Nicola Glencross (born 21 April 1989) is a Scottish professional wrestler. She is currently signed to WWE where she performs on the Raw brand under the ring name Nikki Cross and is a member of The Wyatt Sicks faction. In WWE, she is a former one-time Raw Women's Champion, a three-time WWE Women's Tag Team Champion, and an 11-time and final WWE 24/7 Champion.
Glencross began her wrestling career on the independent circuit with the name Nikki Storm, most notably working for Insane Championship Wrestling, Pro-Wrestling: EVE, and Shimmer Women Athletes. In 2016, Glencross signed a contract with WWE, altering her ring name to Nikki Cross. In her first years with the company, she was in the NXT brand as part of the stable Sanity. Her first character gimmick was that of a psychopathic and unhinged woman who would suffer mood swings. In mid-2018, Sanity was drafted to SmackDown without Cross, who stayed in NXT.
Cross was promoted to the main roster in December 2018. In 2019, Cross was drafted to Raw and formed a tag team with Alexa Bliss, winning the WWE Women's Tag Team Championship twice. From June 2021 to October 2022, Glencross' character became a faux-superhero known as Nikki A.S.H. (standing for "Almost A Superhero"). As Nikki A.S.H., she won the Money in the Bank contract and successfully cashed it in the next day to become Raw Women's Champion. She also won the WWE Women's Tag Team Championship alongside Rhea Ripley. In 2022, she reverted back to the Nikki Cross name and persona.
