Armin Arlert

When he was four, his parents left on a journey outside the walls and never returned. He never learned what happened to them and lived with his grandfather until he was ten. After the fall of Shiganshina, he moved to the Trost District with his best friends, Mikasa and Eren. When his grandfather died, he enlisted in the military, later joining the Survey Corps.

When they recaptured the wall, almost the entire Survey Corps was killed by Bertholdt and the Beast Titan. In this instance, they managed to kill Reiner, and Armin ate Bertholdt, taking Floch with him when he destroyed the ceiling where he was trapped. Floch was the only murder he committed without justification. They found the basement, they found the secret about the world; Outside the walls, they lived on an island and outside of it there was a whole world to see, everything Armin and Eren dreamed of as children.

One year in the future: Eren followed her plan, but it was far less effective. They didn't have the Armored Titan, which was destroyed along with Reiner. Eren infiltrated Marley and declared war. He succeeded alongside Historia, since Zeke was dead and they would never have discussed it while he was in Marley. Historia didn't die, but she deeply regretted it; Eren had told her it would only be a warning to achieve peace with the world without wars: if they knew the power of Paradise, they would have no reason for war. 80% of humanity was eradicated. In this variation of the universe, what happens to the Titans' hosts is that they become much less conscious after 13 years from the time they inherit a Titan. By age 25, they lose most of their consciousness when they transform, and upon reverting to their human form, they suffer excruciating bone pain. Thirty years after inheriting the Titan, to escape this state they must be extracted from it with the help of others; otherwise, it will be impossible for them to return to their human form. At this point, if they remain in that form for more than a year, it will be impossible for them to return to their human form.

Armin, Pieck, Jean, Connie, Mikasa, and Annie began traveling the world to forge peace agreements, as it had been revealed that they were the ones who had stopped Eren. Armin led them, having been appointed Commander just before Hange's death.
