What are the common themes in AOT time travel fanfiction?

One common theme is redemption. Often, the OC is used to give Bertholdt a chance at redemption for his actions in the original series. Another theme is friendship. The OC forms a strong bond with Bertholdt, showing a different side of his personality.

Survival and hope are also prevalent themes. Since the original Attack on Titan story is quite dark, in alternate endings, fans often write about how the characters find hope in the most desperate situations and strive for survival in different ways. For instance, they might find new methods to deal with the Titans or new ways to build a future for humanity that doesn't involve constant bloodshed.

Another theme is the exploration of different time periods within the show's universe. This allows for new settings and character interactions.

One common theme is physical injury during battles. Given Levi's role as a strong fighter in AOT, fanfictions often explore scenarios where he gets seriously injured in combat, like being wounded by Titans or in fights with other humans. This could lead to his comrades having to take care of him, creating moments of vulnerability and bonding.

The theme of redemption also shows up. The Winter Soldier may see his time in the AOT world as a chance to atone for his past actions. He uses his abilities to protect the people in the AOT world, and in doing so, he starts to find a sense of purpose and redemption that he may not have had before.

The theme of destiny is quite common. Ash may travel through time to fulfill a certain destiny that he was unaware of in his normal timeline.
