Petra Ral

Petra Ral (ペトラ・ラル) was a hand-picked soldier from the Survey Corps by Levi in the Special Operations Squad.

Personality
She looks up to Levi as a captain and cares strongly for her team, though notably at odds with Oluo.

Petra is kind and caring, as shown when she looks after and guides Eren when he is first admitted to the squad. She seems to have acted as some sort of attachment figure for Eren among Levi's Squad as she is the one shown to worry most about him. Although the whole of Levi's squad wished (and demanded, to an extent) Eren's unconditional trust, it was ultimately Petra who had lead him to do so.

She also showed the most remorse over the reaction of Eren's accidental transformation. Along with her comrades, she had bit her hand just like Eren, signifying that they had established a close bond.

Story
Petra is first introduced during an expedition outside Wall Rose, tending to a mortally wounded soldier. When she was unable to stop the bleeding, she helped Levi comfort the dying youth and wept openly at his death.

She is later selected to become a member of the Special Operations Squad and ordered to guard Eren Yeager. It is established that she greatly admires Levi, and argues frequently with Oluo Bozado over his imitation of their commander and his harsh behavior.

While initially wary of Eren and quick to draw her swords when he transformed by accident, she readily accepts him afterwards. She is the first of the group to bite her hand in imitation of Eren's method of transforming, and notes that doing so is actually quite painful. She serves as a gentle, almost maternal presence within the squad and discusses with Eren the importance of trusting one's comrades completely.

When the Female Titan begins her attack on the 57th Expedition, Petra is one of those most vocal about Eren avoiding battle. She repeatedly begs him to trust in his commanders and comrades, and accept the sacrifices of others so that the mission can continue. Eren eventually makes the decision to follow her advice, allowing the Survey Corps to successfully capture the Female Titan in a trap. Afterwards, the Special Operations Squad is ordered to standby while efforts are made to capture the human within the Female Titan. However, the operation ends in failure when the Female Titan uses a scream to summon other Titans to her position and is devoured by them.

Afterwards, the squad begins to retreat back to their horses, when a flare leads them off-course. They are then ambushed by a person later revealed to be Annie Leonhart, who murders Gunther Schultz before transforming back into her Titan form. Eren is ordered to flee while the surviving squad members engage the Titan in battle. Petra and the others initially seem to have the upper hand, first blinding the Female Titan before crippling both her arms. But when Petra and Eld Jinn move in for the kill, the Titan suddenly regenerates a single eye and kills Eld.

Death
Paralyzed from the shock, and despite Oluo's pleas, Petra is unable to react in time to the Female Titan's attack, which breaks her spine and splatters her against a tree. In the anime when the Survey Corps is returning home from the expedition, the surviving soldiers are being chased by Titans and in order to escape, Levi orders the troops to abandon the bodies of the deceased so that the weight would be lifted off from the wagons. One of the bodies that were disposed of was Petra's, whom Levi was watching over.

Her father comes to greet her when the troops return, briefly stopping to speak with Levi about his daughter. He reveals that she wrote to him constantly, and that she had great pride in being selected as a member of the Special Operations Squad. The contents of her letters suggest she may have had feelings for her commander, and this leads her father to express that his daughter is still too young for a serious relationship. Levi remains silent throughout the conversation and it's not shown when Mr. Ral was informed about his daughter's death.

Abilities
She was a skilled and experienced warrior and had a high kill record of Titan kills (58 Titan killed, 48 in team and 10 in solo), being the highest known in the series so far.

Relationships

 * Levi: Petra expresses great admiration for her commanding officer, and criticizes Oluo for imitating him. She notes that many people are surprised upon actually meeting him, and admits that he doesn't live up to the legend of Humanity's Strongest due to his many personality quirks and flaws. After her death, it is revealed that she wrote about him to her father and declared her intention to devote her life to him. The phrasing of her letters implies she may have had romantic feelings for him, and her father seeks out Levi to express his disapproval due to her young age.


 * Eren Yeager: Initially, she is uneasy around him and draws her swords on him when he accidentally transforms. However, after learning that it was a mistake she apologizes for her behavior and bites her own hand to acknowledge him as a comrade. She quickly takes him under her wing, and acts as an almost maternal figure during his month with the Special Operations Squad. During the mission in the forest, she repeatedly asks him to place his trust completely in his comrades and wishes for him to believe in her.


 * Oluo Bozado: They have an antagonistic relationship, often bickering with each other. She is highly critical of his attempts to imitate Levi, demanding that he stop and stating he should bite his tongue off and die. However, beneath this seeming-hostility is a strong bond of trust, born from their many missions together. His horror after her death, and attempts to mimic the man she idealized, have led to speculation that he may have had feelings for her.


 * Eld Jinn and Gunther Schultz: As comrades, she has great faith in them and cares deeply for them. She is enraged after Gunther is murdered, and repeatedly challenges the Female Titan while swearing revenge. Eld's death similarly shakes her, causing her to panic and leading to her death.

Trivia
