Trinidad is also known for her time in Total Nonstop Action Wrestling as Rosita, where she was a one-time TNA Knockouts Tag Team Champion with Sarita, and for various independent promotions under her real name.

She debuted on WWE's NXT brand in 2017 under the ring name Zelina Vega, where she predominantly served as the manager of Andrade "Cien" Almas.

Zelina Vega was born as Thea Megan Trinidad in the Queens borough of New York City on December 27, 1990, and is of Afro-Latin Puerto Rican descent.

[7] When she was 10 years old, her father, Michael Angel Trinidad, was killed in the September 11 attacks; he had worked as a telecom analyst for Cantor Fitzgerald at the World Trade Center,[7][9] and was on the 103rd floor of the North Tower when it collapsed.

[13] On February 20, 2010, she made her debut for Women Superstars Uncensored (WSU), under the ring name Divina Fly in a losing effort against Brittney Savage.

[20] In the following weeks Rosita and Sarita successfully defended the Knockouts Tag Team Championship first against The Beautiful People (Angelina Love and Velvet Sky) and then against Madison Rayne and Tara.

[26] On the March 22, 2012, episode of Impact Wrestling, Rosita and Sarita again failed to recapture the Knockouts Tag Team Championship, when they were defeated by Eric Young and ODB.

[27] On April 19 episode of TNA Impact, Rosita and Sarita teamed up with Madison Rayne and Gail Kim in a losing effort to Brooke Tessmacher, Tara, Velvet Sky and Mickie James.

[28] Rosita and Sarita were given another title opportunity on April 15 at Lockdown, but were once again defeated by Eric Young and ODB, this time in a steel cage match.

[29] Afterwards, both Rosita and Sarita went inactive from TNA, while Anarquia left the promotion and Hernandez turned face, effectively ending Mexican America.

[32] In late August 2011, Rosita traveled to Mexico to attend an event held by the Consejo Mundial de Lucha Libre (CMLL) promotion, for which Sarita regularly works under the ring name Dark Angel.

[35] On May 14, 2011, Rosita made her in-ring debut for Family Wrestling Entertainment (FWE) at the Meltdown pay-per-view, losing to fellow knockout Winter with Christy Hemme as the special guest referee.

[36] Rosita made her return to the promotion on March 24, 2012, at the Welcome to the Rumble pay-per-view, where she unsuccessfully challenged Maria Kanellis for FWE Women's Championship in a three-way match, after Winter pinned her to become the new champion.

[38] She debuted for the promotion on June 12, 2015, where she defeated Lei'D Tapa at the first show of the GFW Grand Slam Tour in Jackson, Tennessee.

[54] At Evolution on October 28, Vega competed in a battle royal for a future women's championship match, but was eliminated by eventual winner Nia Jax.

[59] With Andrade and new tag team partner Angel Garza arguing and fighting each other constantly, Vega appeared to end her association with her clients on the September 14 edition of Raw, interrupting and confronting Asuka after she defeated Mickie James, initiating a feud.

[60] The following week, Vega defeated James to earn a title match against Asuka for the Raw Women's Championship at Clash of Champions on September 27,[61][62] which she lost via submission.

[66] It was later reported that the release was due to Trinidad's opposition to WWE "requiring talents to acquiesce control" of their accounts on third-party platforms.

[70] Vega, with specially designed ring gear, was originally scheduled to wrestle on the September 10, 2021, episode of SmackDown held in Madison Square Garden but her match was ultimately cut for time.

[72] Before that, Vega entered the inaugural Queen's Crown tournament, representing SmackDown, where she defeated Toni Storm in the first round[73] and Carmella in the semi-finals.

[81] On the second night of WrestleMania 38 on April 3, Queen Zelina and Carmella lost the titles in a fatal four-way tag team match to Sasha Banks and Naomi, which also involved Liv Morgan and Rhea Ripley and Natalya and Shayna Baszler, ending their reign at 131 days.

[83] After a seven-month hiatus, Vega returned on the October 7, 2022, episode of SmackDown, aligning herself with Legado Del Fantasma and attacking Hit Row.

[85] On the March 10 episode of Smackdown, Vega joined Legado Del Fantasma in helping Rey Mysterio against The Judgment Day, turning face for the first time in her WWE career.

[86] On the March 31 episode of SmackDown, Rey reformed the Latino World Order and invited Legado Del Fantasma to join as a token of appreciation for aiding him in his fight against his son, Dominik Mysterio, and The Judgment Day.

[10] In August 2023, Trinidad alongside New Zealand professional wrestler Cheree Crowley (best known as Dakota Kai), launched a new podcast called "ZELVXandCharlieGirl".
