Since debut, they had been known for their aggressive style, combining elements of hip hop, EDM and pop. This aggressive style with "tracks centred around loud, clattering, electronic instrumentals, vicious rap verses, and striking vocals" had also been influential across the fourth generation of K-pop, along with breaking gender norms before it was a trend. Additionally, they also obtained the modifier of "Next Generation Beast Idol".

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 the competition on episode 8) competed against each other through various performances and were ranked from one to twelve, with one being the best and twelve being the worst. 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. These artists also served as judges for ranking the contestants. For its concluding mission, the nine remaining members formed into three groups of three to compete and 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. It also continued as Deokspatch X on May 14, 2015, and as Deokspatch X² on October 2, 2015. These seasons focused on the newly formed Monsta X participating in variety show activities.

The group's name "Monsta X" contains the double meaning of "Monsters conquering the K-pop scene" and "My star" (Mon means "My" in French), then X symbolizes an unknown existence. Their fandom name "Monbebe" is also French for "my baby". Jooheon, Hyungwon, and I.M also released their song "Interstellar", which was produced for the final mission by Yella Diamond on February 12, 2015.

Monsta X made their debut with the release of their first extended play Trespass on May 14, 2015. "Trespass" is produced by Rhymer and described as a "strong and edgy track that reflects Monsta X's unique character". Trespass includes seven different tracks. Jooheon was the most involved member in the production of the mini-album and composed several songs, including "One Love", "Steal Your Heart", and "Blue Moon". I.M was also involved in the rap making of several songs. Kihyun and Wonho contributed song lyrics for the EP.

On September 1, the group returned with their second extended play titled Rush. The title track of the same name is described as a song that represents their signature style, that produced by Giriboy. Keone Madrid choreographed the dance and Joo Hee-sun directed the music video. The mini-album contains six tracks produced by Mad Clown, Crybaby and Rhymer. Jooheon also took part in making the rap for five out of the six tracks, while fellow member I.M was involved in four songs, including the title track "Rush". In 2015, they made their first U.S. appearance performing at KCON 2015 in Los Angeles. They also received the "Next Generation Asian Artist" award at 2015 Mnet Asian Music Awards and the "1theK Performance Award" at 2015 Melon Music Awards.
