Who are the potential new characters in 'Luffy raised by Dragon fanfiction'?

There could be a Suna ninja who becomes Naruto's mentor. This ninja might have a special skill in using sand and wind chakra together and teaches Naruto how to control his own chakra better in the Suna environment. Another potential character could be a young Suna girl who befriends Naruto and shows him the ropes of living in Suna, like where to find the best oasis for water.

Perhaps a wise old hermit. This character could live on an island that Luffy lands on during the time skip. The hermit has knowledge of the Void Century and can give Luffy some crucial hints about the true nature of the One Piece and the history of the world. His wisdom could also help Luffy grow as a leader.

There could be new human characters as well. Maybe some mages from other guilds who are curious about Natsu's new status. They could either be allies or potential threats. And don't forget about the celestial spirits. Since Lucy is Natsu's friend, the celestial spirits might get involved in some way. They could offer their unique powers or knowledge to help Natsu in his new role as the dragon king.

One potential character could be an old friend of Luffy's mother from her celestial dragon days. This friend might have different views now and could either help or hinder Luffy depending on their own motives. Another could be a servant who knew about Luffy's mother's secrets and has been waiting for the right time to reveal them to Luffy.

One potential new ally could be a powerful pirate from the past. For instance, a pirate who was known for his great navigation skills. Luffy could use his help to explore uncharted seas more easily.

One potential new member could be a skilled archer from a forest - dwelling tribe. They have amazing accuracy and can use special arrows made from rare materials found only in their forest. Another could be a mermaid or merman with the ability to control water in unique ways, not just for combat but also for things like navigation and finding hidden treasures.

A possible new character could be an oracle - like figure who is not from the traditional Delphi but is a seer on Olympus. This character could give Percy cryptic prophecies that are related to the future of Olympus and the demigod world. There might also be a group of centaurs who are specifically trained to protect Percy and serve as his advisors, different from the ones at Camp Half - Blood.

The Yonko would definitely be major antagonists. Since Luffy is in the New World, the likes of Kaido or Big Mom would be natural choices. Their vast power and influence would pose a great threat to Luffy and his crew.

Obviously, Harry Potter himself. Then there could be a Texan version of Hagrid, like a big - hearted rancher who discovers Harry's magical abilities. There might also be a local witch or wizard who acts as a mentor, someone with a thick Texan accent. And don't forget about the muggles in Texas, Harry's classmates at a regular school before he goes to Hogwarts. They could be curious, tough - as - nails Texans who don't quite understand Harry's strange behavior at times.

Obviously, Harry himself. Then there could be German - born wizards and witches who become his friends or mentors. There might be a strict German potions master like Snape in Hogwarts. And perhaps a German - version of Dumbledore, an old and wise wizard who guides Harry.
