Yelena

Yelena (イェレナ) is an ally of the Survey Corps, formerly a soldier of Marley who was a part of the first survey fleet after the failed Paradis Island Operation.

Appearance
Yelena is a very tall woman with her blonde hair in a bowl cut. She has large, black eyes and somewhat androgynous features. She wears the standard Marleyan military uniform.

Personality
She is a fervent follower of Zeke Yeager, holding great admiration and respect for him. She is usually calm and collected, her demeanor remaining unchanged even when Jean Kirstein yelled at her for failing to see her job through. Nonetheless, she is willing to take responsibility and apologizes should she fail in her task.

Marley arc
Using a fake beard to disguise her appearance, she pretends to be a Marleyan soldier and arrives at the Warriors' seating area during Willy Tybur's production. Declaring that Magath called for them, she asks that Pieck, Galliard, and Zeke follow her. Soon after, she sends Zeke off in another direction while continuing to lead the other Warriors. They stop temporarily when Pieck suddenly hugs one of the Panzer Unit soldiers they meet on the way. She leads them into a room, where she traps the two in a hole.

At the end of the Battle of Liberio, she joins the rest of the Survey Corps on the blimp. Standing in a room along with Zeke, Eren Yeager, Armin Arlert, Levi, and Mikasa Ackerman, she takes her fake goatee off when Levi asks her too, commenting how people seemed to like it. They are soon joined by Jean Kirstein, who brought the recently captured Gabi Braun and Falco Grice. Jean yells at her for not carrying out her duty of locking up the Jaw and Cart Titan, causing more soldiers than necessary to die, for which she accepts responsibility.
