Ymir (Attack on Titan)

Ymir  is mysterious character of the anime/manga series Attack on Titan. She is usually seen with Historia Reiss (formerly known by her false name Krista Lenz) who is her love interest. By the story progress, its reveal she also has a power to transform into a Titan.

She is voiced by Saki Fujita (who's known for sampling her voice of one popular vocaloid, Hatsune Miku) in the japanese version and Elizabeth Maxwell in the english version.

Personality
Ymir initially a selfish, cynical, uncooperative, exploitative and confrontational. She often criticizes people for being untrue to themselves, as when she berated Sasha Blouse, who developed an extremely polite and formal way of speaking to hide her native accent.Even this, sometime she reveals her kindness side, especially toward Krista.

As the story progress, is reveal she actually brave,selfless and quite emotional.This is shown when Ymir accepts Reiner and Bertolt's offer to return to their hometown in exchange for a pardon. It should also be noted that she has shown much regret over eating Marcel, Reiner and Bertolt's friend (even though she did not have control over herself during her time as a mindless Titan). She also s.tates she is very thankful to them for releasing her from her Titan form despite this, as she deemed it an endless nightmare.

Ymir proved not only care about Krista, but also in love with her. This is shown with her promise that she will marry her after the war, asking Bertolt where is Krista in Female Titan arc and apologize at her before she leave her to save Bertolt from the Pure Titans. As a prisoner of the Marleyans, she write her love letter to her, reveal all her tragic backstory, believing she will die soon and once again apologize at her because she cannot marry her.

Although she hated the government of Marley, Ymir was actually neutral in the war between Marley and Paradis. She called Eren childish and was the only one who opposed killing Bertolt and Reiner, calling them "small fry". She was the only potential alley of the Survey Corps who opposed the killing of Reiner and Bertolt and decided to help them against Mikasa and the others, even conving Historia to stay with the two. This because Ymir knows the unfortunate position of the Warriors as Eldian pawns. She already guessed that the destruction of the Walls had been masterminded by the Marley power. And also knowing the short lifespan of a Titan shifter and how horribly Eldians are treated in Marley, she also felt sorry for her 2 kidnappers. She had to choose between staying with her beloved Historia or following Bertolt and Reiner in order to not have them suffer punishment for returning home empty-handed. However, she decided to let Historia return home, much to Bertolt's anger at first, only to find out that Eren had the Coordinate power after all, thus making the kidnapping of Historia pointless and Eren the only target.

She sacrificed herself by following Reiner and Bertolt back to Marley where she was eaten by Galliard, Marcel's younger brother, in order to give him the Jaws. She felt that she owed Marcel's life and power to his Warrior friends and brother. Bertolt and Galliard were both sorry for her unfortunate position as an Eldian and Galliard had no hatred towards her, knowing that it was beyond the control of a normal Titan to avoid eating people. Galliard thanked her for giving back his brother's Titan.
