Thanos

Choi Su-bong (최수봉) is portrayed by rapper, singer, songwriter, and actor Choi Seung-hyun, better known by his stage name "T.O.P." In 2017 (seven years prior to his casting in Season 2), T.O.P, pled guilty to drug use and was blacklisted in the Korean music industry. During the scandal, he was hospitalized after overdosing on anxiety medication. Prior to Choi Su-bong's entry in the Squid Game in 2024, he gained fame as a rapper under the stage name "Thanos". At some point, he would go on to win second place in Rap Battlegrounds, a rap battle tournament, missing first place after forgetting his lyrics. He was also an avid fan of YouTuber Lee Myung-gi, and claims to have watched every video posted under his channel "MG Coin".
