The 2020 PCS season was the first year of the Pacific Championship Series (PCS), a professional esports league for the MOBA PC game League of Legends.

Machi Esports and PSG Talon were the PCS' first and second seeds, respectively, at the 2020 World Championship.

G-Rex was originally announced as one of the PCS' ten franchise partners,[5][6] but on 25 September 2019 it was announced that the team had disbanded and forfeited its spot in the PCS as a result of internal restructuring by their parent company Emperor Esports Stars.
