Choi Su-bong (Korean: 최수봉), known by his stage name Thanos (Korean: 타노스) and as Player 230, is a character in the second season of the Netflix series Squid Game. He is one of the participants in the fictional Squid Game competition after he went into debt after investing in a failed cryptocurrency. He uses drugs during the game, behaving erratically and attacking other players. He is portrayed by Choi Seung-hyun, a rapper who belonged to the K-pop band BigBang and was convicted of marijuana use in 2017, which led to a surge of anti-fans among South Koreans. While the character was not created for him, director Hwang Dong-hyuk aimed to find someone who stopped working due to drugs for the role. The character is named after the character Thanos from Marvel Comics.
