MONSTA X successfully completed their South American tour across four cities as part of the '2026 MONSTA X WORLD TOUR [THE X : NEXUS]', performing in Mexico City (4th), Monterey (6th), São Paulo, Brazil (9th), and Santiago, Chile (11th). This was their first South American tour in approximately seven years since 2019. The Mexico City concert sold out completely, demonstrating strong fan interest, with audiences spanning various age groups. Local MONBEBE (official fan club) members sang along to the group's songs in Korean, creating emotional moments throughout the performances. The members showcased solid live vocals, commanding stage presence, and diverse musical sides through both signature tracks and solo/unit stages. During the São Paulo concert, fans even sang the 'Do What I Want' intro in Portuguese. Mexican media outlet Proceso praised the group for delivering an energetic concert featuring perfectly synchronized choreography, stunning visual and audio elements, and continuous audience engagement. MONSTA X will continue their world tour with North American dates in October across 10 regions.
