[1] A music video directed by Karena Evans was released alongside the song itself, and stars Chlöe as the head of a sorority full of gorgons who seduce men in order to turn them into stone.

Prior to releasing "Have Mercy", Chlöe found fame performing alongside her sister as part of the R&B duo Chloe x Halle.

In 2021, the two embarked on solo careers, with Halle starring in the 2023 film The Little Mermaid, and Chlöe releasing covers of popular songs on social media.

[14] Margaret Farrell of Flood wrote that the song, which she called "seductive" and "confident", is "beaming with sexual autonomy and next-level bravado" and "overflowing with nods to her mentor Mrs. Beyoncé Giselle Knowles-Carter".

Largely inspired by 1990s teen films, it stars Chlöe as the head of a sorority house full of undercover gorgons who seduce a group of fraternity brothers and turn them into stone.

[24] Bianca Betancourt of Harper's Bazaar wrote that the video for "Have Mercy" proved that Chlöe was "Beyoncé's ultimate protégé", calling the choreography "high-power" and "sultry" and the outfits "standout ensembles".

[21] NPR's Ann Powers described the video's premise as "a sweet flip of horrifically common frat party #metoo narratives" and added that Chlöe's dancing "might cause Normani to sweat".

Chlöe's debut performance of "Have Mercy" took place at the 2021 MTV Video Music Awards in September 2021, where she was introduced by her sister Halle Bailey.

[30][31] During the performance, she energetically danced and twerked in a hot pink leotard and ankle boots, accompanied by male backup dancers in varsity jackets, while the song's lyrics flashed on the screen behind her.

[35] Billboard's Heran Mamo ranked the performance the second-best of the night, writing that Chlöe "made her mark on the VMAs stage" and called the choreography "tectonic plate-shifting".

[37] Vulture's Charu Sinha called her vocals "flawless" and the choreography "complicated", writing that she "commanded the VMAs stage with such obvious star power that it kind of rendered the night's other performances embarrassing by comparison".
