Attack on Titan Chapter 139 will be the last and final installment to Hajime Isayama's massively successful brainchild. As there are still a lot of plot points that the series has to conclude in a single chapter, how can the mangaka do it?

There are many questions as to how Isayama will put every character's story and the manga's general storyline in Attack on Titan Chapter 139 to a close. With a lot of theories here and there, these are how things may end.

According to BlockToro, Ymir may reset everything after witnessing the love of Eren and Mikasa. There are also theories that Historia's baby is the reborn Ymir, who will create a new world where Titan and humans can live in harmony.

There may be a major time-jump or alternate reality, featuring the manga's end where everything is resolved through some "deus ex machina." The fights may stop after Eren meets his demise.

They may finally realize that Titans are not the real enemies, but themselves in Attack on Titan Chapter 139. The differences they have with each other make matters worse, resulting in being the source of every problem.

Elsewhere, Eren and Mikasa may start spending the rest of their lives in the Paths together, while the Rumbling is destroying everything outside Paradis. At the end of it all, everyone who has turned into Titan will return to their human forms, and Titans will be wiped out.

OtakuKart News added the final episode might be intended for Mikasa, but there would surely be a lot in play. It might start with Eren waking up from a bad dream crying.

This may feature the possible reset that Ymir may do, giving them a second chance in life and putting everything back to normal. Attack on Titan Chapter 139 may also reveal the birth father of Historia's baby.

Talking about the series finale, Isayama couldn't believe that the upcoming installment would be the last of the manga. The manga artist had been working on the manga for more than a decade, featuring the significant change in Eren's life, from a hopeful soldier who wanted to kill all the Titans to avenge his mother's death to turning into a Titan himself and wreaking havoc all over the place.

Fans still have to wait for almost a month before they see the manga's conclusion. Attack on Titan Chapter 139 is set to be out on Friday, April 9, per HITC.
