Los Angeles Valiant

The team that would be the Los Angeles Valiant originally started out as the Overwatch team Immortals. Immortal's signed their first lineup on September 12, 2016, when the organization acquired the roster of the North American Overwatch team "Sodipop". The team competed for the first time during the Overwatch Open on September 25, 2017. Immortals placed 1st at NGE Winter Premier, Overwatch Carbon Series, and Overwatch Contenders 2017 Season Zero North America.

On July 12, 2017, Overwatch developer Activision Blizzard officially announced that Noah Whinston, CEO of esports organization Immortals, had acquired a Los Angeles-based Overwatch League franchise spot for an estimated $20 million, after almost a year of discussion. "For us, the crucial part of [our reason to join the Overwatch League] overall was the localization aspect — being able to have a local territory that we have control over and build deeper ties with a fan base than the current model really allows us to do," Whinston said in an interview. "That localization element, in addition the revenue sharing elements, and the stability and the strong competitive future of the game, all of those were important aspects for us when it came to making the decision."

On October 23, 2017, Immortals revealed their franchise name as the Los Angeles Valiant. The team revealed their starting roster over a series of Twitter posts from October 30 to November 2, consisting of four DPS, four tanks, and three supports.

Los Angeles Valiant's first OWL regular season game was a 4–0 victory against the San Francisco Shock on January 10, 2018. The Valiant posted an impressive 7–3 record in Stage 1, but did not qualify for the Stage 1 Playoffs. On February 19, two days before the beginning of Stage 2, the Los Angeles Valiant announced the departure of head coach Henry "Cuddles" Coxall. The team announced, on the same day, the hiring of Byung Chul "Moon" Moon as the team's new head coach. Stage 2 ended in a disappointing 4–6 record. The Valiant had a more successful Stage 3, as the team posted a 7–3 record – good for the 3rd seed in the Stage 3 Playoffs. The team faced off against the 2nd-seeded New York Excelsior in the semifinals of the Stage 3 Playoffs, but the Valiant lost in a 0–3 sweep Los Angeles Valiant had its best stage in the 4th stage. The team was undefeated going into the final regular season game against the Dallas Fuel. The Valiant lost that matchup by a score of 3 to 1, giving them a 9–1 record and the 2nd seed for the Stage 4 Playoffs. The Valiant faced their intercity-rivals and top-seeded team, the Los Angeles Gladiators, in the semifinals, and were able to pull off a 3–2 victory to move on the finals against the New York Excelsior. On June 17, the Los Angeles Valiant claimed their first-ever stage title, defeating the Excelsior 3–1 in the Stage 4 Finals. The Valiant ended the regular season with a 27–13 record and the 2nd seed and a first-round bye in the season playoffs. The team's was set to face the London Spitfire in the season semifinals. The first matchup was on July 18, in which the Valiant fell to the Spitfire by a score of 1–3. On July 20, the Valiant was eliminated from the season playoffs after getting swept 0–3 in the second semifinal match against the Spitfire.

The Valiant entered the 2019 season as the defending Pacific Division champions and looked to improve from their 2018 season. Los Angeles struggled in the first stage of the season, not winning a single match in Stage 1. With the poor start, the Valiant fired head coach Moon and Mike "Packing10" Szklanny took over as the interim head coach for the remainder of the season. The team's first victory came on April 12 in a 3–2 win over the Atlanta Reign. The Valiant finished Stage 2 with an improved, but disappointing, 3–4 record. After the All-Star break, the Valiant hit their stride. Highlighted by a 3–1 win over the undefeated Vancouver Titans, the Valiant amassed a 5–2 record in Stage 3 to claim the sixth seed in the Stage 3 Playoffs. After taking down the Hangzhou Spark 3–2 in the quarterfinals, the Valiant fell to the San Francisco Shock, 0–4 in the semifinals. Despite the team's resurgence, a 0–4 to the Shock in the final match of the regular season prevented the Valiant from qualifying for the season playoffs.

For the 2020 season, the Valiant debuted new colors, trading the green and yellow color scheme that the team had used for two years in favor of blue and yellow. On August 22, the Valiant clinched a spot in the season playoffs with a win over the Vancouver Titans. In the first round of the North America bracket, Los Angeles defeated the Florida Mayhem by a score of 3–2. The following day, the Valiant were swept by the Philadelphia Fusion in the second round of the upper bracket, sending them to the lower bracket. A 1–3 loss to the Washington Justice in the subsequent round eliminated the Valiant from the playoffs.

In the offseason preceding the 2021 season, the Valiant made several roster acquisitions, planning to compete in the league's Western division. However, in mid-January 2021, the team announced that it would be relocating to the China to compete in the league's Eastern region. The decision to make the move was in response to a suggestion made by Overwatch League, as the league needed more teams in its Eastern region. On January 29, the Valiant released their entire roster and most staff, with Immortals Gaming Club citing visa issues in the move to China for the reason. The decision was met with heavy criticism by fans and analysts; as all team's were required to have at least seven players signed by January 4, 2021, many team rosters were already full, leaving few options for the dropped players. Several weeks later, the Immortals signed a one-year operating agreement with Chinese esports organization LinGan e-Sports (LGE), in which LGE would not acquire any share in the Valiant, nor claim any ownership. In mid-March 2021, the Valiant announced its six-player roster, consisting partly of previously retired and controversial players, which would be led by head coach Zhang "JpCat" Peng. The Valiant had their worst season in franchise history, finishing the 2021 regular season in last place with a 0–16 record. The finish made the second team in OWL history to have a winless season.

In December 2021, the Valiant announced that they would continue to compete from Asia in the Eastern division, and LGE would continue to operate the team throughout the 2022 season.

In February 2023, the Valiant announced their return to the Western division for the 2023 Season and later in March signed a completely North American roster ahead of Pro-Am West.

In October 2023, following the termination of the Overwatch League, the Valiant ceased operations.
