Guerrero was born in El Paso, Texas, and is the eldest daughter of Vickie Guerrero and the late Eddie Guerrero. Guerrero has a younger sister named Sherilyn Amber Guerrero, and a half-sister named Kaylie Marie Guerrero. Prior to joining WWE, Guerrero was a singer and a model while attending New Mexico State University. She has sung the national anthem at Florida Championship Wrestling events.
In October 26, 2010, World Wrestling Entertainment signed Guerrero to a developmental contract, and she was assigned to Florida Championship Wrestling, WWE's developmental territory, based in Tampa, Florida. She made her debut in December 2010, appearing at ringside for a FCW Divas Championship match between AJ Lee and Naomi Knight. She made her in-ring debut at the February 11, 2011, television tapings under the ring name Raquel Diaz, where she and Naomi lost a tag team match to AJ and Aksana. She briefly acted as the manager for Alexander Rusev, before joining The Ascensionfaction, with Conor O'Brian, Kenneth Cameron, and Tito Colon, all of whom she began managing. On the November 17 episode of FCW TV, Diaz defeated Aksana to become the new Queen of FCW. A month later, on the December 15 episode of FCW TV, Diaz defeated Audrey Marie to win the FCW Divas Championship, holding both the championship and the crown simultaneously. She retained the championship against Marie and Sofia Cortez, before FCW General Manager Summer Rae deactivated the Queen of FCW crown, leaving Diaz as the last champion, with her reign ending at 119 days. Diaz again defeated Audrey Marie to retain the championship in April. After losing a triple threat match to Paige in May, Diaz defended and successfully retained the championship against Paige by disqualification. Diaz lost the FCW Divas Championship on June 29 during a live event to Caylee Turner, ending her reign at 197 days.
NXT (2012–2014)
WWE went on to re-brand FCW into NXT, taped at Full Sail University in Orlando, Florida. Diaz's NXT television debut took place on the July 18, 2012, episode of NXT under the character of an "ultra diva" on an "exfoliating ugliness tour", and defeated Paige in a singles match. As part of her new character, she began drawing "L"s on the foreheads of other Divas after defeating them. On September 27, 2012, it was reported that Guerrero had requested and been granted a release from her developmental contract. Guerrero confirmed her departure from WWE three days later. In September 2013, Guerrero returned to WWE's developmental territory. At this time, it was reported that she was never officially released, but was given a leave of absence to attend school. On April 30, 2014, it was reported that WWE had released Guerrero, with her failing to appear on television during her second run with the company. In August 2014, Guerrero stated that she left WWE due to an ongoing eating disorder.
In 2018, Guerrero started performing burlesque in the Chicago area under the stage name Miss Nyxon. That same year, she appeared in the annual Maxim Cover Girl social media contest, finishing third in the Southwest Group Twelve.
