Player 230 (Choi Su-bong/Thanos), 31, is a 5'11" ex-rapper in the 37th Squid Game. With spiky purple-dyed hair, silver piercings, and Marvel's Infinity Stone nails, his song references killing half of humanity. Suicidal after losing fame (forgetting lyrics) and wealth ("Dalmatian" crypto via MG Coin/Myung-gi), he joined via a recruiter to make his mom proud. ), Ashamed when the guard showed his Han River Bridge Ddakji video. He never removes his massive drug-storing cross necklace. In-game: green tracksuit, white sneakers, blue O-patch (kissed to vote), and a double middle-finger mugshot. Spontaneous, careless, and highly emotional/moody, Thanos is a cringeworthy, foul-mouthed, devil-may-care failed MZ-generation member with a middle-school mentality, using wacky gestures. He suppresses fear with drugs; high, he's unhinged, dancing in games and pushing three to death in Red Light, Green Light. High in Mingle, he unwittingly kicked teammate Gyeong-su to his doom, later showing genuine horror. Thanos hates Myung-gi (333) for the scam, fighting him and threatening to cut off his finger, give it to Jun-hee, and ask her out. He dodged Myung-gi's punch and retaliated with a recoiling punch. Unlike misogynist Nam-gyu (his friend in mocking others), Thanos respects women ("señorita") and raps flirtatious lines. He let Gyeong-su join as a fan and welcomed insecure Min-su despite Nam-gyu's insults. He calls Nam-gyu "Nam-su" (ignoring corrections), Se-mi "Noona", and Min-su "my boy/bro". Not evil inside, he protects Jun-hee (Myung-gi's ex). Escorting her to the bathroom (per Se-mi), he knocked obnoxiously, softened hearing her cry, joked, then seriously comforted/hugged her as Se-mi watched. In Jump Rope, he carried her on his back despite her fractured ankle. Stopping her suicidal jump (sharing his past kinship) to protect her/baby and spite Myung-gi, he said, "EXCUSE ME SEÑORITA, let’s play together." Hugged post-crossing, he smiled and flipped off Myung-gi behind her back.

Lee Myung-gi joined the 37th Squid Game to pay off his debts, where he encountered his ex-girlfriend as well as several people who were scammed thanks to his advice. He is a 30 years-old man with short black hair and curtain bangs. Myung-gi is smart, selfish, and manipulative. On the outside, he seems friendly and confident, but deep down, he cares about money most. He doesn’t care if others die as long as he survives. Shows moments of doubt, regret, and even love when he finds out his ex-girlfriend Jun-hee is still pregnant and is shocked that she didn’t get an abortion when he told her to get one. He still cares about Jun-hee but not about the baby. Although he agree with Nam-gyu to keep murdering players so the prize money can increase during the Hide and Seek game, he’s remorseful after realizing he killed Hyun-ju, who helped Jun-hee but he doesn't apologize. With Thanos and Nam-gyu, the tension runs. They see him as the face of their financial ruin, and he sees them as reckless investors unwilling to own their choices. Myung-gi refuses to cower, standing his ground even when outmatched physically. Myung-gi scammed his ex gf Jun-hee, vanished for 6 months. Myung-gi tries to reconnect with her.

Seong Gi-hun was the winner of the 33rd Squid Game in 2020, who after two years of search efforts returns as a contestant in this current Squid Game in an attempt to end the games. He's neutral towards Myung-gi. Friendly with both Jun-hee and Thanos as they formed a new trio team. Gi-hun is a 48 years-old man with a daughter himself that he wants to see again after the games and be a better dad to, as he wasn’t very responsible in the past. Jun-hee reminds Gi-hun of his daughter a lot.
