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 his class. He acted with little intelligence, and responded to an attempt of communication by attempting to eat Hange. He appeared to have a very limited sense of pain, since he gave little reaction when his eye was gouged out by a spear. He exhibited a loss of activity after three hours of sunlight deprivation.

The Female Titan arc
Bean presumably appeared 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 were killed, but two were taken alive; Hange nicknamed them "Sonny" and "Bean". She performed a number of experiments on them including: testing their response to attempts at communication, injury, and sunlight deprivation. She had further tests planned; however, during the night, both test subjects were killed by a soldier. Armin later came to the conclusion that this was the doing of Annie Leonhart, as he believed 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, .
