I am one of the people who disagreed with the ending and cannot get the ending out of my head so I'd like to make this a space to explore all possible ideas for a new ending to whomever didn't like the last chapter in a fun, creative/positive way. I know many people have a different idea of how it should have ended so feel free to share on how the manga should've ended and why it would be better if it ended that way! I'm curious (haha) to see everyone's alternative manga end too.

Here are mine. I try to outline what makes each ending work and their potential problems:

Aaron Yogurt timeline/EM ending: Eren runs away with Mikasa like in ch 138 to a cabin somewhere in the woods. After running away with Mikasa, Eren uses the Founding Titan to go back and fix something in the past or control the titans in a way that could protect Paradis from afar. Mikasa and Eren live with eachother, they have a baby, and Eren dies after 4 years with the "see you later Eren" panel.

Bonus ending: If they wanted to go dramatic tragedy, they could go RDR ending where they are found, Marley/outside invaders attack, Eren uses all his attained titan powers to fight armies until death while Mikasa and their child run away. Ends with a strong tatakae message as Eren makes one final stand for his family. Straight rip off from RDR but fun to think about!

Why this ending works: Although it's a version of Eren made by Mikasa's imagination, this could make sense if ch 139 Eren really said what he meant that he loved Mikasa.

Side note- Honestly, ch 138 Eren is so much better than ch 139 Eren imo. At least he had the balls to go for his goal and get with Mikasa in a controversial way of abandoning Paradis to Marley and abandoning his friends. At least Mikasa doesn't end up depressed until death and has a reason to live once Eren passes: to take care of their child. It's also good for Eren, because he got the freedom to do what he wanted and was not pressured to do something he didn't want to do.

Potential problems: The problem about this ending for it to happen is their rapport needed to be built more so it doesn't feel forced, but it isn't impossible from where they are in the basement chapter which was where their reciprocation started. Also what happens with the rumbling and Paradis? How could they end the titan curse? This could be the most selfish out of all endings for them to run away from their homeland instead of fighting, but it still reflects the core message of Eren's philosophy of true freedom.

Again not the best ending, but it's plausible and an option. To me, it'd be much better than the current ending.

Complete Rumbling/EH ending: Mid rumbling, Eren gets a breakdown after killing the whole Alliance with his friends included yet chooses to move forward for his hometown. Eren destroys the whole world with the rumbling, everyone in Marley to stop all wars. He finally breaks down like in ch 139 after everyone is dead, goes back to Historia and his reborn child Ymir on Paradis and spends his days carrying the guilt, but is relieved that the rumbling is done. Probably the ending that makes more sense.

Why this ending works: It's align with Eren as a character and is consistent throughout. This version of him keeps moving forward until the rumbling is complete. It targets the initial goal for Eren to start the rumbling which was if people were not born, they could never feel pain. Eren may not have wanted to do it, but he did what was necessary to protect his friends and the land he was born on. Targets the core themes in AOT of fighting, sacrifice, and freedom.

For EH shippers, they get their wish and it makes the most sense for them to be together. It's a very bleak ending as its a view of wastelands stretched by acres and the amount of bodies would be crazy, but no wars and permanent peace. Since it looked like it was about to go this route, not many changes are needed to be made. Just have Eren control all titans to kill each other including the remaining alliance members after ch 138. If everyone including all titans are dead, the titan curse is broken.

I'd be really interested to see this ending, because I've seen no anime or manga do that before, but sadly it didn't turn out the way it did.

Potential problems: It's a controversial ending as it ends with total genocide of the whole world. Also very sad for EM shippers.

Those were my alternate endings to the manga that I think may have been better. Some things may or may not be entirely accurate, but it's all for fun in the end. Join me to use that strong energy in a creative and productive way instead of suffering from the last chapter ending. Your imagination here is free!
