In "Squid Game" season one, Player 001 was the mastermind of the games. Here's what we know so far about the character in season two.

The second season flashes forward a few years after Seong Gi-hun (Lee Jung-jae), a.k.a. Player 456, won the games. The trauma of everyone's death from Season 1 still weighs heavily on Gi-hun's conscience, causing him to devote himself and the $45.6 billion won (about $31 million dollars) he won to finding and ending the games once and for all.
