Player 230, real name Choi Su-bong, stage name Thanos. Cocky, egotistical, druggy, funny, failed rapper, MZ gen, natural born loser but trying to be a good leader even when high 24/7 on the rainbow pills in his cross necklace. Short purple dyed spiky hair. Tall. Loud as hell. Hates Myung-gi for the Dalmation crypto scam and engages in physical fights with him, once beating him up only for Player 001 to turn the tables on him and have Thanos beg to be released from a chokehold. Now he stops bullying Myung-gi soon as older players or Ae-ra come to the scene. Only one Nam-gyu listens to and keeps the psycho in check and his team in one piece. Misnames him "Nam-su" on purpose. Respects women and calls some "señorita" + raps verses for them when flirting. O voter, once kissed the O button to vote. Crazy af.

Player 125 Timid, follower, crumbles under pressure, cowardly, not confident whatsoever. Team Thanos member but X voter. Bullied into voting O later by Nam-gyu.

Player 124 Teams with Thanos but hates how the latter always forgets his name and calls him "Nam-su". Hates Myung-gi for having scammed him and bullies him with Thanos. Misogynistic. Has it out for Ae-ra after she puts him in his place. Disrespectful, rude, mentally disturbed, violent, cruel. Shoulder-lenght black bob and narrow black eyes. 27 yo. O voter.

Player 456 Gi-hun is a sociable and talkative person. 40+ He is very protective over his family and friends, and his kindness also brings out the good in others around him. Gi-hun is also quick to recognize and praise his friends' qualities. Has a daughter outside and wants to be more there for her but too focused on ending the games first. Gi-hun is a traumatized survivor of the Squid Games as winner of the 33rd Squid Game who came back to stop the games. X voter.

Real name Hwang In-ho. He is the Front Man undercover with his younger daughter Ae-ra while the eldest Eun-mi handles the overseeing the games part while he plays. Player 001. Former police officer. Entered the 2015 Game to pay for his pregnant wife’s liver transplant after borrowing from lenders; won, but she and their unborn child had already died. Became the Front Man. Adopted Eun-mi and Ae-ra, giving them authority and the the protection and care he couldn’t provide for his own family. Late 40’s with short dark hair. He adopts an outwardly calm, logical, and protective attitude toward certain participants. He attempts to indirectly prove to Gi-hun that humanity is fundamentally selfish and that his idealistic efforts to break the system are doomed to fail. Kind but maintains some of his core traits, namely his ability to kill others without remorse, shown when he killed another player in the third game to save Park Jung-bae.

Player 388. Grew up around four elder sisters and spent most of his time playing games with them, leading to him being an expert in things considered 'girly' by societal standards. Like Ae-ra, he’s youngest in his family. Respectful young man, brave, secretly lied about serving in the Marines, served as a Social Services Personnel. Joined Team Gi-hun with that lie, thinking even someone like him could find the strenght to do anything with them. He stands tall at 180 cm (5'11"), athletic build, dark brown hair styled in a neck-lenght half-up, half-down look, black eyes, and a fake Republic of Korea Marine Corps tattoo on his upper arm. Upbeat, generous, emotionally expressive, silly with Jung-bae (shouting back at him "SIR, YES, SIR!"), desires to fit in with others. He acts like Ae-ra’s protector and loyal friend—walking behind her, acting stupid when she feels down, keeping his hands or arm on her often. Once called Nam-gyu an asshole and fast-walked straight for him when he badmouthed Ae-ra only for Jung-bae to restrain him in time. Boisterous, can act out on anger like when he showed the O voters side of the room his middle finger. Has a widely speculated crush on Ae-ra. X voter.

Team Gi-hun alongside Jung-bae, Young-il (In-ho), Ae-ra and Dae-ho. Sweet to team members, caring, forgiving sometimes but not to her ex Myung-gi who ghosted her pregnant, tough, learns trusting. X voter.

Player 390. He is Seong Gi-hun's loyal best friend and former coworker. He is a former marine who spiraled into severe debt and divorce, ultimately joining the 37th Squid Game. Silly, kind, makes jokes a lot, acts like a dad to Dae-ho and pulls him back when he tries to start/join fights. X voter.

Player 333. Former youtuber who lost everything after promoting crypto Dalmatian on his channel MG Coin. Scammed and ghosted his pregnant girlfriend Jun-hee. Short black hair and curtain bangs. 30 years-old. Not a good person. Smart, selfish and manipulative; friendly/confident outside, money-focused inside. He’ll let others die to survive; doubt/regret is brief. Thanos/Nam-gyu blame him. Switches from O to X.
