Seong Gi-hun, the closest thing the show has to a hero, is No. 456. Crafty Cho Sang-woo, the pride of his hometown, is No. 218. Elderly Oh Il-nam is No. 001, scrappy North Korean defector Kang Sae-byeok is No. 067, and brutal gangster Jang Deok-su is No. 101 — for him, you’ll want to get your artist friend to draw a snake tattoo on your face.
