Vancouver Titans

On September 7, 2018, Activision Blizzard announced that NHL's Vancouver Canucks ownership Aquilini Group had purchased a slot for the Vancouver-based franchise for a reported $30 million to $60 million. "Esports has seen extraordinary success and continues to be one of the fastest growing industries in the world," said Aquilini Group managing director Francesco Aquilini in a statement. "We can't wait to launch the team in Vancouver." On October 18, the team announced they had partnered with Canadian esports organization Luminosity Gaming to add esports expertise to the organization.

On December 1, a video revealed the Vancouver Titans' brand during the second intermission of a Vancouver Canucks game, concluding with "Today, we release the Titans." The team also announced that it had signed all eight members of the Korean Overwatch Contenders champions RunAway and Hwang "Pajion" Ji-sub as the team's head coach.

2019: Grand Finals appearance

Vancouver's first OWL match was a 4–0 sweep over the Shanghai Dragons. Behind a core starting lineup of Park "Bumper" Sang-beom, Choi "JJANU" Hyun-woo, Kim "Haksal" Hyo-jong, Seo "SeoMinSoo" Min-soo, Kim "SLIME" Seong-jun, and Lee "Twilight" Ju-seok, the Titans posted a 7–0 record in the first stage of the season. The team capped off the stage running through the Stage 1 playoffs, going on to defeat the San Francisco Shock, 4–3, in the Stage 1 finals. The Titans reached the Stage 2 finals, going undefeated in the process, where they again faced the Shock. However, their undefeated streak came to an end, as they lost the match, 2–4. The Titans recorded an OWL record 19-game regular season winning streak, which was snapped Stage 3, as they lost their first regular season match on June 23, against the Los Angeles Valiant. While they qualified for the Stage 3 playoffs, Vancouver was defeated by the Shanghai Dragons in the semifinals round. The league introduced a 2-2-2 role lock for Stage 4; on August 16, the Titans signed tank player Hwang "TiZi" Jang-hyeon, who was a former player for RunAway. Vancouver ended the regular season with a league-best 25–3 record and the top seed in the season playoffs. Haksal and Twilight were awarded Role Star commendations on the season; Haksal was also named the OWL Rookie of the Year. In the season playoffs, Bumper and TiZi split playing time, with TiZi taking more time as the playoffs went on. Vancouver ran through the upper bracket of the season playoffs, ultimately defeating the New York Excelsior, 4–3, in the upper bracket finals to advance to the Grand Finals. In a rematch of the Stage 1 and Stage 2 finals, the Titans faced the Shock in the Grand Finals on September 29. However, the Titans were held without winning a single map in the series, losing 0–4, and finished as the league's runners-up.

2020–present: Roster collapse and years of rebuilding

Following the 2019 season, the Vancouver Titans parted ways with four of their players, including Bumper and TiZi. The team signed two former Seoul Dynasty players in tank Baek "Fissure" Chan-hyung and support Ryu "ryujehong" Je-hong. The team began their season living in Vancouver and practicing at a gaming facility at Adamas Esports Training and Performance at Fortius Sport & Health. With the emergence of the COVID-19 pandemic, the Overwatch League shifted all matches to an online format. The Titans players requested to move back to South Korea amid the pandemic, which was approved by Aquilini management. However, Aquilini would not fund the team a team house, nor would they provide a training facility for them to practice at. In South Korea, the Titans players encountered technical difficulties playing from their homes and eventually boycotted practice. According to Tim Holloway, esports director of Aquilini Group, the Titans originally planned to compete in the league's newly formed Asia region, but the time difference "made it difficult for management and the home fanbase to connect with the team and technical challenges for the players playing from home further exacerbated the situation." Unable to resolve differences between players and management, the Titans organization parted ways with tank JJANU and head coach Pajion on April 30 and released the rest of their roster on May 6. Days later, the Titans announced the hiring of Steven "Flubby" Coronel as their new head coach and signed a roster consisting entirely of the players from North American Overwatch Contenders team Second Wind. The team struggled throughout the season, finishing with a 6–15 regular season record. A 0–3 loss to the Washington Justice in the North America play-in tournament on September 3 ended the team's season.

Prior to the start of the 2021 season, the Titans retained half of their roster from the previous season and picked up underperforming players who were dropped or traded from other OWL teams to fill their holes. The team did not outperform expectations, going on a 12-game losing streak to start the season. Vancouver picked up its first win of the season on August 6, 2021, with a 3–0 win over the Boston Uprising — their first win in nearly a year. The Titans ended the season with a 1–15 record, marking their worst finish in franchise history.

After an abysmal 2021 season, the Titans again dropped their entire roster. The team picked up seven players, forming a mixed nationality roster, in the offseason, including former Toronto Defiant hitscan player Luka "Aspire" Rolovic and former Atlanta Reign support player Petja "Masaa" Kantanen.
