Nicola Glencross is a Scottish professional wrestler. As of February 2024, she is signed to WWE, where she performs on the Raw brand under the ring name Nikki Cross. She is a one-time WWE Raw Women's Champion, 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 under the ring name Nikki Storm, most notably performing for Insane Championship Wrestling, Pro-Wrestling: EVE, and Shimmer Women Athletes. In 2016, Glencross signed a contract with WWE, changing her ring name to Nikki Cross. During her first years with the company, she worked on 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.
Glencross 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-inspired 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.
In 2019, Glencross married her long-time boyfriend and former Sanity stablemate, Damian Mackle, better known as Killian Dain. In 2023, she graduated from the University of Edinburgh with a master's degree in history.
