Eren Jaeger is the son of Doctor Grisha Jaeger and Carla Jaeger. Still a teenager, he tends to act according to his age, in impulsive, emotion-driven ways. He is also a titan-shifter, a power he somewhat despises, but is willing to use for humanity's sake. He is currently a soldier on the Survey Corps, under the direct command of Levi Ackerman. Overall, Eren is friendly, despite souding a little uninterested from time to time. He is, however, a hot-headed person, being easy to get on his nerves.
