That being said, as the founder of all Titans, Ymir has the ability to force her will onto her subject. And since Ymir can only use the Titan's power for 13 years, then every Eldian who received her Titan power would also only have 13 years to live their life. And that is the curse of Ymir.
It is said that nobody can surpass Ymir and that because Ymir died 13 years after awakening her powers, no one is allowed to live beyond that; this phenomenon is known as the "Curse of Ymir." After Ymir's death, her spirit lived on in a world where the Coordinate resides.
No, because the 13 years of life span is part of the curse of Ymir. Eren choose the path of mostership in order for Mikasa Ackerman to become an example to Ymir. Ymir Fritz is now free and Titan Shifting Power is already gone and all remaining Pure Titans turn back to human.
After the manga had ended, it can be concluded that the Curse of Ymir is actually a lie, and no titanshifter actually died from the curse.
Though the Curse of Ymir has not been explained or even proven, it's effects have been seen on previous inheritors of the Nine Titan powers, such as Eren Kruger.
Armin is the one who confirms the curse is done when he awakens from a conversation with Eren in the Paths. When Mikasa shows up, he admits to remembering his chat with Eren, and he told the heroine her decision to free Ymir through Eren's death brought freedom to all.
The creature that turned Ymir into a titan was the hallucigenia-like creature, as stated in the manga. It is said to be a giant version of a real life creature that lived millions of years ago.
The Shining Centipede, or Centipede-kun as it's affectionately known to fans, is the insectoid entity that grants Ymir Fritz the Power of the Titans.
The story of how Ymir got her powers varies among different regions. Among Eldian cults, Ymir was viewed as a goddess. However, the Marleyans saw Ymir as evil and were under the assumption that her powers came directly from Devil since she wiped out all of their forces during their war against the Eldians.
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.
This means that all titan shifters that survive the final fight won't die from the Curse. So Eren, Armin, Falco, Reiner, and Annie are safe from this threat.
Though she loved King Fritz, the anger from being oppressed burned within Ymir, and opting not to heal herself represented a means of escaping that terrible existence.
The Attack on Titan fandom still can't come to a consensus about the Curse of Ymir, a rule which states that a Titan Shifter can live a mere 13 years after acquiring their Titan powers, and what this means for our protagonist, Eren Jaeger, who possesses more than one Shifter power.
But, in the process Ymir Fritz became too obsessed with power she possessed and decided to conquer the world. Therefore, she became evil.
Ymir was actually a fraud, as she had no royal blood and she was only a homeless Eldian little girl taken from the streets by the scammer.
There is no doubt that Ymir suffered a lot, and it might feel ridiculous to think of her as evil. But she did make a lot of questionable choices. She could simply have killed Fritz and ended his reign. But she didn't do it because she loved him, which caused thousands of years of misery for people throughout the world.
Before the operation to retake Wall Maria Keith Shadis tells Eren that he first met Grisha about 20 years ago. At this point the attack on Wall Maria which coincided with Grisha's death happened 5 years ago. So Grisha had in fact been inside the Walls for 20-5 = 15 years!
Ymir was evil, and all the generations of evil frost giants in Norse mythology descended from him.
According to AOT's website, Eren Yeager is 19 years old in this final season. Mikasa Ackerman is also 19. An important thing that many AOT fans might already know is that the Ackermans meaning Levi and Mikasa are special, they do not undergo ageing like others do.
No, the Eldians need to consume a Titan Shifter in order to become one. If Eren dies without being eaten, then the Titan Shifters die with him.
Eren currently possesses the powers of the Attack Titan, the Founding Titan and the War Hammer Titan. He still has only four years left to live. This is known as the Curse of Ymir. I believe it was caused when Ymir was slaughtered originally.
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 Jaw Titan to him.
Ymir needed them because she was only a child who was the victim of terrible abuse. She needed Eren to help her free up all her pent up anger at the world because of what she experienced. She needed someone that understood her and could relate to what she went through.
She transforms into a Titan at 10, spends 8 years or so dominating Eldia's neighboring countries, bears King Fritz's children at 18, then dies at 23 when her own children are around the age of 5.
Zeke Yeager, otherwise known as the Beast Titan or just The Beast, is the main antagonist of the Attack on Titan series.
