Niebla Roja

Chávez wrestled in the main event of the CMLL 84th Anniversary Show, losing the match and his mask to Gran Guerrero.

Sergio Chávez and his younger brother Miguel, better known under the ring name Ángel de Oro, are both sons of professional wrestler Apolo Chávez and grew up idolizing their father, hoping to follow in his footsteps.

Sergio Raymundo Chávez Velasco (born March 20, 1986), better known by his ring name Niebla Roja (Spanish for "Red Mist"), is a Mexican luchador (or professional wrestler), who currently works for the Mexican wrestling promotion Consejo Mundial de Lucha Libre (CMLL).

He made his professional wrestling debut in 2006, under the name Guerrero Inca (Incan Warrior), as an enmascarado, or masked wrestler, working mainly in the local Gómez Palacio, Durango area.

Early in his career he would often work opposite his brother as the two developed an in-ring feud without revealing that they were related.

He previously worked as Ángel de Plata (Spanish for "Silver Angel") between 2008 and 2012 before adopting his current ring name.

A second-generation wrestler, he is the son of retired wrestler Apolo Chávez, and the brother of Miguel Ángel Chávez Velasco, who is also a luchador under the ring name Ángel de Oro (Spanish for "Golden Angel").

Chávez has been working for CMLL since 2008.

He is a former CMLL World Light Heavyweight Champion and CMLL World Tag Team Champion.

He is also a former CMLL World Trios Champion as part of Los Guerreros Laguneros with Euforia and Último Guerrero.

The feud led both Chávez to work for International Wrestling Revolution Group (IWRG) on opposite sides, but Sergio broke his arm in early 2008 and he did not compete for eight months.

In Durango he feuded with his younger brother, in a feud that was so well received by the crowd that the siblings received an invitation to train at Consejo Mundial de Lucha Libre's (CMLL) wrestling school in Guadalajara, Jalisco.

When he went to Guadalajara to train under Gran Cochisse and El Satánico he changed his ring character to Ángel de Plata, to complement his brother's ring character.

The duo made their CMLL debut on July 4, 2008 wrestling as a team dubbed Los Angeles Celestiales ("The Celestial Angels").

The duo was made into a trio when they were joined by Ángel Azteca Jr. who used a similar "Angel inspired" ring character.

Los Angeles Celestiales worked low card matches throughout 2008 and into 2009, gaining valuable ring experience along the way.

On April 7, 2009 Ángel de Plata participated in a 10-man Torneo cibernetico for the vacant CMLL World Super Lightweight Championship.

The other participants included Ángel Azteca Jr., Rey Cometa, Pegasso, Tiger Kid, Pólvora, Inquisidor, Súper Comando, Angel de Oro and eventual winner Máscara Dorada.

In the fall of 2009 Ángel de Plata participated in the 2009 Gran Alternativa tournament, a tournament where an experienced wrestler teams up with a newcomer.

Ángel de Plata teamed up with Héctor Garza and together they defeated Averno and Pólvora in the first round, before losing to eventual tournament winners La Ola Amarilla ("The Yellow Wave"; Naito and Okumura).

In late 2009 Los Ángeles Celestiales participated in a tournament to crown new Mexican National Trios Champions.

The team lost in the first round to Los Cancerberos del Infierno (Virus, Pólvora and Euforia. Following the tournament loss Los Ángeles Celestiales and Los Cancerberos del Infierno have developed a rivalry between the two groups, facing off on various CMLL shows, including their Friday night CMLL Super Viernes show. January 15, 2010 Super Viernes Ángel de Plata lost a Lighting match to Raziel, one of the members of Los Cancerberos del Infierno, continuing the building storyline between the two factions. Ángel de Plata was one of 12 men who put their mask on the line as part of a 12-man steel cage match in the main event of the 2010 Infierno en el Ring. During the match he tricked his brother Ángel de Oro in order to escape the match.

In the end Ángel de Oro defeated Fabián el Gitano in the Lucha de Apuestas (bet match) portion of the match to unmask him.

Following the match Ángel de Plata returned to the ring to celebrate with his brother, showing that there were no hard feelings over Ángel de Plata's tactics during the match.

On March 30, 2012, Ángel de Plata underwent a complete character overhaul, debuting a new mask and attire and switching his ring name to Niebla Roja ("Red Mist"), while also turning rudo in the process.

On July 6, Niebla Roja was named the newest member of Último Guerrero's Los Guerreros del Infierno stable.

Niebla Roja competed in CMLL's inaugural En Busca de un Ídolo ("In search of an Idol") tournament, but did not qualify for the semi-final.

Niebla Roja was forced to team up with Dragón Rojo Jr. from Los Revolucionarios del Terror rival group for the 2013 Torneo Nacional de Parejas Increibles ("National Incredible Pairs Tournament") where the concept was that rivals would team up for a tag team tournament.

Despite being rivals the duo managed to defeat the team of Rush and El Terrible in the first round and Blue Panther and Rey Escorpión in the second round.

The team was defeated in the semi-finals by Niebla Rojo's stable leader Último Guerrero and Atlantis.

From January 14 to 19, 2014, Roja worked the New Japan Pro-Wrestling (NJPW) and CMLL co-produced Fantastica Mania 2014 tour, which marked his debut in Japan.

On March 28, 2014, Roja won his first title, when he, Euforia and Último Guerrero defeated Los Estetas del Aire (Máscara Dorada, Místico and Valiente) for the CMLL World Trios Championship.

They lost the title to Sky Team (Místico, Valiente and Volador Jr.) on February 13, 2015.

In March 2017, CMLL began a storyline where Niebla Roja started having problems with his fellow Los Guerreros Laguneros teammates, initially by accidentally causing them to lose matches due to miscommunication between Niebla Roja and Euforia and Gran Guerrero.

As the storyline progressed Niebla Roja refused to participate in Los Guerreros rudo antics such as double or triple teaming an opponent.

On May 19 Niebla Roja's tecnico turn was completed as he kicked Los Guerreros leader Último Guerrero in the face during a match.

Afterwards Último Guerrero and Gran Guerrero beat Niebla Roja up, tore his mask off and demanded that Niebla Roja had to come up with a new mask instead of wearing the Último Guerrero inspired mask.

During the attack he was aided by his brother Ángel de Oro.

On June 10, 2017, Niebla Roja won a 10-man torneo cibernetico elimination match to win the vacant CMLL World Light Heavyweight Championship.

The long running storyline with Los Guerreros, especially Gran Guerrero led the main event of CMLL's 84th Anniversary Show on September 16, 2017.
