A group of thieves could also be included. They might initially try to steal from the Prince of Darkness but end up getting caught in his web of power and secrets. Their street - smart skills and lack of scruples could create some interesting dynamics as they interact with the Prince and other more noble characters.
A young, aspiring hero who is determined to defeat the Lord of Darkness. This hero could have some special powers or skills that make him a worthy adversary.
Many of the powerful noble houses would be his enemies. For example, the Lannisters, who are already in a struggle for power. They would not want to share or lose their power to the Prince of Darkness. And the Tyrells, who are also politically astute and would view the Prince as a threat to their influence and the stability of the Seven Kingdoms.
A young, inexperienced mage could be a main character. They might be just starting to learn about their powers when the rise of darkness begins. Their naivete could be both a strength and a weakness as they navigate this new, dangerous world. Another could be an old, grizzled warrior who has seen many battles but is now facing an enemy like never before in the form of the rising darkness.
A wise old mentor figure could be interesting. This character could be human and have a lot of knowledge about the world that they can pass on to the non - human protagonist. For example, a retired professor who has studied anthropology and can help the non - human understand human cultures.
A powerful Raikage - like character as an OC would be great. This character could be extremely strong in physical combat and have a no - nonsense attitude towards protecting Kumogakure.
The nosy neighbor can be an interesting addition. They might have their own opinions on whether the couple should love their home or list it. Maybe they're jealous and want the couple to move, or they could be overly attached to the neighborhood and try to convince them to stay.
Well, if it's a crossover with Ultraman, Ultraman could be a great addition. His super strength and light - based powers would contrast well with the Jetman's abilities. They could have a friendly rivalry at first but then team up to face a powerful kaiju that is threatening both their worlds.
Definitely Obito. Since they have a long - standing connection, it would be interesting to see how their relationship played out during Kakashi's Anbu days. Maybe Obito was still alive and had his own secret missions within the Anbu that intersected with Kakashi's.
There could be a powerful wizard from a far - off land. This wizard has knowledge of ancient magic that could help or hinder the Son of Neptune. Also, a group of dwarven - like creatures who are excellent craftsmen. They could create special weapons or tools for the Son of Neptune's journey. Additionally, an exiled god who sees the Son of Neptune as a means to regain his former glory.
A young and brave adventurer could be a main character. They are eager to explore the unknown and end up in the middle of the darkness. Their courage and determination to find a way out would drive the story. Another could be a wise old wizard who has some knowledge about the darkness but needs the help of others to fully escape it.
