Kay and Royce, now dubbed The IIconics, made their main roster debut on the 10 April 2018 episode of "SmackDown Live" attacking then SmackDown Women's Champion Charlotte Flair, whilst she was cutting a promo about her match at WrestleMania 34. Week later, Kay lost to Flair. In their first match together as part of the main roster, The IIconics racked up their first victory against Asuka and Becky Lynch. Throughout the next few months, Kay competed in various singles and tag team matches but ended up on the losing end. In August, The IIconics started their first feud on the main roster, with Naomi, and the two were able to defeat her in singles matches. Eventually, Naomi teamed up with Asuka but lost to the IIconics at the Super Show-Down on 6 October, held in the latter's homeland of Australia. Three weeks later, both Kay and Royce took part in WWE's first all-women's pay-per-view, Evolution; they were the first two eliminated from a battle royal for a future women's championship match.
