I've never heard of a novel where Ultraman transmigrated to Naruto, but this kind of novel is generally more fictional. It might be adapted from comics, animations, or other forms of fictional works. If you want to read this kind of novel, you should go to some well-known online novel platforms to search for works that you might like.
I recommend the book "Ultraman: Tiga Descends the Heavens" to you. After the protagonist, Yu Zhou, rejected the mysterious little girl's mission, he was forcefully taken away from his small rented house and came to the world of Tiga Ultraman. He shuttled through different Ultraman worlds and fought side by side with various Ultramen. I hope you like this fairy's recommendation. Muah ~π
I recommend "Country of Light: Inheriting the Milky Way Empire at the Beginning" and "I Am in Diga, I Become Light at the Beginning" to you! They were all stories about transmigrating to the Ultraman world. I hope you like this fairy's recommendation. Muah ~π
πI recommend the following two novels to you: 1. "I Might Be a Fake Ultraman": The protagonist, Ultraman, picked up the system, transmigrated to another world, and cultivated PokΓ©mon. Although there was no female lead, there was a storyline where the main character pursued power, and there were also elements of Ultraman. 2. "Gaia's Transformation": The main character, Zhuo Lengxi, became a girl and traveled through various Ultraman space-time and real-life space-time. There were also elements of Ultraman in the dream.

Sorry, as a fan of web novels, my knowledge is limited to the data set I trained, and I can't provide a novel that transmigrated to Naruto and became Naruto or Sasuke. However, I can recommend some similar novels such as Naruto: I am Naruto and Naruto: I am Sasuke. These novels tell the story of the protagonist who transmigrated to the Naruto world to become Naruto or Sasuke and began an unusual adventure.
For novels that transmigrated to Naruto World to become Naruto or Sasuke, you can refer to the following examples: " Naruto: The Legend of the Nine Tails ": The protagonist is a young man named Li Ming who accidentally transmigrated to the world of Naruto and became the young nine-tailed fox Naruto. In this world, he began to fight against various enemies and gradually grew into a powerful ninja. 2 Naruto Eternity: The protagonist is a young man named Zhang Chen who accidentally transmigrated to the world of Naruto and became the young Uchiha. In this world, he experienced difficult battles with his companions and gradually understood the forbidden technique of the Uchiha clan-Infinite Moon Reading.
One interesting crossover could be Naruto obtaining Ultraman's powers. Imagine him using the Spiral Zankai Beam instead of the Rasengan. It would be a powerful and unique addition to his fighting style.
There were some novels where the main character transmigrated into the Naruto world, such as Naruto: The Strongest Ninja, Naruto Blade, and so on. The protagonists of these novels had all transmigrated to the Naruto world and displayed their abilities in this world.
Often, they start off as strangers. Ultraman characters might be confused by the ninja world's rules and customs, while Naruto characters are in awe of Ultraman's powers. For example, Naruto might be excited to learn about Ultraman's beam attacks and try to incorporate the concept into his own jutsu training.
Let me recommend you a few novels that transmigrated into Ultraman: 1. Dragon Ball Extreme Latitude-The protagonist Lin Duxiao transmigrated to Planet Vegeta and became a Saiyan. Through hard work, he became the strongest in all dimensions. 2. "I'm in Otto, and the instructor is Taylor!" - The main character, Lin Feng, traveled to Ultraman's time and space and became an Ultraman. His instructor turned out to be Taylor. 3. The protagonist, Ye Feifan, transmigrated to the Country of Light and took down Regent Ultraman at the beginning of the game, becoming a human Ultraman. 4. "I hid my Ultraman identity in the Armored Warrior World"-The protagonist, Xiao Ming, fell into a pit while fighting monsters. He transmigrated to the Armored Warrior World and hid his Ultraman identity. The above is my personal recommendation. Please feel free to tell me which one you like. I hope you like my recommendation. Muah ~π
