Eren Jaeger Biting Hand
Author Hajime Isayama created Eren to be "an ordinary youngster who gets paralyzed with fear when he sees a titan" rather than a stereotypical hotheaded protagonist often seen in shonen manga. He also stated that Eren's wish to go outside the city's walls is similar to his own when he was a child: He lived in a rural Japanese town surrounded by mountains. One day, he wanted to go beyond the mountains, which reflected in the town surrounded by walls in the manga where Eren lived in the series' beginning. The character's Titan form's physique was modeled after middleweight mixed martial artist Yushin Okami. Japanese actor Yūki Kaji commented on how it was important that he should voice Eren's Titan form because he believes it is an extension of the character. He had a meal with Isayama after he visited the recording studio and the manga artist told him he found Eren quite a difficult character but complimented Kaji by saying "You know Eren already", which gave him confidence. Eren's characterization was briefly altered for the English dub of the series making him self-reflective and eloquent in some scenes.
