The protagonist of the main Megami Tensei games, like the Demi - Fiend from Shin Megami Tensei III, is also a great choice. His unique backstory and abilities can add depth to any crossover story. He can bring his demon - slaying skills and knowledge of the Megami Tensei world into a new setting.
The protagonist is often a popular choice. Since the player controls the protagonist in the game, there's a lot of room for interpretation in fanfiction. Writers can expand on the protagonist's backstory, their inner thoughts, and how they really feel about the various events in the game.
A third plot idea is a crossover with a magical girl anime like Sailor Moon. The magical girls and the Megami Tensei characters could find themselves in a situation where they need to combine their powers to defeat an evil force that is trying to merge their two very different worlds into one chaotic mess. The contrast between the cute, positive - energy magical girls and the often darker Megami Tensei characters would create a lot of interesting storylines.
Typically, there is a protagonist who is often an ordinary person thrust into extraordinary circumstances related to the demon world. There might also be various supporting characters like mentors who guide the protagonist in understanding the rules of the demon summoning and the power they possess.
A cool 'Shin Megami Tensei Nocturne Crossover Fanfiction' idea could involve a crossover with the Devil May Cry series. The stylish combat and demon - slaying nature of Dante could be combined with the demon - summoning mechanics of Nocturne. The main character of Nocturne might team up with Dante to face a common threat that endangers both their worlds. Also, a crossover with a more light - hearted series like Pokémon could be interesting. Picture Nocturne's demons interacting with Pokémon in a strange new world.
One popular highschool dxd megami tensei fanfiction could be those that explore alternate universes where the characters from both series interact in unexpected ways. For example, a story might have the main character from Highschool DxD end up in the Megami Tensei world and have to navigate its complex demon - summoning and power - based society.
Definitely Pikachu. Pikachu is one of the most recognizable Pokémon, and having it interact with Arceus in a crossover would be really cool. It could be like a small, cute Pikachu following around the all - powerful Arceus.
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.
