Leonhart (Anime)

"Even if the entire world ends up hating you...just know that your dad is always on your side.... So promise me...that you'll come back...."

- Leonhart to his daughter, Annie

Leonhart (レオンハート) is the father and trainer of Annie Leonhart. He relentlessly trained Annie to fight, using mostly kicks and the attacker's weight against them. Memories of his pleas for forgiveness later create an opening for Annie to crystallize herself before Eren Jaeger has the chance to capture her.

Human form
Leonhart has a receding hairline with his black hair combed back. He appears to be a relatively short man, as his daughter is also very short, and well built for fighting as he is a trainer. He has only been seen wearing a light jacket over a white shirt with dark pants and shoes.

Pure Titan form
Leonhart's Pure Titan retained all of the features from its human form. Most notably it had a large, round nose and large eyes.

Personality
He seems to be a relentlessly strict trainer, not allowing his daughter to take breaks and yelling at her during the training sessions. However, sometime before Annie's departure, he has a change of heart and apologizes to her, asking her to promise him that she comes back someday, assuring her that he would always be on her side.

History
Many years ago, Leonhart was relocated to the Liberio internment zone from another country after it was discovered he had Eldian blood. While living in the city, he came across a baby girl who was abandoned for similar reasons; Leonhart decided to adopt the girl and gave her the name Annie. As Leonhart began raising Annie over the following years, he decided to have her become a Warrior so that he could improve his own life. Leonhart taught Annie fighting techniques that involved kicks and the use of the opponent's weight against themselves. Because of his harsh treatment, Annie eventually lashed out at him during training, crippling him for the rest of his life.

Before Annie left their hometown, Leonhart apologized to her, saying that it was too late to ask for forgiveness. However, Leonhart assured her that even if the whole world hated her and treated her like an enemy, he would always be by her side. He asked her only to promise him that she will return home.

Wall Sina, Goodbye: Part One
During her investigation of the disappearance of Carly Stratmann, Annie is reminded of her relationship with her father after seeing the relationship between Carly and her father Elliot G. Stratmann.

Assault on Stohess arc
While Annie is trying to escape from Stohess District transformed in her Titan form, she remembers the last words her father said to her before she left her hometown.

Marley arc
Leonhart attends Willy Tybur's production at the Liberio festival, being seated in reserved seats meant for honorary Marleyans. He speaks with Karina Braun about Bertholdt Hoover's father having passed away, and Mrs. Braun discusses the pride of both Annie and Bertholdt having devoted their lives for Marley. Leonhart denies this, adamantly stating that Annie is not dead, as she promised to come home.

Leonhart listens apathetically whilst Willy delivers his speech, seemingly caring little for his revelations on the true history of the Great Titan War, or his reasons to wage war on Paradis Island. After Willy officially declares war, the Attack Titan comes forth, killing Willy and sending building wreckage into the crowd.

War for Paradis arc
Along with all other Subjects of Ymir, Leonhart is spoken to by Eren Jaeger through the Founding Titan. Leonhart drops his shopping and falls to his knees, panicking about the declaration that the lives beyond Paradis Island will be exterminated.

Leonhart is among a group of Eldians who desperately try to convince Liberio's guards to allow them to leave before Eren arrives with the Wall Titans. Unfortunately, the guards do not believe the crowd, as only Eldians were able to see Eren's broadcast, and accuse the Eldians of plotting to escape their internment camps. The guards begin to detain the group and Leonhart, recalling Annie's promise to return to him, begins lashing out at them.

Leonhart, along with many of the other Eldians in Liberio, manages to escape the internment zone. Taking a Marleyan soldier and his family hostage, Leonhart forces him to operate a train and take all of the surviving Eldians to Fort Salta so that they can steal an airship and escape the Rumbling. As Fort Salta comes into sight, Leonhart is horrified to see airships already taking off, as well as the steam of the Rumbling on the horizon. Reaching Fort Salta, Leonhart and the others find that all of the fort's airships have departed to participate in the attack on the Founding Titan.

As they watch the ensuing battle, Karina collapses in tears for manipulating her son to join the Warrior program and Leonhart attempts to console her. As he is consoling her, the group is horrified to see Marley's airships being destroyed by the Beast Titan, who appears on top of Eren's Titan form. Leonhart reassures Karina by reminding her that her son is safe on Paradis, but is caught off-guard to see Reiner arriving with Paradis soldiers to stop Eren.

After the flying boat crashes, Leonhart is seen with some others helping to pull Onyankopon out. Though he is unconscious, Leonhart asks if he knows his daughter, Annie. After helping Onyankopon, Leonhart leads a group of Eldians to try to get medical aid for their wounded, but they are met with hostility from the Marleyans.

Leonhart tries to talk down his allies and reach a peaceful resolution, but hostilities continue to escalate. Marley's military commander Müller arrives and fires a pistol into the air, gaining both sides' attention. He convinces the Eldians and Marleyans to work together to defend the fort before helping Leonhart up. As the two men agree to work together, Leonhart is surprised by the sudden arrival of Annie. Before the two can properly reunite, however, a smoke is released into the fort which causes Leonhart and the other Eldians to transform into pure Titans. The Titans inside the fort all immediately rally to the source of all living matter to defend it as it tries to return to Eren Jaeger.

After Eren's death the power of the Titans is undone and all of the Eldians return to their human forms. Leonhart happily reunites with his daughter, but their reunion is cut short by the arrival of Marley soldiers. Müller demands that the Eldians prove that they can no longer turn into Titans or face execution. Leonhart suggests that they take a blood test of all the Eldians, but Müller insists that he will execute them all on the spot unless they provide immediate proof. The Eldians are only saved by the intervention of Armin Arlelt, who convinces Müller that they are no longer a threat.

Relationships

 * Annie Leonhart - At first he seemed to be a strict and not very approachable father for Annie, though for some reason he later changed his mind and demonstrated his love for his daughter by tearfully hugging her and assuring her that he would always be on her side. This reaction seemed to deeply surprise Annie, indicating that it was not common in him until then.

Trivia

 * While Leonhart was portrayed with dark blond hair in the first season of the Attack on Titan anime, his hair color was darkened considerably for his appearance in the Wall Sina, Goodbye OVA adaptations.
