Eren had been noted to be quite charismatic and had a talent for delivering impassioned speeches, often unwittingly managing to persuade the mass of his listeners to sympathize with his point of view. He almost always wears a blank expression on his face, no matter how dire or stressful the situation may be. Eren is also capable of displaying very violent behavior in the defense of people he does not even know. He can very easily become caught up in the pleasure of torturing and his enemies.
