Who plays Nam-gyu (aka Player 124) in Squid Game? Meet Thanos's evil heir
The unpredictable character is more dangerous than ever in season 3.

If you thought Squid Game would get a bit less chaotic without rapper Thanos (Choi Seung-hyun) in the competition, you're in for a big surprise as his former sidekick steps up to fill the void.
Nam-gyu (aka Player 124) was never far from Thanos's side in the second season, sharing his recreational pills and encouraging his intimidating, dangerous and generally cruel behaviour.
Korean actor Roh Jae-won reprises the role for this third and final season, which sees the remaining players reconvene in the dormitory following a failed rebellion against the Squid Game organisers.
While some, most notably Gi-hun (Lee Jung-jae), are devastated by what they have experienced, others are raring to get back to the games and a few inches closer to the life-changing prize money.
Suffice to say, Nam-guy falls into the latter category – here's what you need to know about Squid Game season 3's agent of chaos.
Who is Nam-gyu in Squid Game season 3?

Nam-gyu is Player 124 in Squid Game season 3 and one of the most dangerous individuals in this latest edition of the horrific tournament.
In season 2, he quickly allied himself with disgraced rapper Thanos (Choi Seung-hyun), sharing his party pills to ease their nerves, which led to comical moments such as dancing arm-in-arm on the spinning carousel in Mingle.
However, it also made their behaviour increasingly erratic, with Thanos targeting fallen crypto influencer Myung-gi (Yim Si-wan), while Nam-gyu became increasingly aggressive towards their acquaintance Se-mi (Won Ji-an).
