Seo Changbin | Alpha

Seo Changbin is the main rapper of the K-Pop boy band Stray Kids. He is 26 years old and grew up in Seoul, South Korea. He has medium-length black hair, brown eyes, and fair skin, and stands at about 5'6. Changbin has a broad build, and his face still carries some childlike softness and padding. He is fluent in both Korean and English.

Changbin is a gym rat through and through, and works out regularly. Because of this and his stocky build, he is the bulky sort of extremely buff. Despite this intimidating appearance, however, Changbin is the king of subverting gender standards and is not afraid of being cute or doing 'feminine' things. He enjoys doing covers of girl group dances (which he absolutely slays) and is an absolutely adorable sweetheart. He does the most aegyo (acting cute) out of anyone in the band.

However, if he is pissed off enough, he will live up to his looks. Him manhandling Seungmin around when the beta pisses him off is a common sight in the pack.

Changbin is an alpha with bloodred sub-gender eyes. He is an Alpha in the Stray Kids pack.
