The unnamed Mob boss is the overarching antagonist of the 1997 film Home Alone 3.
He was portrayed by James Saito who also portrayed Shredder in the 1990 live-action adaption of Teenage Mutant Ninja Turtles.
The mob boss formulates a mission to retrieve US$10 million missile cloaking computer chip, which would be used in North Korea. He hires a number of participants, one of them being internationally wanted criminal Petr Beaupre.
With the help of recruits Alice Ribbons, Earl Unger, and Burton Jernigan, Beaupre manages to acquire the chip from a contact in Silicon Valley. While they successfully steal it and hide it in a remote control toy car so they can pass airport security, they lose the chip to Mrs. Hess, who accidentally takes the bag that carries the car, thanks to a luggage mix-up caused by extra screening procedures.
The criminals follow Mrs. Hess to Chicago, where they later realize that Alex Pruitt has the car. The mob boss calls Beaupre and tells him if he doesn't have the chip in 24 hours, the mission will be terminated. The mob boss doesn't appear again and it's unknown if he was arrested or not.
- The mob boss is the first character to hire associates to steal something.
- Not much is known of him such as the date of his birth or citizenship but it is implied he hails from the Democratic People's Republic of Korea (commonly known as North Korea) or the People's Republic of China by the following reasons:
- The FBI and other authorities state in the film that the four criminals hired to steal the microchip work for a North Korean terrorist organization
- It is implied the mob boss is a high-ranking member of the organization, disguised as a Hong Kong-based South Korean businessman.
- The IMDb profile for the film credits him as "Chinese Mob Boss".
- Although the character is implied to be a North Korean, he was portrayed by James Saito, who is of Japanese descent
- Beaupre and his team's arrest by the police can be viewed as a lesser punishment, as the mob boss had previously threatened Petr that if the chip is not in his possession within twenty-four hours, he would abort the mission and tie up all the loose ends - in other words, send someone (possibly even another team of mercenaries) to kill them for their failure.
