Cyan Sung-Sun is the 56th Arrancar in Sōsuke Aizen's army and one of Tier Harribel's three Fracción, collectively known as the Tres Bestias. Her composed demeanor and snake-like abilities make her a unique presence among the Arrancar, often serving as a voice of reason within her group.

Personality and Appearance

Credits: Studio Pierrot

Sung-Sun is a slender female Arrancar with long, flowing olive-green hair, long eyelashes, and lavender eyes. She has three pink dots below her right eye and mask remnants that form hair clip-like extensions. Her outfit consists of a long white dress with long sleeves that extend past her hands, and she often covers her mouth with one of these sleeves.

Personality-wise, Sung-Sun is the most composed, mature, and intelligent of the Tres Bestias. She often advises her fellow Fracción to stop arguing, noting it makes them appear weak. Sung-Sun has a somewhat snobbish attitude towards her teammates and easily riles them up with taunts and dismissive gestures.
