Moreno described himself as a boxing fan growing up but was not aware of other combat sports. He later became interested in capoeira, but was unable to find a school in his home city. While searching, he found an MMA gym and began training in kickboxing and jiu-jitsu.[10]
Early career
Moreno made his professional MMA debut in his native Mexico in April 2011. Over the next two years, he amassed a record of 6 wins and 3 losses.
In 2014, Moreno would debut for the World Fighting Federation promotion. He would go 5–0 in the promotion and would eventually win the Flyweight championship, which led to him being cast in the Flyweight tournament on the 25th season of The Ultimate Fighter.
In a rare move, Moreno debuted in the UFC while his season of The Ultimate Fighter was still airing. He faced Louis Smolka at UFC Fight Night: Lineker vs. Dodson on October 1, 2016.[13] Moreno won the fight via submission in the first round. The win also earned Moreno his first Performance of the Night bonus award.[14]
Moreno next faced Dustin Ortiz on April 22, 2017, at UFC Fight Night 108.[18] He won the fight by submission in the second round and was awarded a Performance of the Night bonus.[19][20]
Moreno faced Sergio Pettis on August 5, 2017, at UFC Fight Night 114.[21] He lost the fight via unanimous decision.[22] Moreno subsequently tested positive for clenbuterol from an in-competition urine sample collected on August 6, 2017, a day after his fight with Pettis. USADA has determined that the presence of clenbuterol in Moreno's system likely resulted from clenbuterol-contaminated meat that Moreno had consumed in Mexico, and so Moreno was not punished by USADA.[23]
Moreno was expected to face Ray Borg on April 7, 2018, at UFC 223.[24] However, the bout was canceled after Borg was injured by glass from a bus window that was smashed by Conor McGregor.[24][25] The pairing was left intact and quickly rescheduled and was expected to take place on May 19, 2018, at UFC Fight Night 129.[26] However, Borg withdrew from the bout to take care of his child from brain surgery,[27] and was replaced by Alexandre Pantoja.[28] Moreno lost the fight by unanimous decision.[29] In an interview in 2019, Moreno revealed that he had been cut from the UFC in late 2018.[30]

Moreno rematched Figueiredo for the UFC Flyweight Championship on June 12, 2021, co-headlining UFC 263.[48] Moreno dominated the striking and grappling exchanges and submitted Figueiredo with a rear naked choke in the third round, becoming the first Mexican UFC champion in the process.[49] This win earned him the Performance of the Night award.[50]
The trilogy rematch with Figueiredo for the UFC Flyweight Championship was scheduled to take place on December 11, 2021, at UFC 269 initially,[51] but was moved to UFC 270 as the co-main event.[52] He lost the fight and the title via unanimous decision.[53] This fight earned him the Fight of the Night award.[54]
