The Numbers are comparable in size to giants, utterly dwarfing humans and longarms like Scratchmen Apoo. They all possess two horns on their head, much like Kaido, and two of them carry a spiked club similar to Kaido's kanabo, thus giving them traits similar to those of the legendary oni. Two of them have been shown with very sharp teeth. Their physical constitutions vary greatly, with some being taller and slimmer while others are shorter and rounder. One member has a notably long neck.
According to Queen, every member of the Numbers has a drinking problem. A child from Hakumai told another child that they would be eaten by the Numbers if spotted, but it is unknown whether that is the truth or a myth. Likewise, he also said that they were from Onigashima, but it is unclear whether he meant that they were native beings of Onigashima or that they were members of the Beast Pirates who are situated in Onigashima, hence stating that they were from there.
