Attack on Titan Season 3

After recovering Eren and Historia, the recruits are put under the care of Levi. Stuck out in the middle of nowhere, Hange subjects Eren to a series of experiments in an attempt to find out more about his ability. But when their link to the secrets behind the wall is murdered, the squad must move out and find a new refuge. Except, a figure from Levi’s past has his own plans to stop them.

 Eren is Shingeki no Kyojin's protagonist. His adoptive sister, Mikasa, notes on numerous occasions that he acts on impulse without thinking things through, and she often pulls/carries/throws him when he starts fighting with others to protect him from himself. Along with Mikasa, he tends to spend his free time with their mutual friend, Armin.  His father is a doctor (whom is well respected by Hannes and potentially many more) whilst his mother is a housewife. When Eren was a child, he saved Mikasa from being sold off when a visit to her home with his father. Three men—killers of her parents—were in her house, and he killed two of them—one by slitting his throat and the other by charging at with a quickly assembled spear. Mikasa herself killed the third man after Eren urged her to fight whilst the man strangled Eren. After this, he gave Mikasa his scarf and Eren's father adopted Mikasa into their family. Later, when the Colossal Titan broke through Wall Maria the debris from this attack scattered and hurtled towards his home. He could only watch on as his mother—trapped under the rubble of their house—was eaten by a titan. This event lit the fire of revenge within Eren that he would kill every giant and not live a life cowering in fear.  Sometime after this—before the time skip that jumped a few years ahead, to when he became a soldier—his father injected him with something. It's unknown what at this time but it turns out, because of the injection, Eren can utilize the ability to transform into a titan himself (which explains how his limbs were able to regenerate) with side effects of a high fever and massive stamina drain.  Eren has a special titan power called the "Co-ordinates", by which he can direct abnormal titans to attack elsewhere. Note: Eren Yeager is the official English translation by Kodansha.

Eren Yeager

Age: 15 Birthday: November 3 Height: 163 cm (5'4") Weight: 55 kg (121 lbs) Position: 104th Trainees Squad, Scouting Legion Graduation Rank: Outside the top 10  Eren's best friend, he is physically weak yet emotionally strong. Even though lacking in actual combat, Armin is a genius on theoretical courses and can make plans even under extreme pressure. Even so, Armin kept on thinking that he is weak. He himself does not notice the things he does for Eren and Mikasa, and believes himself to be completely incompetent and hates himself for having to rely of Eren and Mikasa.

Armin Arlert

Age: 15 Birthdate: February 10 Height: 170 cm (5'7") Weight: 68 kg (150 lbs) Position: 104th Trainees Squad, Scouting Legion Graduation rank: 1st  Mikasa is Eren's adoptive sister and mutual childhood friend of Armin. Mikasa shares an unbreakable bond with Eren following events in their past, and rushes to protect him whenever he is in danger. Mikasa possesses impressive fighting skill and strength even as a child.  As a teen, Mikasa is considered a genius among all the army trainees and is incredibly skilled at combat and agility. She constantly worries for Eren's well-being and lives to protect him.  When Mikasa was younger, her parents were murdered and she was taken hostage to be sold into slavery. Eren managed to find her and killed two of the three kidnappers by catching them off guard, despite only being a child. The third kidnapper discovered the scene and began strangling Eren while holding him in the air. Mikasa, trembling, grabbed Eren's knife from the floor. In that split second, Mikasa came to terms with the cruelty of the world, gaining perfect control of her own body and using that strength to kill the kidnapper in a single strike through the heart—killing him to save Eren.  In the aftermath of this trauma, Mikasa asked Dr. Jeager where she could possibly go from here. She was cold and had no place left to call home. Eren gave Mikasa his red scarf and Dr. Jeager welcomed her into their family. Because of Eren's heroics and this gesture, she feels she owes her life to the Jeagers. She continues to wear Eren's scarf from that day into adulthood, and they are inseparable.

Flegel Reeves

Age: Unknown Birthday: September 5 Height: 170 cm (5'7") Weight: 60 kg (132 lbs) Affiliations: Scouting Legion  Scouting Legion's Squad Leader.  Hange is very passionate and driven in pursuit of new knowledge. She can be seen as very hyperactive, often diving into projects without thought for personal safety (and frightening lots of subordinates in the process), instead preoccupied with observing and documenting the subjects. Some misunderstand these acts and Hange is seen as eccentric and having more than a few screws loose. She also enjoys discussing this research, but as the lectures can be very long and detail-oriented, not many fellow soldiers find them interesting.  Hange is often excited by Titans and is always eager to experiment with them, coming off as extremely emotional regarding titans. For example, she cried at the amount of pain being caused to a Titan during experimentation.
