Well, a Lucario - girl would be a great addition. Lucario is known for its strong fighting and sensing abilities, so the Lucario - girl could be very perceptive and a great fighter. There might also be a Gardevoir - girl. Gardevoir is very elegant and has strong psychic powers. She could help Naruto understand the psychic aspects of the Pokegirl world and be a valuable ally in battles and in deciphering the mysteries of this new adventure.
Well, it could be about Naruto finding himself in a world full of Pokegirls. Maybe he teams up with some Pokegirls and goes on a journey to stop an evil force that threatens both the Naruto universe and the Pokegirl world. He could use his ninja skills along with the powers of the Pokegirls to fight battles.
It's likely a crossover fan fiction that combines elements of the Naruto universe with the concept of Pokegirls, creating a unique and imaginative adventure.
Sasuke could be one of the main characters. He might be initially skeptical or even hostile towards Naruto's mermaid side, but as the story unfolds, he could come to understand and support Naruto. Another character could be Sakura. She could use her medical ninjutsu skills to help Naruto if he gets injured during his underwater adventures.
Samul, of course, since he's Naruto's supposed father in this fanfic. He could be a powerful ninja who had some great influence in the past. Another character could be Naruto's mother, who might have a different story now considering her relationship with Samul. Also, characters like Jiraiya could still play an important role. He might be the one to guide Naruto in understanding his new identity as Samul's son and help him train to face the challenges that come with it.
Hinata is also a likely main character. In the original story, Hinata has a crush on Naruto. With Naruto being a smooth operator, he might notice Hinata's feelings more easily and their relationship could develop in a more romantic and interesting way. Kakashi could also be involved. Naruto could use his smoothness to learn new jutsu from Kakashi more effectively or to get Kakashi to trust him with more important missions.
The street kids themselves would be main characters. They could be a diverse group with different personalities and backstories. There might also be Naruto's friends like Sakura and Kakashi who could play important roles. Sakura could help with the kids' medical needs, and Kakashi could offer his wisdom in training the kids.
Sakura could be a main character. She might be the one who takes on a motherly role towards baby Naruto. She'd be very protective and try to teach him basic things. Kakashi could also be important. He'd use his wisdom to figure out how to deal with this situation and also keep an eye on Naruto's safety.
Sakura could be a main character. Since it's Naruto returning to Konoha, Sakura, being his friend and a strong ninja in her own right, might play a big role. Maybe she's the one who first welcomes Naruto back and they team up to face any threats.
Urahara Kisuke would be a great addition. His mysterious nature and vast knowledge could either help or hinder Naruto. Yoruichi could also be a main character. Her cat - like abilities and combat skills would make for some exciting interactions with Naruto. She could teach Naruto some new moves or they could team up against a common enemy.
Sasuke could be one of the main characters. At first, he might be among those who doubted Naruto, but as Naruto starts to prove everyone wrong, Sasuke has to re - evaluate his views. This could lead to some interesting character development for Sasuke as he sees Naruto's growth and realizes his own misjudgment.
