Clay from 'Wings of Fire' would be a great character to include in crossovers. His kind and brave nature could make him a valuable ally in different universes. Also, Harry Potter could be included if it's a 'Wings of Fire' and 'Harry Potter' crossover. His magical skills and leadership could be interesting to combine with the dragon - related elements. And Anakin Skywalker from 'Star Wars' could be another popular choice. His fall to the dark side and then redemption could create a complex dynamic when interacting with the dragons.
Tsavorite from 'Wings of Fire' is a strong character that could be used in crossovers. In a crossover with 'Percy Jackson', she could use her combat skills and dragon abilities to fight alongside the demigods. Frodo Baggins from 'Lord of the Rings' could also be a great addition in a crossover with 'Wings of Fire'. His journey to destroy the One Ring could be intertwined with the dragons' quests. Additionally, Katniss Everdeen from 'The Hunger Games' could be an interesting character to include. Her survival skills and determination could be a contrast or complement to the dragons' powers in a crossover story.
For the Wings of Fire side, it could be Clay. His strong and kind - hearted nature would make him an interesting character to be thrust into the SAW world. He would try to protect the others and use his earth - related dragon abilities to his advantage. From the SAW side, maybe Jigsaw could be a main character. His complex and twisted motives would create a lot of tension when interacting with the Wings of Fire characters.
Ink!Sans is a popular pick. His creative and somewhat unpredictable nature can bring a lot of color (literally and figuratively) to a Glitchtale crossover. He could use his paint powers in the Glitchtale world in ways that no one expects. Also, Bete Noire from Glitchtale is a character that many fans like to include. Her relationship with other characters, especially her sister, can be explored in new and interesting ways when in a crossover situation.
The Nurse is also great for crossovers. Imagine her in a world like Final Fantasy. She could use her healing abilities to help the party members. And then there's the Goblin Tinkerer. If he was in a Portal crossover, he might be interested in the advanced technology there and try to tinker with it, creating some interesting and comical situations.
Definitely Yu Narukami. He's the main character in Persona 4 and his leadership and strong Persona abilities make him a great addition to crossovers. Yosuke Hanamura is also popular. His comical nature and loyalty can add some humor and heart to the story. Chie Satonaka is another one. Her martial arts skills and determination are great traits in crossovers.
One popular character to include is Batman from DC Comics. The contrast between Batman's detective skills and gadgets and Raiden's superhuman powers would be fascinating. Another is Goku from Dragon Ball. Goku's love for fighting and his ability to reach new levels of power could lead to some epic battles with Raiden. And of course, Samus Aran from Metroid. Samus' armored suit and her exploration of alien worlds could be combined with Raiden's adventures in a unique crossover story.
From the 'Twilight' side, Edward and Bella are very popular characters to include. Their complex relationship could add a lot of drama to the fanfiction, especially when combined with elements from the 'Fire' and 'Light' concepts. Maybe the fire light could have an impact on Edward's vampiric abilities or Bella's connection to the supernatural world.
One popular character might be a dragon with a unique color or pattern that stands out. For example, a dragon with iridescent scales that has some special power related to it. Another could be a character who is an outcast from their tribe but has a heart of gold. They often get into all sorts of adventures and make friends with other misfits.
Engineering characters from the Katana Fleet can also be great inclusions. They can use their technical knowledge to help or hinder the situations in the crossover. Maybe they have to fix a crucial piece of technology from the other series' world, or they might accidentally cause a problem while trying to adapt their own technology to the new environment.
The Emperor of the Rising Sun is a character full of potential in crossovers. In a crossover with the Star Wars universe, his unique leadership style and the advanced technology of his faction could create some really interesting storylines. He could be making deals with the Sith or trying to resist the Galactic Empire. And of course, Natasha Volkova, with her sniper skills, could be a valuable asset in a crossover, like in a battle against the Covenant in the Halo universe.
Cleopatra is another great character. Her beauty and intelligence made her a very influential figure. In a crossover, she could use her charm and wits to manipulate characters from different settings. Say, if it's a crossover with a superhero world, she might try to enlist the help of the superheroes for her own political gain.
