30. Attack on Titan: The Final Chapters (Part Two)

Complete story — includes the ending

Chapter 3 – The Battle of Heaven and Earth: The Scouts and Warriors land on Eren's rib cage and incapacitate the Beast Titan, but quickly realize that it is just a shell with Zeke himself nowhere to be found. Before Armin has a chance to transform, he is captured in a Titan's mouth. Suddenly, countless versions of the Nine Titans of the past appear on Eren's back, created by Ymir Fritz to defend him. Just as the Scouts and Warriors are nearly defeated, Annie and Gabi appear on the back of Falco's new flying Jaw Titan. Meanwhile, Armin discovers Zeke in the Paths. Chapter 4 – A Long Dream: Armin and Zeke have a conversation about the meaning of life, and Armin convinces Zeke to share his viewpoint. The two call on the deceased Titan shifters throughout the series to help the alliance; Zeke then materializes on Eren's Titan and allows Levi to kill him, stopping the Rumbling. After Armin is rescued, he uses the power of his Colossal Titan to destroy Eren's Founding Titan, releasing the centipede-like organism, the source of all Titan power, from Eren's nape. Falco flies down to the Liberio refugees, but the reunion between the Warriors and their families is cut short when the source turns the nearby Eldians, including Jean, Connie, and Gabi, into Titans to help defend it. Reiner, Annie, and Pieck engage the Titans and the source to prevent it from reconnecting with Eren, who transforms into the Founding Titan once again to fight Armin; this leaves Mikasa and Levi as the only ones left who can take Eren down. Jumping off of Falco's back, Levi uses a Thunder Spear to destroy Eren's Titan's front teeth, exposing his human form within, before Mikasa rushes in and beheads Eren. Ymir is subsequently freed from the Paths, allowing her to pass on, and the Titan powers, along with the source, disappear from the world. All Eldians are permanently turned back into humans. Final Chapter – Toward the Tree on That Hill: After Eren's death, a conversation between Armin and Eren is shown where Eren talks about why he treated Armin and Mikasa badly earlier, the effect his possession of both the Founding and Attack titan had on his mind, the revelation that eighty percent of the world's population will be wiped out by the end of the Rumbling, and his realization that it was impossible for him to avoid doing the Rumbling. After repeatedly trying to find a way to avoid the Rumbling, Eren decided to go along with it to protect his friends and ensure their statuses would be elevated to the saviors of humanity in the rest of the world, alongside giving them the long, fulfilling lives he wanted them to have in a world free of Titans. As it ends, it is revealed that the conversation had taken place much earlier but Armin's memories of it were suppressed by Eren until Eren's death, and that Eren did the same with the rest of his former friends. After mourning their friend, Armin decides to take credit for killing Eren so as to cover for Mikasa leaving to bury Eren's head on Paradis, and the Scouts and Warriors are hailed as heroes by the survivors of the Rumbling. Three years later, with eighty percent of humanity decimated, the Jaegerists become the dominant faction of Paradis' military and prepare for a potential future attack from the rest of the world, while the remaining Scouts and Warriors become the world's ambassadors for peace negotiations with Paradis. Mikasa, who had buried Eren's head under a tree that he would frequently rest under as a child (the same tree the show starts near), continues to visit his grave throughout the rest of her life. Many generations pass peacefully before a futuristic Paradis is bombed from above and destroyed in a war. Over time, Paradis is reclaimed by the wilderness, and within this wilderness a lone boy and his dog approach the tree Eren is buried beneath, which has since grown to resemble the original tree that contained the source of the Titans' power.
