Attack on Titan is a popular Japanese manga and anime series that has gained a large following worldwide. The story follows a group of humans who live in a world overrun by giant humanoid creatures called Titans, and their struggle for survival and freedom. The manga, written by Hajime Isayama, began serialization in 2009 and concluded in April 2021, while the anime adaptation has been ongoing since 2013.

The AOT ending has been a topic of discussion and speculation among fans for years, and the anticipation only grew with the release of the final manga chapters in 2021. While some fans have expressed disappointment with the ending, it is important to remember that the story is the creative vision of the author and ultimately reflects their intentions for the narrative.
It is highly unlikely that the AOT ending will change in any significant way. Once a story is completed and released, it is generally considered final and cannot be changed. The author may make minor revisions or corrections for future releases, but the overall plot and conclusion remain the same.
It is also worth noting that the AOT anime adaptation has followed the manga closely, with few deviations from the source material. While some anime adaptations may make changes or alternate endings for various reasons, such as budget constraints or creative differences, this is not the case for AOT.
In conclusion, based on the available information, it is unlikely that the ending of Attack on Titan will change. While fans may have their own opinions and preferences for the narrative, it is ultimately up to the author and creative team to determine the direction and conclusion of the story.
