『Eren Yeager』

Age: 15

19 (After Time Skip)When Eren was a child, he saved Mikasa from being sold off when on 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 took 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 all titans and not live a life cowering in fear.After the fall of Shiganshina at an unknown time, Grisha Yeager injected Eren with the titan serum which turned him into a pure titan, Grisha then allowed Eren to eat him so that Eren could inherit the Founding and Attack titan.
