ATEEZ, who topped the US Billboard 200, makes a surprise transformation into special 'rock stars'

Digital IP entertainment company IPX (formerly LINE FRIENDS) has opened its third pop-up, "MIGHTEEZ Rock The Stage POP-UP," at K-POP SQUARE Hongdae, featuring "MIGHTEEZ," the character IP created in collaboration with the global sensation group ATEEZ. The pop-up, which showcases the characters' surprise transformation into "rock stars," saw its pre-registration slots sell out in just five minutes, proving their soaring popularity.

MIGHTEEZ is a character IP that reimagines the personalities and moods of ATEEZ members through IPX’s creative lens, with a backstory where the members themselves gifted each character unique superpowers. In this pop-up, both the rock-star-debuting MIGHTEEZ and ATEEZ—who recently topped the U.S. Billboard 200 with their 14th mini-album—transform into the brightest rock stars on stage through the "Rock The Stage" theme. The members personally participated in an exclusive photoshoot tailored to this concept. The concept images for each member, posted on the official Instagram, garnered over 5 million combined views, heightening anticipation for a universe where artists and characters seem to share the same stage.
