For a 'War of Kingdoms fanfic', an exiled knight could be a great character. This knight was wrongly accused of a crime in their home kingdom and now wanders the lands, getting involved in the war in unexpected ways. Another interesting character could be a bard who travels from kingdom to kingdom, singing songs that either inspire or demoralize the troops. And a female assassin trained in the arts of stealth and death, who is hired by one of the kingdoms to take out key enemies. These characters would bring different perspectives and skills to the story, and their personal stories and goals would intertwine with the overall plot of the War of Kingdoms.
You could include the Gym Leaders from Pokemon Ruby. They have distinct personalities and battle styles. For example, Wallace, the Sootopolis City Gym Leader. His elegance and powerful Water - type Pokemon make him a great character. Another interesting character could be Steven Stone. He's a strong trainer and a bit of a mystery. And of course, the Team Magma or Team Aqua grunts. They add an element of conflict to the story.
Well, often the fearless warrior types are popular. Characters like Sir Aldric, a knight known for his unwavering loyalty and incredible combat skills. He's always in the thick of battle, defending his kingdom.
Owen Grady would be an obvious and interesting choice. His skills with dinosaurs and his connection to Blue could be further explored. For example, he could be on a mission to rescue Blue from a new threat in the post - Dominion world.
You could include Winter Schnee. Her strict military upbringing and her relationship with Weiss can be a source of conflict and growth. Additionally, Mercury Black, with his acrobatic fighting skills and his loyalty to Cinder, can be used to show the darker side of the RWBY world and add some intense fight scenes to the fanfic.
In a crossover with 'Naruto', Naruto himself would be an interesting addition. His love for ramen could be a starting point. He could be amazed by Soma's cooking skills and end up challenging him to a friendly shokugeki. Another character could be Kakashi. His laid - back attitude yet sharp taste buds could add an interesting dynamic. He could be a tough judge in a shokugeki battle.
Zero would be an obvious and interesting character to include. His backstory and his relationship with X could add depth to the fanfic. Also, in a crossover, he could have some unique interactions with characters from other franchises.
One idea could be a story about an underdog kingdom rising to power through unexpected alliances. Maybe a small, resource - poor kingdom teams up with a group of powerful but outcast mages. Another could be a love story between a warrior from one warring kingdom and a noble from an enemy kingdom, which could potentially change the course of the war.
One idea could be a story about an underdog kingdom that discovers a long - forgotten magic and uses it to turn the tides of the war. Another could be a fanfic centered around the love story between a knight from one kingdom and a princess from an enemy kingdom, which then affects the course of the war. Or perhaps a tale of a young strategist who rises through the ranks and devises brilliant battle plans for his kingdom in the War of Kingdoms.
One interesting character to include would be Punisher. His extreme methods and lack of regard for the law would be a great foil to Daredevil's more law - abiding nature. Spider - Man is also a good choice. His youth and naivete, along with his sense of responsibility, would create some interesting dynamics. And don't forget about Luke Cage. His strength and his loyalty to his community could be a great asset in the story. He could side with Daredevil or be caught in the middle of the conflict between different factions.
Temari would be a great addition. She's strong - willed and a skilled shinobi. The OC could have some friendly rivalries or training sessions with her. Also, Baki, as a sensei in Suna, could play a role in mentoring the OC in some Suna - specific jutsu or combat styles. Another interesting character could be the Fourth Kazekage. Even if it's just through flashbacks, his actions and decisions had a huge impact on Suna, and the OC could learn about Suna's history through stories about him.
