The IIconics

Before forming as a team, Kay (under her real name Jessie McKay) and Royce (as KC Cassidy) wrestled each other at Pro Wrestling Women's Alliance (PWWA) throughout their careers including a title match for the PWWA Championship.[7][8]

Both women joined WWE, where they were assigned to NXT, in 2015, originally under their ring names from PWWA. Cassidy made her debut on the May 15th episode of NXT, losing to NXT Women's Champion Sasha Banks in a non-title match.[9]

McKay and Cassidy were teamed up shortly after joining NXT, although they would only appear in house shows for over a year. Their first match as a team was on 8 May 2015 at a house show in Largo, Florida, where they lost to Bayley and Carmella in what was also McKay's first match in WWE.[10][11] For a period of over a year, the two were used as jobbers and lost all of their matches as a team, although they won a few separately; during that period, they were renamed Cassie (Royce) and Jessie (Kay), before taking on their names of Peyton Royce and Billie Kay in August 2015.[12][13]

The team made their TV debut on the 5 October 2016 episode of NXT, and were later dubbed "The Iconic Duo".[14] Almost a year and a half after the creation of their team, the duo picked up their first win on 14 October 2016 at a house show in Fort Pierce, Florida, defeating Aliyah and Liv Morgan.[15] They also won their first match on television on the 28 December 2016 episode of NXT, defeating Aliyah and Morgan again.[16] On 28 January 2017 at NXT TakeOver: San Antonio, the two were voted 2016's "Breakout of the Year" at the NXT Year-End Awards; they also competed at the event in their live TV debut, both losing in a fatal four-way match for the NXT Women's Championship won by defending champion Asuka.[17][18]

At NXT TakeOver: WarGames, Royce unsuccessfully competed in a fatal four-way match for the vacant NXT Women's Championship against Kairi Sane, Nikki Cross, and winner Ember Moon.[19] The duo's final televised match on NXT TV was on the 4 October 2017 episode of NXT in a loss against Cross and Ruby Riott, although they kept on competing in house shows; their final match as a part of the NXT brand was on 21 April 2018 at a house show in Fort Pierce, Florida, where they lost against Dakota Kai and Steffanie Newell; after the match, both teams hugged each other.[20][21]

Kay and Royce, now known as "The IIconics", debuted on the 10 April 2018 episode of SmackDown Live, attacking SmackDown Women's Champion Charlotte Flair, allowing Carmella to cash in her Money in the Bank contract and defeat Flair to win the championship.[22][23][24][25][26][27] The following week on SmackDown, The IIconics won their first match on the main roster by defeating Asuka and Becky Lynch.[28] On 6 October at Super Show-Down in their native country, they defeated Asuka and Naomi.[29]

In 2019, The IIconics entered their first Royal Rumble match at the eponymous event, eliminating Nikki Cross before being eliminated by Lacey Evans.[30] The following month at Elimination Chamber, they participated in the first female tag team Elimination Chamber match to determine the inaugural holders of the WWE Women's Tag Team Championship, eliminating Naomi and Carmella before being eliminated by Nia Jax and Tamina; the match was ultimately won by The Boss 'n' Hug Connection (Bayley and Sasha Banks).[31] In March, The IIconics started a feud with The Boss 'n' Hug Connection, whom they defeated in a non–title match on the 19 March episode of SmackDown.[32] .[33] Because of their win, they (and two other teams) challenged Banks and Bayley for the championship at WrestleMania 35 in a fatal four–way tag team match.[34][35][36] At the event on 7 April, The IIconics won the Women's Tag Team Championship after Kay pinned Bayley.[37] Their win made them the first all-Australian tag team champions in WWE history (the only previous occurrence of an Australian tag team champion was Buddy Murphy, who became NXT Tag Team Champion alongside American Wesley Blake in 2015), and the first Australians to win a title at WrestleMania.[5][38]

Two days later on SmackDown, in their first title defence, The IIconics defeated Kris Statlander and Karissa Rivera.[39] On the 17 June episode of Raw, the IIconics successfully defended their titles against Alexa Bliss and Nikki Cross.[40] On the 16 July episode of SmackDown, The IIconics retained their titles against The Kabuki Warriors (Asuka and Kairi Sane) via count-out.[41]

On the 5 August episode of Raw, the duo lost the titles to Bliss and Cross in a fatal four-way elimination match. They were the first team eliminated in the match, being knocked out by Mandy Rose and Sonya Deville. Their reign ended at 120 days.[42]

On 16 October, it was announced that The IIconics had been drafted to Raw as supplemental picks of the 2019 WWE Draft. On 28 October, the IIconics lost in a tag-team match against Charlotte Flair and Natalya. [43]

The team made their return on the 11 May 2020 episode of Raw, interrupting WWE Women's Tag Team Champions Alexa Bliss and Nikki Cross. They later defeated the champions in a non-title match. They unsuccessfully challenged for the WWE Women's Tag Team Championships multiple times throughout the summer. They also feuded with Ruby Riott, mocking her backstage for not having any friends. They would go on to trade victories as Kay and Royce defeated Riott while Riott defeated Kay. At Payback, The IIconics were defeated by Riott and her newly reunited tag partner Liv Morgan.[44] The following night on Raw, The IIconics were forced to disband after losing to The Riott Squad per stipulation.

As a result of the 2020 WWE Draft, Royce was drafted to Raw while Kay was drafted to SmackDown, solidifying the breakup.
