List of Squid Game characters

Hwang Jun-ho is portrayed by Wi Ha-joon.

Jun-ho is a South Korean police detective who is searching for his missing half-brother, In-ho. When Seong Gi-hun (Lee Jung-jae) explains his experience in the first game to the police, Jun-ho is the only one who does not react with skepticism. He later discovers evidence that his long-missing brother took part in the games, after finding the same Squid Game business card Gi-hun left at the police station in his brother's abandoned apartment room, so decides to infiltrate the games to try to find him.

Jun-ho stows away on a ferry to the island where the games occur and poses as a guard. He records several events from the games on his cell phone with the intent of delivering this evidence to his skeptical boss and colleagues. After a higher-level guard is killed, Jun-ho takes his place and discreetly asks Gi-hun if he has heard of a player named In-ho. Gi-hun responds by saying the players do not know each other's real names.

He later gets caught up in an organ trafficking plot which the guard he initially took the identity of was part of, and believes his brother died in the games as the corrupt guards who were trafficking player's organs mentioned a player acting like a 'zombie' with only one kidney. Jun-ho believed this was his brother as he had previously given Jun-ho one of his kidneys. Although this was just a coincidence, Jun-ho shoots one of the guards, Number 28, dead in a fit of rage.

Jun-ho manages to sneak into the Front Man (played by Lee Byung-hun)'s office room on the island, where he discovers a vast archive of past players and winners and is surprised to find out that his brother won the games in 2015. He narrowly avoids being found by the Front Man and disguises himself as a waiter to the sadistic VIPs who watch and bet on the games. He ends up being sexually assaulted by one of them, and uses the opportunity to take him to a private room and force him at gunpoint to reveal everything he knows about the games on camera. He leaves the VIP unconscious and attempts to flee the island, convinced he has all the evidence he needs, briefly being spotted by the Front Man as he leaves.

The Front Man and the guards ultimately corner Jun-ho on a cliff, where Jun-ho identifies himself as a police officer and says that he has sent evidence of the games to his superior, despite there being no signal on the island. The Front Man is skeptical and offers to spare Jun-ho if he hands over his phone and gun and deletes the evidence. Jun-ho responds by shooting him in the shoulder and demanding to know who he is. The Front Man then removes his mask and reveals himself as his brother, In-ho. He again offers to save Jun-ho, but he refuses and In-ho aims his gun at his brother who asks, "In-ho…why?" In-ho shoots him in the shoulder, causing him to fall off the cliff and into the ocean. Later, In-ho is shown to be haunted by his brother's last words to him.

Jun-ho survives his fall off the cliff, being saved by Captain Park, a fisherman. Jun-ho, with Captain Park, has been searching for the game island for two years, without success. He has given up his job investigating major crimes and became a traffic police officer, leading him to investigate and find Gi-hun. The two talk and team up to end the game for good, as Jun-ho's superiors at the police station still do not believe the Squid Games exist due to lack of evidence. Jun-ho, along with Choi Woo-Seok, who has formed a team of mercenaries, hatch a plan to catch the Front Man. The plan fails and they plan to track Gi-hun to the game island with the tracker they implanted in him, but it is stolen from Gi-hun and they lose track of him. Jun-ho and the team search different islands. On one of them, they see a possible entrance, but it explodes when they open it. Back on the boat, Jun-ho refuses to go back until he finds the island, although Captain Park turns out to be an infiltrator and sabotages them numerous times. Provided by Wikipedia
