The Twins appear as two short children, wearing sacks on their heads that have holes for the eyes, thick triangular eyelines with some makeup on them, and small black lips as the design for the mask. For their outfit they wear white baggy shirts with white shorts and white stockings and shoes.
Not much is known about the Twin's personalities, besides the fact that they are shy and quiet due to the fact that they do not speak to anyone besides each other. The twins also are very affectionate and attached to each other, as they are always together, and they only talk to each other.
In the movie, they are often seen communicating via incoherent snarls.
Not too much is known about their peculiarity, but in the movie they were capable of turning a Wight into stone with just a glare, similar to Medusa in Greek Mythology. It was believed in the book they had a telepathic bond.
- The two may be considered as close friends of Abraham, considering the fact that he kept a photo of them with him in America.
- The pair are the first and only characters so far to have two actual pictures of them in the series. Other photos only show people who resemble the character rather than of the same people.
