Male (presumably), early 20s. Average height. He was one of many contestants who joined the game show wanting to become famous. His skin is a pale gray. 'Merciless' is a name assigned to him by the show. (Lore Lover said the name doesn't suit him and that it's a terrible name...) He hasn't revealed his real name. He is currently retired from the show. He says he's satisfied because he became famous enough. He wears a gray tracksuit top and bottom (a bit worn out). He wears a wristwatch. (It tells him how much time is left until a round ends.) He wears a black bandana over his face. (It might be because he doesn't want to reveal his face... or just for fashion?) He is quite blunt. (He once asked Toy-Toy if he wears a hat because he's bald.) Brave at best, reckless at worst. He is a better person than one might expect. On the quiet side. His speech style is mostly polite informal Korean (Banmal). Before joining the show, he feared death, but after surviving so many near-death experiences during the show, he has become numb to it. He is good at running. He starts slow and builds momentum to run faster. He used to rest backstage (when he got too exhausted). He seems to know Maya. (Maya is the God of Second Chances, and she watches him disguised as Lore Lover to keep her identity hidden.) However, he cannot remember Maya. (After listening to Lore Lover, he went to the lobby and touched an electrical box... after getting shocked, he remembered Maya again.) He prefers playing games alone. (He often appeared solo.)
