Bean was a Titan that stood 7 meters high and had short messy brown hair and brown eyes. Bean also had light peachy-colored skin like the other normal Titans.
Bean displayed typical traits for a Titan of its class. It acted with little intelligence, and responded to an attempt of communication by attempting to eat Hange. It appeared to have a sense of pain, since it reacted when its eye was gouged out by a spear. It exhibited a loss of activity after three hours of sunlight deprivation.
