Eren Yeager would be an obvious choice. His complex personality and his connection to the Titans make him a central figure. Mikasa Ackerman is also interesting as she is so loyal and skilled. In a two - world fanfic, you could also include characters from the second world that are counterparts to them. For example, a character who has the power to communicate with Titans in a different way than Eren.
Levi Ackerman is always a fan - favorite. His badassery and combat skills would add a lot to the fanfic. Armin Arlert too, with his intelligence. In the 'Two World' aspect, it would be cool to introduce a character from the other world who is a Titan shifter but has a completely different moral code. This character could clash or team up with Eren, creating some really interesting storylines. There could also be a character from the second world who has the ability to see the future, which could help in the fight against the Titans.
I think Historia Reiss could be a very interesting character to include. Her backstory and her role in the original series give her a lot of potential for development in a fanfic. For the 'Two World' part, imagine a character from the other world who is a healer but also has a dark secret related to the Titans. This character could interact with Historia in various ways, like teaching her new ways of using her power or having a conflict over different ideologies. Additionally, Jean Kirstein could be included as his growth from a self - centered person to a more selfless one can be further explored, especially when he is faced with new challenges in the two - world scenario.
Eren is often still a very popular character. His determination and complex character traits translate well into a real - world fanfic setting. Mikasa is also popular, her loyalty and combat skills make her a standout. Levi too, his badassery and leadership qualities are appealing to fans in this type of fanfic.
Eren Yeager is fascinating. His transformation from an ordinary boy to someone with a strong will to fight the Titans is a major part of the story. His complex relationship with his friends and his inner turmoil make him stand out.
One idea could be exploring an alternate world where the Titans have different abilities. For example, some Titans might be able to fly or control the elements. Another plot could revolve around the characters from the original 'Attack on Titan' being transported to a completely different world with its own set of rules and threats. Maybe in this new world, the Survey Corps has to form alliances with strange new creatures to fight against a common enemy.
Mikasa is quite popular too. Her strong bond with Eren and her own combat skills make her an interesting character to write about in fanfiction. Armin also gets a lot of love. His intelligence and his role in strategizing against the Titans are often explored in fan - created stories. There are also some less - known characters from the series that gain popularity in fanfiction, like Sasha, because of her unique personality.
Eren Yeager is extremely important. He is the main protagonist and his transformation into a Titan is a key part of the story. Mikasa Ackerman is also crucial. She is a very strong fighter and has a deep bond with Eren. Levi Ackerman is important too. He is known as humanity's strongest soldier and plays a vital role in battles against the Titans.
The character interactions are great too. Imagine the stoic and highly - trained Gundam pilots meeting the passionate and often reckless Survey Corps members. Their different personalities and values can lead to some really engaging dialogues and character development. Some fanfics explore how they learn from each other, like the Survey Corps learning about more strategic combat from the Gundam pilots, and the Gundam pilots learning about the importance of hope and determination from the characters in Attack on Titan.
Eren Yeager is extremely important. He's the main protagonist and his journey from a young boy seeking revenge against the Titans to a key figure in the fight is central to the story. Mikasa Ackerman is also important. She's a highly skilled fighter and has a deep bond with Eren. Levi Ackerman is another crucial character. He's known for his incredible combat skills and leadership within the Survey Corps.
Eren Yeager is often a popular character in these fanfictions. Given his central role in the original story, his reincarnation can lead to many different plot developments. Mikasa Ackerman is also popular as her relationship with Eren can be explored in new ways through reincarnation. Levi Ackerman is another favorite. His badassery remains intact even in reincarnation scenarios, and his skills can be used in different ways depending on the new storylines.
Armin Arlert is one of the main characters. His intelligence often helps the group in difficult situations. Historia Reiss has a significant role as well. She has a special connection to the secrets of the walls. And of course, Eren Yeager. His actions drive much of the plot forward as he's on a mission to destroy all Titans.
In 'attack on titan the gamer fanfiction', Mikasa is probably a popular character. Her loyalty and combat prowess are well - known in the original work, and in the fanfiction, she could have unique gaming - related abilities. For example, she might have a special 'tracking' ability in the gamer world. Armin is another one. His intelligence could be enhanced in the fanfiction with the gamer concept, like being able to analyze Titan patterns more efficiently as if he was using a game - like skill.
