Yoo Yeong Jin, known professionally as E:psilon, is a South Korean singer, dancer, and former member of ALPHABAT (알파벳). He graduated from Global Cyber ​​University with an associate's degree in Broadcasting Entertainment. He is the older brother of TEEN TOP member Yoo Chang Hyun (known professionally as Ricky).

He made his debut in November 2013 (using the stage name E:psilon) as ALPHABAT's vocalist, main rapper and main dancer with their first single, "AB City". The group originally debuted in 2012 as a duo and under another agency, but both members decided to leave YUB Entertainment. One kept the group's concept, and it re-debuted as a 9-member idol group under Simtong Entertainment.

However, they went on hiatus for almost 4 years as the members began enlisting in the military, and the group could not find any stability, switching agencies 3 times before signing with APB Entertainment (APB엔터테인먼트).

He enlisted for his mandatory military service, and after being discharged, he never returned to the group and went to work at his family's restaurant. APB officially announced his departure from the group in July 2021.

He was supposed to re-debut as a member of VVS but was not chosen in the final lineup. It is unclear if he remains in the entertainment industry or not.
