Manon also noted the diversity of the group's line-up, with Lara, Sophia, Daniela, and herself as the first Indian, Filipina, Latina, and Black artists respectively to be signed under Hybe.

[46] Described as Katseye's "fashion fairy godfather", creative director Humberto Leon states drawing inspiration from young Devon Aoki, early Milla Jovovich, and Shakira for the image and appearance of certain members of the group.
