On January 29, 2018, the Philadelphia Fusion formally announced their academy team would be named Fusion University and begin competition in the North American region of Overwatch Contenders. In their first season of play, FU posted a perfect 5–0 record en route to qualify for the playoffs, where they capped off the season with victory over Toronto Esports to claim the 2018 Season 1 North America title. Following the win, the team fell to the Contenders Europe Champions British Hurricane in the 2018 Atlantic Showdown by a score of 1–3. The following season, Fusion University again posted perfect a 5–0 record in the group stages and defeated XL2 Academy in the 2018 Season 2 North America Grand Finals to win back-to-back regional titles. For the third season of 2018, the team, again, did not drop a match and defeated ATL Academy in the North America Grand Finals, taking home their third regional title in three seasons. Fusion competed in the North America East region for season one of 2019. Going into their last match of the group stages, FU had a 6–0 record and was set to face Mayhem Academy; Mayhem won the match 3–1, snapping Fusion's 30-game win streak. As the second seed, the team had a first-round bye for the first week of the playoffs, and went on to defeat Gladiators Legion in the finals to claim their fourth consecutive North America Contenders title. As the North America champions, Fusion qualified for the 2019 Atlantic Showdown, an interregional double-elimination tournament. The team did not lose a single match, and dropped only one map throughout its entirety, to claim the title of Atlantic Contenders Champions. After winning the first Atlantic Showdown, Fusion University announced that they would be moving from the North American division to compete in Korean Trials; the move was reportedly made to abide by the new region lock rules, which were implemented in 2019 Season 1, though FU was given a season-long grace period. The team qualified for Korea Contenders, but they struggled in the group stages, posting a meager 3–4 record. FU qualified for the Korea regional playoffs, but they fell in the quarterfinals to RunAway.
