Beast (/ˈbiːst/; Korean: 비스트; stylized as BEAST or B2ST) is a South Korean boy band, formed in 2009 by Cube Entertainment. The band consists of five members: Yoon Doo-joon, Yong Jun-hyung, Yang Yo-seob, Lee Gi-kwang, and Son Dong-woon. Jang Hyunseung officially departed from the group on April 19, 2016.
Beast has released two Korean full-length album, seven Korean mini-albums, one Japanese full-length and various singles. The group's debut release was in October 2009, when their first mini-album, Beast Is the B2ST, was made available. They then released their first full-length album, Fiction and Fact, in 2011, receiving their first triple crown on M.net's M! Countdown for their lead single Fiction. In the same year, Beast made their Japanese debut with the release of the single, Shock (Japanese Version).
The group gained attention for the lack of industry success previously experienced by its members, with media outlets referring to them as "a group of recycled material". However, the group has achieved significant commercial and critical accolades with time, winning the Bonsang award at the Seoul Music Awards in both 2011 and 2012. Beast won the Artist of the Year (Daesang) award at the Melon Music Awards and Album of the Year for Fiction and Fact at the Gaon Chart Awards for the second quarter of the year in 2011. "Fiction" also won a Daesang for "Song of the Year" at the 2011 KBS Music Festival. They repeated this feat in 2012 winning Artist of the Year at the Melon Music Awards.
