In-universe, most characters consider Wraiths to be sexually dimorphic, but it is stated within the comics that all Wraiths actually have the same form, but the males are so ashamed of their true form that they use their shapeshifting abilities to constantly appear in their transitory forms. The basic transitory form is stocky and troll-like in appearance, with red or brown skin, but otherwise roughly human-like in size and shape. The true form has an obese, reddish body with large, pupil-less eyes, small beaks, 'hands' that resemble small pincers and tentacles; clawed feet, and thick tails. They also have long, drill-like tongues, drawn to be similar to that of the cone shell mollusk, that they use to suck out the brains of their victims, allowing them to gain their memories. All Wraiths can copy the appearance of other beings without consuming their brains or killing them.
