"DANCERACHA" is an adaptation of "3RACHA" for the dance team. They were just called the dance line, until they started calling themselves DANCERACHA.[2]
On August 26, 2018, DANCERACHA made an unofficial debut with the music video called "Lee Know X Hyunjin X Felix" as part of the SKZ-PLAYER series, showcasing the unit's dancing and choreographing skills.
They performed "Wow", their first song as a unit, on November 23, 2019 during the Seoul concert of their first world tour, "District 9 : Unlock". Since the repackage album IN LIFE including the song, they occasionally release songs as an unit.
In September 2021, they were selected as the face of ETRO's "EARTHBEAT" campaign. They visited the brand's Paisley Capsule Collection pop-up store in Seoul in April 2022.
