Omega X, the "big monster rookie," has continued its all-time move on a unique scale even before its debut.

Omega X (Jaehan, Hwichan, Sebin, Hangyeom, Taedong, XEN, Jehyeon, KEVIN, Jeonghoon, Hyuk, Yechan) became the first rookie idol to decorate the large LED display inside and outside COEX with the pre-sale of their first mini-album "VAMOS" on the 9th.

Omega X contains symbols such as infinite love and hope in the last letter of the Greek alphabet, Omega (Ω), and "X" implies that it will realize various values together from the first meeting with fans to the last moment of achieving its dream.
