How does the 'attack on titan alternate ending story' differ from the original ending?

There's a chance it could be different. The anime might want to surprise the audience or adapt the ending to better suit the medium of animation. But we'll have to wait and see.

Well, in the original ending, Iron Man snaps his fingers to defeat Thanos and his army. But in the fanfiction, it could be someone else doing it. For example, Hulk could have found a different way to use the Infinity Stones that didn't require self - sacrifice.

Well, the original ending was quite tragic. In contrast, the alternate ending in the fanfiction might be less so. It could have changed the fate of the main characters, perhaps keeping them alive and together in a way that the original didn't.

It might also mean a change in the overall world - building of Attack on Titan. The alternate ending could have a different origin for the Titans or a different relationship between the humans and the Titans. Perhaps instead of being enemies, they find a way to coexist in this alternate story.

The ending of AOT in the manga is quite controversial. Some fans loved it, while others were disappointed. It involves complex plot developments and character decisions.

In the game, the story is more interactive. While the anime just shows the events, in the game you can directly influence the outcome of battles. For example, in the game you can choose different combat strategies against Titans.

Yes, it is. The anime's ending has some noticeable differences from the manga that have sparked a lot of discussions among fans.

It might differ in the character development. For example, some minor characters in the original series could be given more in - depth backstories and important roles in the fanfiction. This can change the overall feel of the story.

It might have updated characters with more modern personalities.

There are some differences, but not too significant. The anime generally follows the main plot of the manga.
