What are some interesting plot ideas for 'Attack on Titan 2' game fanfiction?

One idea could be exploring an alternate timeline where the main characters have different Titan powers. For example, Eren could have the Colossal Titan's power from the start. Another could be a story centered around a new character who joins the Survey Corps and has a unique ability to communicate with Titans on a deeper level. Maybe they try to find a peaceful coexistence with the Titans instead of just fighting them all the time.

Perhaps the friendly titan is a protector of a certain area outside the walls that the humans have not explored much. The story could be about the Survey Corps making an alliance with this titan. The titan guards the area from other dangerous titans, and in return, the humans help the titan when it gets injured. This could lead to a whole new understanding of the titan world and how they can co - exist with the friendly ones.

One idea could be an OC who has a unique ability to communicate with the Titans. This could lead to a whole new way of dealing with the Titan threat, like trying to negotiate or understand their motives. Another plot could revolve around an OC from a different nation outside the Walls who has their own knowledge and skills regarding Titans. They could bring in new strategies and technologies.

The plot could involve a conflict within the group of titan shifters because of the tenth titan. Some might see it as a threat, while others believe it's the solution to end the war. The tenth titan's power could be something that disrupts the balance between the different factions. For example, it could have the ability to nullify the powers of other titans, which would make it a highly sought - after and dangerous power.

Perhaps the fanfiction could focus on the reactions of the other characters. For example, Eren might have complex feelings about Historia's pregnancy, as it could symbolize a new hope for humanity in a way, or he could be worried about her safety in such a vulnerable state.

Another plot could revolve around an OC who is from a different time or dimension and has knowledge of advanced technology. They could use this knowledge to try and create new defenses against the Titans. Maybe they develop a weapon that doesn't require blades and 3D maneuver gear but is more effective in taking down Titans.

One idea could be that Fem Naruto, with her ninja skills, helps the Survey Corps in a unique way. Maybe she uses her shadow clone jutsu to create distractions during Titan attacks. For example, she could send clones to draw Titans away from the main group while the Scouts make a strategic move. Another plot could involve her teaching some of the characters in Attack on Titan her chakra control techniques, which could potentially be used to enhance their ODM gear usage.

One idea could be exploring Dark Eren's internal struggle in more depth. Maybe he has to make really tough choices between his friends and his new, darker goals. Another could be a scenario where Dark Eren tries to recruit others to his side, and how they react to his changed personality.

One idea could be that the characters from Bnha are transported to the Attack on Titan world. They could use their unique quirks to fight the Titans in ways the AoT characters haven't seen before. For example, Deku could use One for All to launch himself at Titans with incredible force.

One idea could be an OC who has a unique power to communicate with Titans on a deeper level. This power could be a double - edged sword, as it might draw unwanted attention from both humans and Titans. Another plot could revolve around an OC who is a master of stealth and uses it to uncover secrets within the Walls. For example, they could discover hidden chambers or forgotten knowledge about the Titans.
