TWICE is arguably Asia's most in-demand female act, and it’s easy to get a sense of their domination from sales stats on Twitter, videos of airport mobs on Instagram and fancams that collect millions of views. The nine-member girl group have taken over their home base in South Korea with eight consecutive number one singles, boast chart-topping success in Japan, China, and and even America. And after performing as headliners at KCON 2018 Los Angeles — the world's largest K-pop festival and convention that brought out a reported 94,000 fans on August 11 and 12 — it was more than clear that Jihyo, Nayeon, Jeongyeon, Sana, Momo, Mina, Dahyun, Chaeyoung, and Tzuyu are primed to take on an entire arena stateside, too.

Before the full group appeared for their set, Jihyo, Momo, and Tzuyu delivered a cover of Beyoncé's "End of Time" — a song the trio is performing on their TWICELAND ZONE 2 Fantasy Park tour that currently only has dates in in Korea, Japan, and Southeast Asia. Wearing flapper-esque dresses, Jihyo nailed a slew of impressive ad-libs and Momo slayed a chest bump-heavy dance break to mark a moment American fans though they might only ever see live if they flew halfway across the world. Later in the night, Jihyo and Mina went into the crowd to introduce fellow performers Wanna One, earning meme-ready reactions from standing next to fans on the verge of tears.

By the time the full group hit the stage, TWICE fans — affectionately known as ONCE, get it? — were treated to the full-stan experience as they delivered recent hits like "Dance the Night Away," "What Is Love?" and "Likey" complete with the group's precise-yet-fun-to-follow choreography and adorable plays to the camera that overseas supporters usually only experience through YouTube. Momo, Dahyun, and Sana seemed to earn the biggest cheers from the SoCal crowd, with the latter member's famously adorable "Shy Shy Shy" lyric in "Cheer Up" earning an eruption of screams from the arena. It was a mini-trip to TWICELAND, but it was just long enough for ONCE and K-pop fans to get a visible sense of the superstars that make up the continuously growing phenomenon.

Less than an hour before hitting the stage, the ladies appear more than used to the chaos of lights being taken down and cameras shuffling through press junket–style interviews backstage at the Staples Center. Instead of allowing themselves to be distracted, the group makes direct eye contact, and cracks each other up when they look around to see who will answer a tougher question. That same personable energy seeped into the KCON crowd to earn TWICE the type of screams most expect to hear for America's biggest pop sensations and act as a thunderingly audible reminder to why TWICE is one of K-pop's global leaders.

Teen Vogue: TWICE was last in Los Angeles in August 2016 when your careers were just starting to take off with 2016's "Cheer Up," which went on to be Korea's most-downloaded song of the year. Take us through what's changed.
