Thanos

In "Squid Game" Season 2, Thanos (Player 230) is a purple-haired, self-absorbed, and callous internet rapper who becomes one of the main antagonists. He's portrayed by Choi Seung-hyun, a former member of the K-pop band Big Bang. Thanos's character is motivated by a desire to play the Squid Game, not for financial gain, but for the entertainment it provides, and he forms a team called the Thanos Crew to dominate the games.
