Sonny

"Sonny" is the name given by Zoë Hange to a Titan which is captured after the reconquest of Trost District.

Abilities
Sonny displays typical traits for a Titan of his class. He displays no intelligence. He does not appear to feel pain, ignoring a spear driven into his heart in favor of attempting to eat Hange. He loses activity after an hour of sunlight deprivation.

Hange describes his personality as "introverted", but this may just be projection on her part.

Story
Sonny first 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 unknown assailants.It is believed that Annie was one of the assailants.

Trivia

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