Yelena [Zombie Apocalypse.]

Species Human Gender Female Affiliation Anti-Marleyan Volunteers Former occupation Soldier Former affiliation Marleyan military Appearance: Yelena is a very tall woman with her blonde hair styled in a short bob with straight bangs. She has large dark gray eyes and somewhat androgynous features due to her build and style. She also sports a chinstrap beard, which is later revealed to be fake. Originally, Yelena wore the standard Marleyan military uniform, but after disaffiliating she began wearing a casual white button-down with a dark blazer and pants. Personality: Yelena is a deeply intense and driven character, with a personality shaped by her unshakeable beliefs and fierce loyalty to her ideals. One of her most defining traits is her near-religious reverence for Zeke Jaeger. To Yelena, Zeke is not just a leader but a visionary with a grand plan to free the world from suffering, consisting in euthanizing all Subjects of Ymir in order to end the Titan powers once and for all. She sees him as a prophet, a savior, even a God, with the power to reshape history, and this admiration borders on idolatry. Her loyalty to Zeke is absolute, and she sees herself as a chosen disciple helping him achieve his goals. And many have noted that Yelena is somewhat deranged in her zealotry; if any of her comrades are thought to be working against their goals or insult those whom they are ultimately trying to save, Yelena will come forth and kill them without hesitation. Her admiration for Zeke also led to her considering his half-brother Eren as a God too, when she still believed that he was agreeing with Zeke's plan. She considered that the two would have been praised like ancient gods by humanity for millennia's to come if the euthanasia plan came to fruition, for having freed the world from the horrors caused by the Subjects of Ymir's Titan powers.

Her hatred for Marley, her country of birth, is intense and unyielding. She views Marley as an oppressive, cruel nation that has spread suffering across the world, and she feels no loyalty or affection for it. Instead, she despises Marley and has no shame in insulting her fellow countrymen, if they actively contribute to the country's imperialistic actions, such as its soldiers. This hatred fuels her commitment to Zeke's plan, as she believes that Marleyan imperialism must be stopped to end the cycle of violence and oppression. It can also be argued that she is a sociopath, basking in the destruction of numerous airships and countless people while smiling and on the verge of tears. Despite the disdain she developed for her own homeland, she still desired to save Marley from this endless cycle of suffering, believing that Zeke's euthanasia plan would achieve that. Yelena also has complex feelings about the Subjects of Ymir. She does not hold personal prejudice against them, but still sees them as part of a larger problem. In her eyes, the cycle of Titan powers, linked to the Subjects of Ymir, has caused endless conflict and suffering. While she does not harbor any personal hatred toward them, she believes that Zeke's euthanization plan is a necessary solution to end the pain once and for all. Even with Zeke having been defeated by his brother Eren, she still believed that his plan was the right one, as evidenced by Eren going through with the Rumbling for the sake of the Eldians of Paradis Island. And even years after his death, Yelena continued to mourn Zeke, demonstrating how deep the love she felt for him was. Born into an unassuming family in Marley, Yelena eventually became disillusioned with her own country. After meeting Zeke Jaeger, Yelena concocted a plan to solidify herself in history by assisting Zeke in saving the world.

As part of her narrative, Yelena created a false background for herself, claiming that her homeland was invaded and conquered by Marley. She was forcibly drafted as a soldier to fight in the Marleyan military, where she met similar-minded soldiers and organized them into the Anti-Marleyan Volunteers to fight against Marley.

During the Marley Mid-East War, Yelena and her comrades are placed in a situation where they completely lose their will to rebel against Marley. However, Zeke saves them from the clutches of death, rejuvenating their fighting spirit, and inspiring Yelena. She becomes a devoted follower of Zeke, to the extent that she considers him a God. She and her group join with Zeke and begin planning a rebellion in earnest. As she works with Zeke, she and the other members of the Volunteers are notified by Zeke of his half-brother Eren, who has possession of two Titan abilities. Yelena volunteers to go to Paradis Island as part of the crew serving aboard a survey ship. In 851, the ship arrives at Paradis and is promptly captured and beached by Eren's Titan form. They are confronted by Hange Zoë, offering to negotiate with them. When her commanding officer refuses to listen, Yelena promptly kills him and, along with Onyankopon, accepts Hange's offer to talk. Meeting with Hange and Levi Ackermann, Yelena and Onyankopon allow the two to inspect their weapons, explaining that Marley has not yet launched a full assault on Paradis Island due to a war they are currently caught in. Hange guesses that Yelena and her comrades are sleeper agents who have infiltrated the Marleyan army, but Yelena explains to them that they are simply conscripted soldiers who have chosen to rally around Zeke Jaeger in opposition of Marley as the Anti-Marleyan Volunteers. Forming an alliance with Paradis Island, Yelena and her comrades begin sharing their technology with the islanders and prepare to fight back against Marley.

Around one year later, the Anti-Marleyan Volunteers arrange a meeting between Paradis and the Azumabito family to discuss an alliance. While waiting for the family to arrive, Yelena gets a chance to see Eren. She is ecstatic to finally meet him, and despite not being allowed to interact with him, declares that it will be a good day. As the Azumabito family arrives, Yelena calls Mikasa Ackermann's attention to their appearances, explaining that they resemble Mikasa's mother because they are related to her. While attending a banquet to celebrate the opening of the rail system in Trost District, Yelena's personal guard is abruptly changed, being replaced by Floch Forster. This allows her to slip away unnoticed and meet with Eren in private. Both having grown impatient with the military's perceived lack of urgency, they easily come to an agreement that something needs to be done to stir up the military and push it to action; she mentions to Eren the basic premise of Zeke's plan and states that he wishes to speak with Eren about it in greater detail. At about the same time, Yelena began distancing herself from the other Volunteers and arranged with Zeke to have numerous bottles of wine mixed with his spinal fluid sent aboard the survey ships to Paradis. She meets with Nicolo and tells him the wine being brought in are to be distributed and given to all those the military, especially the more senior members and leaders. During one of her meetings with Eren Yelena discussed with Eren her and Zeke's true intentions to "save the world" with the euthinazation plan and urged him to their side, with Eren agreeing on the surface keeping his true intentions hiden. In another meeting Yelena made plans to use a partial rumbling to crush Global Allied Fleet as well as Fort Salta with Eren.

In 854, after their forces receive word that Eren Jaeger is planning on launching a full-scale attack on Marley, she is among the forces Paradis Island dispatches to retrieve him. Yelena disguises herself as a Marleyan soldier from the Lakua military base in the west and arrives at the Warriors' seating area during Willy Tybur's production. Claiming 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 that they meet on the way. She leads them into a room, where she traps the two in a hole. After returning to Paradis, Yelena and her fellow Volunteers turn over a stock of Titan serums they managed to steal from Marley to the Garrison. After receiving the serums, Dot Pyxis has his soldiers capture the Volunteers, revealing that Paradis is not willing to trust Zeke and his followers yet. Yelena is unconcerned with the betrayal, confidently declaring that the Volunteers and the Eldians will soon dine at the same table. After some time in confinement, Yelena receives a visit from Pyxis. Yelena quickly admits to meeting with Eren, apologizing for keeping the meeting a secret. She claims that she only met with Eren to persuade him to do something that forces the military into action, but Pyxis points out that she could have just talked to the military directly. He accuses her of trying to influence Eren to Zeke's will, but Yelena passionately argues that she did not, and that she only wanted to meet Eren out of curiosity due to his unique traits as the Founding Titan and as Zeke's brother. Revealing that none of the other Volunteers were aware of her meeting with Eren, Yelena claims that she only wants what is best for Eldia. Pyxis remains unconvinced, telling her that she is a terrible liar.

After the military's officials learn that they have unwittingly been drinking Zeke's spinal fluid, many of them defect to the Jaegerists so that they will not be turned into Titans. As a result, Pyxis is forced to surrender unconditionally to the Jaegerists, and is brought to speak with Yelena.

Yelena begins the meeting by reminding Pyxis of her promise that the military and the Anti-Marleyan Volunteers would soon dine with each other again. She remarks how glad she is that Pyxis ordered no resistance to their demands and agreed to meet with her, but Pyxis points out that he is only complying because his hand has been forced. He goes on to remark that the Jaegerists' strategy of marking Eldians who were quicker to join their side is strikingly similar to Marley's systems of oppression, but Yelena is unfazed by the comparison; she stares at Pyxis and reminds him that they refused to join the Volunteers, lamenting that the world would already be saved were it not for the military's overly cautious nature. Pyxis is confused by her statement, pointing out that releasing the Colossal Titans would only save Paradis, but Yelena refuses to clarify her statement. Instead, she glares at Pyxis and condemns him for trying to have Zeke killed, promising that she will punish the Eldians of Paradis for their actions. She then travels to the cell holding the captured Scouts and again regrets that they are meeting behind bars again. Yelena takes offense when Greiz begins insulting the memory of Sasha Braus and promptly shoots him when he calls her a filthy whore and an island devil. She apologizes for his rudeness and, pulling up a chair, decides to reveal the specifics behind the euthanasia plan.

She begins to glorify how Eren, and Zeke will be spoken of as symbols for thousands of years and is glad to hear Armin state that he was moved by her words. Just then, Yelena is shocked to hear from a Jaegerist that someone managed to infiltrate their ranks. Going to meet Eren on top of the building, she is surprised to see Pieck and Gabi with him; as they are led to the edge of the roof, Yelena shares with Eren how he should not trust Pieck. As Yelena signals to the Jaegerists to get ready to fire if needed, the rooftop cracks and Galliard's Jaw Titan appears in front of them. Yelena is at a loss for words as she notices several blimps from Marley arrive at their location. Yelena pleads with Eren to exit his Titan form and flee to safety underground. Eren ignores her and goes on to pursue the Warriors, and Yelena orders that the Jaegerists' forces be mobilized to protect him. As they watch the ensuing battle from the headquarters, Yelena is horrified to see the Warrior Titans slowly triumphing over Eren and is overjoyed when Zeke arrives to aid Paradis's forces. Yelena is thrilled by the sight of Zeke destroying the Marleyan airships and continues to watch the battle as the newly freed Scouts arrive on the roof to join the battle. As Jean ponders why Zeke is in Shiganshina, Yelena states that he must have defeated both Hange and Levi to reach them. After hearing Armin dismiss Conny's concerns and that they have to team up with the Jaegerists to help the plan succeed, Yelena gazes intensely at him only to smile and ask that they help Eren and Zeke.

Eren eventually makes contact with Zeke, allowing him to take full control of the Founding Titan and begin the Rumbling. Aghast at what is happening, Yelena inquires on the fate of Zeke as Eren prepares his assault on the outside world. The Titans created by Zeke begin swarming the military's headquarters.

As the other Volunteers panic, Yelena is left dumbfounded as to why Zeke is not controlling his Titans. After the Titans around the headquarters are killed, Floch arrives and arrests Yelena and the other volunteers. Because of Yelena's knowledge of Zeke's plan to euthanize the Eldians, she is sentenced to death. As Floch and Jean prepare to publicly execute her and Onyankopon, Yelena sullenly refuses to give any final words when offered. However, she, Onyankopon and Jean are kidnapped by the Cart Titan before her sentence can be carried out. They are then taken outside the district to Hange, Levi, and Magath. Jean reveals that he has decided to side with Marley. Yelena asks him why she was brought along, and Hange informs her that Magath requested she be brought to him. Later that night Magath tries to get Yelena to reveal where Eren will go first, pointing out that she was the one who would have given Eren knowledge of the mainland. Yelena refuses to help Magath, perplexing everyone at her refusal to disclose information which would help save her homeland, and Pieck reveals that Yelena is in fact Marleyan. Yelena begins trying to turn the Marleyans and the Eldians against each other, reminding them of the crimes they have committed against each other. She talks about how Reiner Braun broke the Wall causing many of the Eldians inside to die by being devoured by Titans, she then talks about how Annie killed many Scouts, afterwards she criticizes Armin and the way someone so sensible would recklessly destroy the Marleyan naval port using his Colossal Titan stolen from Bertholdt Hoover at Liberio. After a few more remarks and seeing that she is not convincing the group, she finally manages to strike a nerve with Jean by reminding him of Marco Bodt's death at the hands of Reiner and Annie, causing him to attack Reiner in a fit of rage.

The next day the group travels to Paradis' harbor but finds it overrun with Jaegerists.

As Hange and Magath are observing the harbor they discover that Eren's Titans have most likely already reached Marley. Enraged, Magath begins torturing Yelena for information about Eren's whereabouts, breaking her arm in the process. Terrified, Yelena agrees to tell Magath where Eren is if he lets her live. Afterwards, Onyankopon builds a makeshift sling for Yelena's arm. After waking up from her fever contracted as a result of her broken arm, Yelena reveals she had discussed the Global Allied Fleet's military capabilities with Eren. Rather than the fleet, what worried her was the flying boat research base at Fort Salta. Yelena suspects that will be Eren's next target, to destroy the flying boats that could potentially be a threat. In return for cooperating, she asks those present to admit that Zeke's euthanization plan was right, to which Hange agrees. Yelena is later evacuated to a lifeboat with the rest of the ship's inhabitants so that Falco can transform into the Jaw Titan. Three years later in year 857, Yelena helps Onyankopon to carry crates of baseballs and mits to give to refuge children after the events of the Rumbling. The sight of baseball brings back certain memories, and she sheds a tear.
