On June 24, 2021, a vignette aired promoting Davenport's arrival to WWE's NXT UK brand. Davenport would score a winning streak upon her debut over several opponents such as Xia Brookside, Nina Samuels, Emilia McKenzie and many more until she seized an opportunity to challenge Meiko Satomura for the NXT UK Women's Championship. On the January 6, 2022 episode of NXT UK, Davenport failed to capture the title from Satomura, marking her first loss in NXT UK. On the August 23 episode of NXT 2.0, Davenport made her in-ring debut in the brand and collected her first loss over Indi Hartwell, and was then confronted by the NXT Women’s Champion Mandy Rose and the NXT UK Women’s Champion Meiko Satomura, which set up a triple threat match to unify both the NXT UK Women's Championship and the NXT Women's Championship at the Worlds Collide pay-per-view on September 4. At the event, Davenport was unsuccessful in winning the titles.
On the May 30, 2023 episode of NXT, Davenport was revealed to be the attacker that left many of the women's division on the shelf. The following week on the June 6 episode of NXT, she defeated Dani Palmer, and later on in the night attacked Roxanne Perez. On December 9 at NXT Deadline, Davenport won the women's Iron Survivor Challenge to earn an NXT Women's Championship match against Lyra Valkyria at NXT New Year's Evil. At the event, Davenport was unsuccessful. On March 5 at NXT Roadblock, Davenport was defeated by Fallon Henley after a returning Sol Ruca cost her the match. On the April 2 episode of NXT, Davenport was defeated by Ruca. Two weeks later, Davenport knocked Ruca off the top rope, costing her a match against Lola Vice. Later that night, NXT General Manager Ava scheduled a match between the two for Spring Breakin' in a Beach Brawl match, where Davenport lost in her final match for NXT.
On night two of the 2024 WWE Draft, Davenport was drafted to the SmackDown brand. On the June 28 episode of SmackDown, Davenport made her main roster debut by failing to qualify for Money in the Bank ladder match in a qualifier triple threat match that included Naomi and Indi Hartwell, in which Naomi won. On the August 2 episode of SmackDown, during the tag team title match between WWE Women's Tag Team Champion The Unholy Union (Alba Fyre and Isla Dawn) and Bianca Belair and Jade Cargill, Davenport attacked Cargill, which resulted in The Unholy Union retaining their championship by disqualification while forming an alliance with Davenport.
