Another option could be a completely new character. This character could be someone who was turned into a permanent titan by accident or as part of an experiment. Their journey would be about adapting to this new form, trying to find a sense of identity, and dealing with the discrimination or fear from other humans. They could also become a key figure in the fight against the other titans, using their new - found titan powers in creative ways.
Armin could also be a main character in such a fanfic. He's known for his intelligence. As a permanent titan, he could use his smarts in unique ways. He might try to figure out the secrets of the titan form from the inside and communicate with the other characters in unexpected ways. For example, he could leave clues or messages for his friends using his titan abilities.
A great idea for an 'Attack on Titan' permanent titan fanfic would be to focus on the relationship between a permanent titan and a human. It could be a story of an unlikely friendship or a situation where the human is trying to study the titan to gain some sort of advantage in the fight against the other titans. The fanfic could also delve into the emotional and psychological aspects of the titan, if it has any remnants of its former human self, and how it copes with its existence.
Eren could be an interesting choice. Since he has such a complex character arc already, making him the tenth titan could add another layer to his story. He could struggle with the new power and how it changes his view of the world and his mission.
Eren could be an interesting main character in a friendly - titan fanfiction. He has a complex relationship with the titans already. Imagine if he discovers a friendly titan that changes his view of all titans. He could try to understand it better and maybe even learn to control other titans through the knowledge he gains from this friendly one.
A great plot for such a fanfic could be that Mikasa's Titan form is a result of a connection to an ancient Titan power. As she becomes a Titan, she starts to have visions of the past, of how the Titans came to be. She then decides to use this knowledge and her new form to try and end the Titan - human conflict once and for all. Along the way, she has to face her friends who are initially scared of her but eventually come to accept her new form as she proves that she is still the same Mikasa deep down, just in a different body.
Eren could definitely be a main character. He could use his Titan -shifting abilities in a unique way during the Halloween - themed events. Maybe he discovers a new power related to the spooky atmosphere. Mikasa would also be a great main character. She could be protecting Eren and the others from any unexpected threats that come with the Halloween setting.
One possible fanfic could be about Mikasa's transformation into a Titan being a unique situation in the 'Attack on Titan' world. Maybe she has different abilities compared to other Titans. For example, she could retain more of her human consciousness and use her combat skills in Titan form. This would create an interesting dynamic as she tries to protect her friends while being a Titan, which is usually seen as an enemy.
It could be the kittens themselves. Maybe there's a lead kitten that has special abilities or a unique backstory related to the Attack on Titan world. For example, it could be a kitten that was experimented on by the same people who created the titans.
Armin could also be a main character. His intelligence and strategic thinking would play a role if Sakura is involved in the fight. He might be the one to figure out how to best utilize Sakura's unique skills and abilities in the battles against the Titans, and they could form a friendship based on mutual respect for each other's capabilities.
