Immortals was announced on October 7th, 2015 as a new esports franchise and also the new brand of Team 8, with that roster being their first of multiple planned esports teams. Soon after the team's creation, support player Dodo8 became the team's player manager, retiring from competitive play. Immortals ended up with an entirely different roster from the Team 8 players that they started with: on December 8th, they announced Huni, Reignover, Pobelter, WildTurtle, and Adrian as their roster for the 2016 season.
Expected to be a top team in the LCS, Immortals initially exceeded all expectations as they went undefeated for the first six weeks of the season before losing one game to reigning champions Counter Logic Gaming in week 7. They won the rest of their regular season games, but as the season progressed further they looked weaker and weaker as a team, and even seemed to falter against the last-place Team Dignitas, needing to come back against them to pull out a win. With a top seed clinched into the playoffs, Immortals were guaranteed to face the lowest-seed team that won in the quarterfinals. That team ended up being Team Solomid, who were on a strong upswing after a sixth-place regular season finish. With questionable drafts including a Lucian top for Huni in game 1, Urgot mid for Pobelter in game 2, and three games of Karma support for Adrian as well as not a single contest of the strongly-in-meta Ekko, Immortals lost 3-0 to TSM. They came back the next week to beat Team Liquid and finish in third place overall.
In their second game of the NA LCS 2016 Spring Split, both set the record for the fastest game to date in NA LCS history and also achieved the second perfect game ever in NA LCS history.
