History

2014–2015: No.Mercy and debut

The group was formed, as the result of the survival program called No.Mercy, which was launched by Starship Entertainment and Mnet in December 2014. Through the course of ten episodes, twelve trainees; thirteen after I.M joined in episode eight, competed against each other through various performances and were ranked from one to twelve, with one being the highest and twelve being the lowest. They also have to wear a nametag with their ranking, which changed following the challenges and performances set by the judges. For the show, the participants worked directly with artists from Starship Entertainment, including Hyolyn, K.Will, Mad Clown, and Soyou, as well as other artists such as Rhymer, San E, Giriboy, and Genius Nochang, who also served as judges in ranking the contestants. For the concluding mission, the nine remaining trainees formed into three groups of three to compete, while the members of Monsta X were selected from these nine in the final episode as the seven members of the group: Shownu, Wonho, Minhyuk, Kihyun, Hyungwon, Jooheon, and I.M.

No.Mercy also led to the 2014 spin-off web series Deokspatch, which also began airing in December, which was meant to showcase a more casual and lighthearted side to the competition in order for people to get to know the trainees better.
