Bean

"Bean" (ビーン) was the name given by Hange Zoë to a Titan which was captured after the reconquest of Trost District.

Abilities
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 very limited sense of pain, since it gave little reaction when its eye was gouged out by a spear. It exhibited a loss of activity after three hours of sunlight deprivation. It is constantly high.

The Female Titan arc
Bean presumably appears when the gate of Trost District is broken by the Colossal Titan, and numerous Titans invade the district. However, once the breach is plugged by Eren Yeager, human forces are 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 performes a number of experiments on them including: 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 the doing of Annie Leonhart, as he believes that she used Marco's 3D Maneuver Gear to escape suspicion during the initial investigation of the Titans' murder.

Trivia

 * Hange's nicknames for the two Titans, Sonny and Bean, are direct references to the infamous cannibal of the same name, .
