Eren Yeager is a Scout Regiment Solider. He is able to control and turn into a titan. Eren has to physically harm himself in order to transform into his Titan form. In this form, he was a 15-meter-tall Titan, with shoulder-length black hair, pointed ears, a long nose, and a gaping, skeleton-like maw lacking lips. Unlike most other Titans, Eren's Titan form was considerably more muscular and defined; making him much stronger than even similar-sized Titans. He can control the form well.
