MONSTA X successfully completed their South American tour as part of the 2026 World Tour 'THE X: NEXUS'. The group held performances in Mexico City (December 4), Monterrey (December 6), São Paulo, Brazil (December 9), and Santiago, Chile (December 11). This was their first South American tour in approximately 7 years since their 2019 'WE ARE HERE' world tour. The Mexico City concert sold out completely, and venues were filled with local fans of various ages, demonstrating the group's strong ticket power. During the performances, MONSTA X showcased their solid live vocals and distinctive choreography, presenting their hit songs along with solo and unit stages. Notably, their fanbase MONBEBE enthusiastically sang along to every song in Korean, and during the São Paulo concert, fans impressively chanted the introduction of 'Do What I Want' in Portuguese, creating a moment where music transcended language barriers. MONSTA X expressed their gratitude, calling it an 'unforgettable tour' and stating they were deeply moved by fans singing in Korean.
