PENTAGON (펜타곤) is a ten member boy band that will debut in 2016 under CUBE Entertainment.
On December 2015, Cube Entertainment announced that they are preparing to debut a boy group in mid-2016, 4 years after BTOB's debut. On April 26, 2016, Cube revealed its new boy-group, Pentagon, with the group trailer "Come Into The World".
The final line-up of Pentagon was decided through Mnet's reality-program, Pentagon Maker. Pentagon Maker aired online through Mnet's digital content brand, M2, and showcased the members challenging five aspects: Performance, Dance, Teamwork, Talent, and Mind. By the end of the show, Hui, Yeo One, Hongseok, Kino, Wooseok, Jinho and Yuto were confirmed as the official members of the group.
On July 9, Pentagon released the collaboration songs, "Young" (prod. by Dok2) and "Find Me" (prod. by Tiger JK). A music video for "Young" featuring members, Hui, Yeo One, Kino, Wooseok and Yuto, was also released.
The group was originally scheduled to host their debut concert on July 23, 2016 at Jamsil Indoor Stadium, but Cube Entertainment delayed the concert and debut date of the group because of some internal issues.
On September 30, Pentagon were confirmed to debut on October 10, 2016 with a self-titled mini album, that will include the title track "Gorilla". The group will also hold their debut showcase on the same day
