On January 3 airing of 'Mask King,' Tell Them I'm Dragon King was unfortunately eliminated while competing in the second round where he performed a cover of "Moon Of Seoul" originally sung by Kim Gun�Mo. The contestant was then asked to take off his mask as part of protocol of the show, revealing his identity.

Tell Them I'm Dragon King was none other than MONSTA X's vocalist Kihyun, who has garnered much attention with his collaboration track with Soyu and Giriboy as well as various other OST tracks for recent dramas that aired.�

During the interview, Kihyun said to Kim Gu Ra, "When senior B.A.P's Daehyun came out, you said something along the lines of, 'You know those groups who recently debuted like BTS and Monster, those kinds.' So I wanted to come out and tell you that our group name is MONSTA X not Monster."
