Linense wrote: I really love your theory, and it would be a very great twist plot. If so, I would love to see the surprised faces of the members of the Disney alliance when they see that they are facing a Zeke controlled by Eren's founding titan and not Eren himself, so that he begins to attack them from behind, perhaps with the help of the Yeagerists (that might be the perfect way for Floch's comeback, in case he's not hidden in the plane).

There's also the possibility that Eren will devour the other changing titans to become the only changing titan, like in the days of the founder Ymir, and although I see it feasible in almost all of them, I don't know how he would manage to devour Armin if he is transformed (emotional conflict aside, because Armin has been Eren's best friend for most of his life). We already saw in the battle of Shinganshina that Eren did nothing to Berthold when both were transformed. Eren had to resort to Armin's plan to trick Berthold out of the colossal titan, but he never had a chance to get him out when he was transformed. The only thing I can think about it is that he would need help from the Yeagearists to set a trap against Armin where he will trip and fall, and then the attack titan could devour Armin.

There is also a possibility that Eren managed to devour everyone else and let Armin devour him so that his friend managed to gather the 9 Titans into one (after all, Armin is the narrator of the anime and that had to be an exclusive decision of Isayama).

PS: By the way, I want you to take a look at this thread that I recently created and give your opinion on it, to see what you think. https://attackontitan.fandom.com/wiki/Thread:71778

What I say there could also serve after the last battle, in case Eren is victorious, so instead of paying homage to Erwin so much, Eren would be the most honored. Agreed, while there are possibilities of Eren Yeager getting devoured by Armin Arlert. There is also a possibility that Eren Yeager may have found another way, better one from Ymir, where he could extract those powers without killing anyone. It is possible that when Ymir offered her powers to assist Eren Yeager, she may have given him her entire power willingly. After all, whenever those inheritors dies (from battle or Ymir Curse), titan powers returns to the coordinate where they are relocated into a newborn Eldian baby. Perhaps Eren Yeager is now the new coordinate and figures out how to acquire titan powers without killing anyone who inherits them.

PS: I have looked at your thread and left a comment for you.
