The Marquess of Queensberry is a main character in Mike Tyson Mysteries. Marquess (Pronounced "Marcus") is based off of John Douglas, the 9th Marquess of Queensberry.

Marquess is seen as the level-headed member of the group, often giving Mike Tyson advice about his life or current situation. His naïvety and honest nature often bring him at odds with Pigeon. It has been shown he smokes and has tried to quit but failed multiple times.

Origins and PersonalityEdit

It appears he shows no sign of trying to stop smoking since he pointed out "I'm a ghost, I can't get cancer." Douglas was also quite influential in the Oscar Wilde Trials. Supposedly Wilde had a sexual relationship with his son Alfred. This may explain to allusions to his homosexuality on the show. It is also worth noting that the real life John Douglas was Scottish and had a Scottish accent unlike in the show.

The real Marquess of Queensberry is notably famous for endorsing the "Queensberry Rules" upon which modern boxing is based. John Douglas was supposedly a pugilist and boxing enthusiast, which would explain his presence with ex-boxer Mike Tyson.


  • He is Jewish.
  • He is the ghost of John Douglas, 9th Marquess of Queensberry.
