspiring words and charge forward. His friends, depending on their personalities, would have different responses. Shikamaru might be thinking about strategies right away, while Choji would be ready to use his size and strength. Ino could try to use her mind - transfer jutsu, but it might not work on Cell due to his different physiology. They would all have to adapt quickly to deal with this new and unexpected threat.
Another concept could be a fusion of their powers. Imagine if Naruto was somehow able to absorb Frieza's power or vice versa. This could create a new and extremely powerful being. The story could explore how this new entity would interact with the two different universes. Would it be a force for good or would the power corrupt it? There could be a lot of internal conflict as the combined Naruto - Frieza entity struggles with its new identity and purpose.
One possible reason could be that Naruto is afraid of endangering his friends. He has many powerful enemies, and he might think that by staying away from his friends, they won't be targeted. For example, Orochimaru was always after Sasuke, and Naruto might fear that his closeness to Sasuke could put Sasuke in more danger.
In some fanfictions, the connection between Naruto and the Frieza race could be through a crossover of universes. Maybe a magic or some sort of interdimensional rift brings them together. For example, a powerful villain might use a forbidden jutsu in the Naruto world that accidentally opens a portal to the Dragon Ball universe where the Frieza race exists. This could lead to all kinds of interesting interactions, like Naruto trying to understand the Frieza race's power structure and them being equally intrigued by Naruto's chakra abilities.
It's not a mainstream or highly popular genre in the overall fanfiction community. Naruto and Frieza are from two completely different fictional universes, namely Naruto's ninja - filled world and Dragon Ball's action - packed universe. So combining them in such a way is rather out - of - the - box and might only appeal to a very niche group of fans who enjoy crossovers and unique, non - canonical interpretations.
One common theme is the clash of cultures. Naruto's world is all about ninja clans, chakra, and honor. Frieza's world in Dragon Ball is about power, conquest, and survival of the fittest. When Fem Frieza enters the Naruto universe, there's a huge culture shock for both her and the Naruto characters.
