A historian could also make an interesting main character. They could have in - depth knowledge of different forms of governance and use that to help build better kingdoms in the Tensura world. They might also know about ancient battles and strategies that could be applied in the new world.
A young gamer could be a great main character. They would already be familiar with concepts like leveling up and finding rare items. In the Tensura world, they could use this knowledge to their advantage, quickly becoming a powerful force. They might also be more open to befriending the diverse creatures in the world due to their experience with different game characters.
A self - sacrificing hero type from another fictional world could be a good main character. For example, someone like Harry Potter reincarnated as a character in Naruto. He would bring his sense of justice and his unique magical skills (adapted to chakra - based skills in the Naruto world) and could have a great impact. Another option could be a character from a post - apocalyptic world who is used to fighting for survival. They would have a different perspective on the ninja battles and might introduce some new combat strategies.
Perhaps the reincarnated character has a special ability that allows them to communicate with the unique monsters in the Tensura world. This ability could lead to forming alliances that no one else could, and they could use these to their advantage to gain power and protect the world from new threats.
He could be reincarnated as one of the Uchiha clan members. This would be really interesting as he would have to deal with the Sharingan and the Uchiha's history. He might even change the fate of the clan.
The main character is Rimuru Tempest. He is a slime who has unique powers and a great deal of charisma. Another important character is Veldora, the storm dragon who befriends Rimuru. There is also Shizu, a human who has an impact on Rimuru's early development. And then there are characters like Benimaru, a powerful ogre who becomes one of Rimuru's loyal followers.
It could be an ordinary person from our world, like a high - school student. They would bring their own set of values and knowledge from the real world into the pokemon world. This contrast between the two worlds could create a lot of interesting storylines.
It could be an old enemy from Percy's past life who has also found a way to be reincarnated. This enemy might hold a grudge against Percy for something that happened in their previous encounter and is now seeking revenge in this new life.
Perhaps there is a dark force that is awakened by the oc's reincarnation. This force might have been dormant for a long time, and the oc's new life energy or something about their reincarnation stirs it. It could be a force that wants to destroy the balance of the pjs world, and the oc is the only one who can stop it because of their unique perspective from their past life.
In the Tensura web novel, Rimuru Tempest is the central figure. He is a slime with unique abilities. Shuna is another important character. She is often involved in the management of Rimuru's nation. Diablo, a powerful demon, is also a main character. He serves Rimuru and is extremely powerful in combat. These characters, along with many others, contribute to the development of the story, with their different personalities, abilities, and goals.
It could be an ordinary person, like a modern - day office worker who gets reincarnated. Not the typical hero or chosen one.
I think Daenerys Targaryen would be really interesting. If she were reincarnated, she could use her past experiences to be an even more powerful and just ruler. She already had a complex journey in the original series, and reincarnation would add more depth to her character. She might be able to avoid some of the mistakes she made in her first life, like trusting the wrong people.
