Annie Leonhardt (アニ・レオンハート Ani Reonhāto?), formerly a member of the 104th Trainees Squad who later enrolled in the Military Police Brigade after their graduation, is a Titan Shifter and a member of a mysterious organization keen on destroying the Walls for unknown reasons. She is voiced by Lauren Landa in the American English dub, who is well known for voicing Sister Lucia from A Certain Magical Index, Sailor Neptune from Sailor Moon series, Kasumi from Dead or Alive series, and Kyoko Sakura from Puella Magi Madoka Magica. Her appearance is similar to that of Sister Lucia because both she and Sister Lucia has a blonde hair and blue eyes.
Annie is considered a solitary, stoic type and friendships don't come easily. She is apathetic and somnolent with little desire to put in any effort into meaningless disciplines or activities, and instead focuses exclusively on making it into the Military Police to obtain an easy life. Yet, somehow she does seem to hold some strange fascination with people that hold a deep sense of duty and righteousness -- in those people who do care and who can devote their lives and even die for something.
Originally from the same village as Reiner Braun and Bertolt Hoover, Annie had rigorously trained with her father ever since she was young. During a flashback, her father begged for forgiveness, for the harsh way he trained her. Thinking it may be too late, he tells Annie to treat everyone as her enemy and she promises to come home to him. 
Graduating 4th, a rank below Bertholdt Fubar, Annie chose to enlist in the Military Police. When the Colossal Titan breached Trost District Annie was assigned to rear guard with Mikasa and a few of the others to help fend off the Titans as the people are evacuated to the safety of Wall Rose, which hadn't been breached yet. She was involved in helping Jean Kirschtein and the other retake the supply unit to restock the gas canisters for their gear. While watching the Rogue Titan fight off the other titans, Annie overhears Jean and Reiner arguing, and so she thinks that the Rogue Titan may be their ally. She later learns about Eren's titan shifting ability.
During hand-to-hand combat training, Annie easily bests Eren and Reiner with a kicking technique her father taught her. Later on, she watches Eren use the same technique to subdue Jean when he tried to pick a fight. The next day, Annie and Eren were watching him as he practice hand-to-hand combat. She noticed that Jean was only taking it seriously to pick a fight again and doesn't see anything positive from it. Annie points out something wrong in how Eren handled the kicking technique and offers to teach him the proper techniques. 
Soon the two titans captured for research are killed and the Military Police check the Three Dimensional Maneuver Gears from the trainees. During that time, Armin, Annie and Conny Springer discuss which military branch they want to join. When Annie reveals that she will go to the Military Police, Conny considers joining them too and asks for her opinion. Annie responds by telling him that it's his decision to make, not hers. When she learns that Armin planned to join the Survey Corps, she asks him what he would do if he was ordered to die. He tells her if the reasons were necessary, he would do so. Annie states that she thinks he's weak physically, yet very strong at heart. She showed Marco Bott's 3D Maneuver Gear for inspection as her own, and that prompted Armin to become suspicious of her. Ultimately during the Survey Corps draft, Annie leaves to join the military police.
Arc 2: Female Titan VS MikasaEdit
Annie awakens in her room in Stohess, the district on the east edge of Wall Sina. Annie is teased by Hitch and Marlo, but a member tells them to leave her alone believing that she hasn't recovered from battle and is the only one who has real combat experience. After the Military Police are given orders to follow Eren's escort to the Capital, Armin approaches her and asks for help in hiding Eren until they can convince the king to better protect the walls. Annie reluctantly agrees and escorts them to a place where they can hide. When Eren and Armin try to get her to go down an underground passageway with them, she refuses and suspects something is awry. Mikasa, having enough of Annie's games, takes off her hood and draws out her 3DMG. She refers to her as the Female Titan. Armin's suspicion is confirmed when she smiles in the same way as the Female Titan, and by her refusal to enter the passage, where she cannot transform. 
After firing a signal, disguised recon corps comes out of their hiding places and try to restrain Annie. Seeming captured, she is still able with a flick of her thumb to open a small blade hidden in her father's ring (that she put on after agreeing to help Armin) and cuts herself, transforming into her titan form which kills those restraining her. Now, resuming her attempts to capture Eren, Mikasa and Armin realise how desperate she is and try to get him to fight her. Overcoming his initial shock at the identity of the female titan, he transforms into his titan form and takes Annie on. 
As Eren tries to hold Annie off from escaping, Mikasa realizes that she may be the only one who can stop her. Knowing that she may try to climb the wall to escape she follows her and Eren as the fight. As predicted, Annie tries to escape over the wall. Mikasa cuts off all of Annie's titan fingers, causing Annie to fall. Eren in his titan form holds down the body as both the military police and the members of the Survey Corps, cut into the flesh and try to extract Annie. 
However, before they can get there, Annie uses her Harden Ability to create a crystal barrier around her before she's exposed from her Titan body to possibly either prevent her court-martial and execution or to avoid interrogation by the government altogether. Jean desperately tries to break the crystal to extract her only for his blades to break. Levi tells him "it's over" & Hanji tells both the Military Police & the Scouts to take her underground and detain her.
Currently, the reasons behind Annie's motivations for trying to kidnap Eren remain unknown. 
Annie is one of the strongest fighters alongside Mikasa and Eren. She was ranked as one of the top 5 trainees at 4th position, implying a degree of skill in other military combat forms such as the use of ODM Gear.
Like Eren, Annie displays an ability to transform into a 14 meter titan. She uses this form to wipe out military formations the Survey Corps during their attempt to retake Wall Maria. Annie's titan form is similar to Eren's form, except for being more feminine.
It is unknown how Annie seems to know the secrets of transforming into a titan and to be so adept in using her titan powers. She is far more experienced in using her titan form compared to Eren, who had only discovered his titan powers recently. She is probably the most skillful user of titan powers among all current known titan shifters, sporting a variety of presumably learned powers not exhibited by any other titan shifters.
In her titan form, she is able to selectively regenerate certain parts more quickly as opposed to automatic simultaneous regeneration of all the damaged parts. She can also selectively harden parts of her flesh to protect it from damage or to enhance attacks, and let out cries to attract attentions of regular titans, seemingly being able to deliver simple orders while she is at it. Unlike most titan shifters who tire to the point of collapsing, she is able to preserve stamina and is fit enough to utilize the 3DMG to kill experienced soldiers before transforming for the second time - something never seen done by any known titan shifters thus far.
Being trained as a child by her father, Annie has shown to be adept in various martial arts such as Muay Thai, being her primary form of stand up striking. One such move was a kicking technique that she used to defeat Eren and Reiner during training. She also has skill in Brazilian jiu-jitsu which she showed when defeating Eren in past spars and taught him various chokes and locks, which he would also apply effectively against Reiner. As such, she had proven herself to be the top hand-to-hand fighter among the recruits. This gives her a massive advantage in combat in her Titan form, as she combines her extensive hand-to-hand combat skills with the incredible abilities of her 14m Titan form.
