After being brought back to Marley, Ymir willingly allowed herself to be killed and was eaten by Marcel Galliard's brother, Porco Galliard, transferring the power of the
Thirteen years after awakening her power, she died protecting the king; her corpse was then forcibly cannibalized by their daughters, Maria, Rose, and Sheena.
7 Her Power Was Divided Into What Was Known As The Nine Titans. As a reward for her services, King Fritz took Ymir in as his concubine and produced three children. After Ymir's passing, her body was consumed by her daughters in order to preserve her powers and pass it down from generation to generation.
Porco Galliard, Marcel's younger brother whom he tried to spare from life as a Titan Shifter, inherited the Jaw Titan by consuming Ymir.
She was stabbed by a spear thrown at King Fritz, and she simply gave up on life. She spent her whole life as a slave. Building Fritz's empire and bearing his children, and she just wanted it to be over. She could have regenerated, but she refused, most likely because she was tired of being a slave and wanted to die.
Odin, Vili, and Vé killed the giant Ymir. When Ymir fell, there issued from his wounds such a flood of blood, that all the frost ogres were drowned, except for the giant Bergelmir who escaped with his wife by climbing onto a lur [a hollowed-out tree trunk that could serve either as a boat or a coffin].
The choice Mikasa had to make was to hold onto her love but not be a slave to it. And that was the only way for Ymir to free herself from her slavery, let the power of the titans leave earth and to finally rest.
Initially, Ymir appeared to be selfish, cynical, uncooperative, and confrontational. However, she later revealed a kinder side, especially around Historia Reiss.
Ymir and her people were injected with the Titan serum by the Marleyan soldiers, and transformed into mindless Titans to be banished to roam on Paradis. 60 years later, still as a Pure Titan, Ymir encountered the young Warriors Marcel Galliard, Reiner Braun, Bertolt Hoover, and Annie Leonhart.
One day, Ymir was accused as a thief and was punished by the king of the Eldians, a man named Fritz, to be hunted like an animal. She ran into the woods with numerous wounds all over her body. When she hid inside a giant tree, she met a spine-like creature, and that was when Ymir turned into a Titan.
This is when the legend of the first Titan, Ymir Fritz, was uncovered, which stated that as Ymir herself was unable to live beyond 13 years after awakening her powers, no other Titan could surpass that limit.
Therefore, when King Fritz made Ymir his concubine, she truly believed he loved her. The King was also the only person from whom Ymir could receive love, and because of that, she yearned for it even more.
Ymir is a primordial giant, closely linked to the creation myth and the beginning of the world in Norse mythology. A creature resulting from the dramatic encounter between ice and fire, he was fed by a cosmic cow and his body parts served as the building blocks of the universe.
Now, it seems like the Titan Curse is gone for good as Ymir was the progenitor of all Titans. Her offspring can no longer propagate including the Power Titans.
After Ymir's demise, her daughters Maria, Rose, and Sheena Fritz devoured her corpse and gained her ability to turn into a Titan. As per their father's commands, Ymir's daughters reproduced to expand the bloodline and continue the race of humans who can turn into Titans.
Because it is impossible for anyone to surpass the Founder, each person who gained the power of the Titans was fated with the "Curse of Ymir" (ユミルの呪い Yumiru no Noroi?), which limited their remaining lifespan to only 13 years after first acquiring it.
For 2,000 years, the Founder Ymir has been waiting--a slave to those with royal blood. However, Eren's yearning for freedom gives her a choice that could shake things up.
Due to the Curse of Ymir, we know Ymir Fritz died exactly 13 years after becoming the Titan progenitor, and that makes her roughly 23-years-old when she dies protecting the King. Dying as a 23-year-old fits Ymir's chronology following her capture by the Eldians.
Despite being aware of Ymir killing Marcel, Reiner feels no hatred towards Ymir, and stays calm about the situation. Ymir is easily able to guess about Reiner's split personality, and calls it pathetic, to the point where Reiner tells her to shut up, and she quietly apologizes.
Given that Ymir had the power of all the Titans in the palm of her hand, it only goes without saying that her version of the Founding Titan was the strongest Titan in existence.
Founding Titan is the first and the strongest Titan of all the nine. If the Founding Titan is someone from Royal Bloodline, then it will possess limitless power. Eren Yeager was not someone of royal blood that's why he asked for Zeke's help to use the Founding Titan to its fullest.
What happened to Ymir Fritz in Attack on Titan? Ultimately, Ymir Fritz died protecting King Fritz from an assassination attempt. However, her death wasn't so simple, as she wound up wondering a barren land for eternity until Eren Jaeger arrived and freed her.
Fanon. People have noticed how similar Eren and Ymir are, and usually use this to compare EreMin and YumiHisu, ships that both have a hot-headed, Titan Shifter, and the other being sweet, petite and somewhat physically weak. While their interactions were limited, their friendship is somewhat popular.
Eren tells Ymir that she doesn't have to be enslaved, that she is waiting for someone to end it all. Eren asks for her help to choose him and finish everything. Another scene change happens; back at the battle, Eren's severed head grows a spin. This is similar to the creature that attached itself to Ymir.
