[March 19, 2026] Digital IP entertainment company IPX (formerly LINE FRIENDS) has opened the second pop-up “MIGHTEZ Wonder Room POP-UP (MIGTEEZ)” of the character IP “MIGHTTEEZ (MIGHTTEEZ)” created with the major global group ATEEZ (ATEEZ) at K-POP SQUARE Hongdae. This pop-up pre-order ended in about 5 minutes, and it showed a clear presence as a character IP that has grown.

“Mighty's” is a character IP that reinterprets the individuality and mood of ATS members with IPX's creatives, and ATS members added something special by gifting each fairy with unique superpowers. In this pop-up, you can see how Mighty's grew from a baby to a superpower fairy. In particular, it embodies a scene where Baby Mighty's is born in a drawer in the attic, which is a hideout of Mighty's, and secret messages hidden by ATS members themselves all over the place provide an excellent sense of immersion in a deeper worldview.

The “Mighty's Wonder Room Pop-Up,” which runs until the 29th, is decorated as a space steeped in the superpower narrative, which is the core worldview of Mighty's. When you first enter the pop-up, visitors are greeted by the main photo zone, which is the door to the magic room with the Mighty's. All over the pop-up, there are awards and life records that allow you to immerse yourself in the Mighty's growth process. In addition, there is a Mighty's introduction video that can be heard by ATS members after wearing headphones, a behind-the-scenes portrait frame with ATS members, and a hand printing zone to encourage fans.

Products that will lead you to immerse yourself in the superpower worldview have also been prepared. “Mighty's Plush Key Ring,” where they are studying magical abilities, and “Baby Mighty's Plush,” where they practice flying, have been revealed. In particular, in the case of Baby Mighty's, unlike the previous Mighty's, the ears and wings were shown to be smaller, suggesting changes according to ability.

Also, in commemoration of the second pop-up, a fashion goods product with “COLER (COLER),” which allows you to experience practical and wearable products developed by IPX over a long period of time with various accessories, was also launched. As part of the COLLER KPOP lineup, Mighty's first fashion goods item was planned. In addition to the “crossbody bag” depicted on the Mighty's label, practical products such as the “card holder” are included to help with a spring makeover.

Recently, IPX has continued to expand the KPOP IP worldview and present continuous pop-ups that continue the story. In the case of Mighty's, it came back 5 months after the first pop-up held last October, and is creating a buzz along with ATS' active activities through continuous storytelling. Additionally, IPX successfully completed the second pop-up “SWEET Dreamiez POP-UP” of the character IP Dreamiez (Dreamies), which was created with NCT DREAM at K-POP Square Hongdae on the 15th, and LINE FRIENDS Square Myeongdong opened the third pop-up 'ZO&FRIENDS (ZO&FRIENDS LUCKY SHOP'), a character created by IPX and G-DRAGON together, to meet fans around the world.

An IPX official said, “This Mighty's Wonder Room pop-up, which came back after about 5 months, was designed so that people can gradually immerse themselves in the worldview through a story structure that gradually expands,” and “We plan to show a deeper worldview with each pop-up, and we plan to continue showcasing IPX's differentiated character IP culture to K-pop fandoms around the world.”

Meanwhile, “MIGHTEZ Wonder Room POP-UP” will be held sequentially at K-POP Square Hongdae and at Shinsegae Centum City in Busan, and this pop-up product can also be found online.
