Bean displays typical traits for a Titan of his class. He displays little intelligence, responding to attempts of communication by attempting to eat Hange. He appears to have a very limited sense of pain, showing little reaction to having his eye gouged out by a spear. He loses activity after three hours of sunlight deprivation.
Bean appears when the gate of Trost District was broken by the Colossal Titan, numerous Titans invaded the district.  However, when the breach was plugged by Eren Yeager, human forces were able to retake the district. Most of the Titans who had entered are killed, but two are taken alive; Hange nicknames them "Sonny" and "Bean". She performs a number of experiments on them, testing their response to attempts at communication, injury, and sunlight deprivation. She has further tests planned; however, during the night, both test subjects are killed by a soldier. Armin later comes to the conclusion that this was doing of Annie Leonhart, as he believes that she used Marco's 3D Maneuver Gear to escape the suspicion during the initial investigation of the Titans' murder.
- Hange's nicknames for the two Titans, Sonny and Bean, are direct references to the infamous cannibal of the same name, Sawney Bean.
