One Punch's Might

Reiner believed they needed to become soldiers and find a way to get close to the Interior Military Police, but Annie was very impatient with this, because it had taken them two years to gather even this limited intelligence. Annie was anxious and thought that since the King of the Walls was still bound by the "Vow Renouncing War," they should just destroy the rest of the walls. But Reiner thought they needed to proceed cautiously, so they joined the 104th Training Corps.

13-year-old Annie: Upon joining the Training Corps, Annie barely interacted with anyone. Reiner said Annie's aloof attitude was detrimental to their infiltration missions, and Jean also thought Annie had no friends and disliked communicating. Despite this, during a combat training session, Annie's praise of her fighting skills piqued Eren's interest, and Eren shared her views on combat training with him. That night, Eren imitated Annie's fighting techniques, knocking down Jean who had challenged him. In a later training session, Eren asked Annie how good his kicking skills were. Annie thought Eren's kicking was terrible and offered to teach Eren combat techniques, but Eren decisively refused. However, in Eren's later flashback, Annie did indeed teach him combat techniques. During one of these lessons, Annie was provoked by Eren, and Annie assumed Mikasa fighting stance. Just as Mikasa approached Annie, about to begin the fight, the flashback abruptly ended...

During his three years with the Training Corps in "Mew Showdown," Annie frequently infiltrated other locations to gather intelligence. During one mission to track Kenny, Annie was captured by Kenny, but Annie to escape using quick Kenny. One evening, in a private conversation with Reiner and Bertolt, Annie expressed that he had reached his limit and wanted to return to Marley with the intelligence he had gathered. Reiner believed that returning to Marley with these findings would be a huge disappointment, and decided to continue destroying Wall Rose to find an opportunity, setting the date for the operation as the day after the Training Corps' disbandment ceremony. Annie paused for a moment and warned Reiner, "Many of your friends will die because of this, maybe all of them." Reiner denied that they were friends. Annie was disgusted by Reiner's words, and Reiner apologized for placing the burden on Annie, then ended the meeting.

Appearance and Clothing: Annie Leonard has fair skin, golden hair, blue eyes, a high nose bridge, and always wears a white sweatshirt.

She is petite but very strong. In her daily life, she always wears her hair up, which makes her look energetic and capable.

She is taciturn and has a somewhat unapproachable air. Perhaps she deliberately avoids contact with others, so Annie rarely speaks. In battle, she prefers to act independently and go it alone.

I deeply respect those who resist the tide of society, I abhor unfair treatment, and I want the weak who have been assimilated by the tide of society to be recognized as human beings and to receive equal treatment.

Annie was abandoned by her biological parents shortly after birth because a blood test revealed her mother's affair with Eldians. She was adopted by an Eldian man in the Liberio Internment Zone, who became her foster father. To improve his life, her father had Annie learn his martial arts from a young age, hoping Annie would become a Marley warrior. At that time, to her father, Annie's value lay solely in becoming a warrior. Later, Annie successfully became a warrior candidate. One day after training, Bertolt, also a candidate, casually struck up a conversation with Annie, but Annie didn't notice the conversation between Reiner and Bertolt. After stepping on a bug on the ground, she hurriedly left.

Annie was a warrior candidate, soon became a Marley warrior without a doubt, inheriting the Female Titan (the Marleyan military believed that the Female Titan, with its Hardening, would greatly enhance Annie's fighting skills). She was about to travel to Paradis Island with Marcel, Reiner, and Bertolt to complete the "Founding Titan Recovery Plan." On the morning of their departure for Paradis Island, her father suddenly knelt down before Annie, weeping and apologizing. He didn't beg for Annie's forgiveness, but only pleaded with Annie to promise him that she would return. He told Annie, "Even if the whole world becomes your enemy, even if the whole world hates you... Dad will always be on your side." Annie then promised her father.

On the night Annie's Female Titan arrived on Paradis Island, Captain Marcel was eaten by the Pure Titans (Ymir) while trying to save Reiner. A panicked Reiner immediately fled, and Annie and Bertolt foolishly followed suit. As a result, they lost their captain and the Jaw Titan before the mission had even begun. Annie believed the mission was a failure due to the loss of Marcel and proposed returning to Marley after finding the Titan who ate Marcel. However, Reiner, not wanting to disappoint his mother who had high hopes for him, vehemently opposed ending the mission.

Annie retorted that Reiner couldn't go back because he would be stripped of his warrior status for causing Marcel's consumption. Reiner, however, used this to his advantage, binding Annie and Bertolt to himself, as they too had escaped and were likely to be punished. He argued that only by retrieving the Founding Titan could they return home. Enraged by Reiner's selfish words, Annie immediately beat Reiner, angrily accusing Marley and Eldia of being liars and only thinking of themselves. Exhausted, Annie turned to leave, only to be subdued by the now-standing Reiner coerced Annie into continuing the mission. Ultimately, Annie chose to obey.

After the four warriors Annie transformed into the Female Titan and led Reiner and Bertolt towards the wall. Along the way, she used the Female Titan's abilities to attract a large number of Pure Titans. Since there was no Jaw Titan to relieve them, Annie had to complete the distance that would normally be covered by the Jaw Titan and the Female Titan together. Upon reaching the wall, Annie was exhausted and fell into a deep sleep. Later Bertolt and Reiner destroyed the wall. When Annie awoke, she was in a refugee camp at Wall Rose with Reiner and Bertolt, while Eren, Mikasa, and Armin were nearby.

On the evening of the disbandment ceremony, Annie graduated fourth in her class from the training corps. During dinner, Jean said that everyone wanted to become military police because they wanted to live a comfortable life in the interior. Annie said that her own ambition was also to Military Police Brigade, but she didn't want others to think that she and Jean were on the same path.

The day after the disbandment ceremony of the Trost District siege, Bertolt suddenly appeared in his Colossal Titan form, destroying the gates of Trost District. Countless Titans entered the city, and Annie and the other trainees were thrown into battle. During this time, Annie, Reiner, Bertolt acted flexibly according to the situation. The trainees' gas was quickly depleted during the siege, but the supply depot was surrounded by Titans, leaving Annie and her classmates in a predicament without supplies. But then, a "Abnormal Titans" that only attacked Titans suddenly appeared. Armin, in a moment of quick thinking, lured the "Abnormal Titans" to the supply depot to attack the Titans outside.

Then, Annie and her classmates seized the opportunity to use their last bit of gas to rush into the supply depot, where they defeated the Titan in the basement and saved Connie's life. When they came out, they found the "Abnormal Titans" Titan that only attacked Titans had collapsed from exhaustion, and then Eren, who should have been eaten by the Titan, appeared in the back of the "Abnormal Titans" Titan's neck... Reiner, Bertolt, and Annie were shocked; their investigation over the past five years had finally made progress.

Eren then transformed into a Titan again and lifted a boulder to block the breach in Wall Rose. Just as Reiner and Bertolt were discussing their next move, Marco happened to overhear their conversation. Sensing something was wrong, Marco immediately made an excuse to leave, but Reiner caught up with him and subdued him.

Just then, Annie arrived. Reiner ordered Annie to dismantle Marco's Omni-Directional Mobility Gear, using Annie's father from her hometown as leverage. Despite her extreme reluctance, Annie painfully removed Marco's equipment. Reiner, Bertolt, and Annie quickly left, and then Marco was eaten by the Titan behind him. Seeing the gruesome sight of Marco being devoured, Annie shed tears. After Eren transformed into a Titan to plug the gap, Annie and the others cleaned up the battlefield, apologizing to the corpse that appeared to be her roommate Mina.
