Bean

"Bean" is the name given by Hanji Zoe to a Titan which is captured after the reconquest of Trost District.

Abilities
Bean displays typical traits for a Titan of his class. He displays no intelligence, responding to attempts to communicate by attempting to eat Hanji. 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.

Story
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; Hanji nicknames them "Sawney" and "Bean". She performs a number of experiments on them, testing their response to attempts at communication, injury, and sunlight deprivation. Further tests planned by her; however, during the night, Sawney and Bean are killed by a fellow soldier who were seen by the Guards to have escaped on their 3D Gear. Annie Leonhart was revealed as the killer later in the manga.

Trivia

 * Hanji's nicknames for the two titans, Sawney and Bean, are direct references to the famous cannibal of the same name,  Sawney Bean.
