Ymir (Anime)

Ymir (ユミル) is a graduate of the 104th Cadet Corps and member of the Scout Regiment.

Human Form
Ymir is a tall, slender young woman with parted hair often styled into a ponytail and intimidating eyes. She has straight, long, brown hair held back with a red tie and golden eyes, as well as a slight tan.

Personality
Initially, Ymir appears selfish, cynical, uncooperative, exploitative and confrontational, but later reveals kindness, especially around Christa Lenz. She often criticizes people for being untrue to themselves, as when she berated Sasha Braus, who developed an extremely polite and formal way of speaking to hide her native accent.

History
Ilse Langnar, a member of the Scout Regiment that resembled Ymir, encountered a Titan that spoke of her as a "subject of Ymir." This Titan mistook Ilse for Ymir, and bowed before her while referring to her as "Lady Ymir." Ilse's notes of the encounter were later discovered by Hange Zoë and are the first hints of Ymir's true nature.

Humanity's Comeback arc
On the first day of training, Ymir and Krista venture outside and fetch refreshments for Sasha after her 5 hour-long run as a punishment. Ymir acts apathetic and shows little care for Sasha's well-being, telling Krista that she could use Sasha's stupidity to her advantage.

Ymir graduates in the 104th class outside the top 10, which Krista deems that she deserved to be there more than her. It is implied that she intentionally gives less than her full effort so that Krista could have the 10th slot. After graduation, she follows Krista into the Scout Regiment.

The Struggle for Trost arc


Ymir is in the Trost District when the Colossal Titan breaks down the gate. She is part of the squad that discovers a catatonic Armin, and mocks him upon learning that he is the only survivor. This results in a brief and heated exchange with Conny Springer, before Krista steps in to mediate. In response, she requests that Krista marry her once the battle is over. She is later among the squads able to retreat over the Wall when the order was given, and waited on standby for further orders.

Abilities
Ymir possesses great physical ability - she shows to be fully capable in combat and use of weapons. During her time as a trainee, it has been rumored that she started slacking off to ensure Christa Lenz a spot in the top ten.

Relationships

 * Christa Lenz - She is romantically attracted to Christa, and utterly devoted to her. Her primary goal is to protect her no matter the cost. The two have a strong connection, and deeply trust each other even while keeping secrets.
 * Reiner Braun and Bertholdt Hoover - Ymir agrees to become their ally, and work with them in exchange for Christa's safety. She expresses that she does not trust them entirely, and believes that even if she cooperates with them, she will eventually be killed by their "warriors". When they attempt to flee without kidnapping Christa, she makes it clear she will fight them to the death if they do not give into her demands. When things look bad, she quickly abandons them and considers leaving them to their fate. However, for an unknown reason she decides to leave Christa behind in order to come to their aid. It is later revealed that she feels a sense of gratitude towards them for accidentally triggering her return to human form, and she states that she is the only one capable of understanding their circumstances, as they are "the same". She further states that she wishes to "return what she took from them" and insists on returning to their hometown as their prisoner.
 * Conny Springer - Conny is an antithesis to Ymir; Ymir is wily as Conny is obtuse. Ymir is selfish as Conny is empathetic. Conny has many friends as Ymir only has Christa as her friend. Inevitably they have an antagonistic acquaintance, often exchanging verbal barbs with each other. They have repeatedly clashed (one incident almost physically), as Ymir often made him the target of mockery and he called her pejorative names due to her haughty attitude. Even so, it would not be right to say that they are on completely bad terms; as Conny is quick to defend her when she appears before the soldiers in Titan form. Later, when he encounters her again during battle, he tells Christa that Ymir only acts seriously when it comes to protecting her, showing that even after her apparent betrayal, he still believes in her.
 * Sasha Braus - Ymir is not ashamed to take advantage of other people, especially if they are naive and simple-minded. She initially helps Sasha back to bed after she collapsed in exhaustion, and uses this to make Sasha feel indebted to her. It is shown that she often pushed her chores onto Sasha, but she also was the one to confront Sasha over hiding her real dialect/accent and demand that she not be ashamed of her roots.

Trivia

 * Her name is the very same as a primeval being in Norse mythology who is the progenitor of all Jotun, or ice giants, and the first living being. Ymir also means "the scream".
 * The official website mentions Ymir is in love with Historia (Krista). Also at the series panel for Animagic 2014, producer George Wada confirmed that Ymir and Krista are a couple.
 * Since Ymir is not given her true name in the first season of the anime, she is given the name "Freckles" (そばかす) during the credits.
