Skin-Suits

The disguses are made from the reminats of dead peoples bodies.

Making a Skin-Suit
The Slitheen teleport, if they have not disguised yet, or unmask, if they have already disguised. When they are in their natural form they use their massive green arms to strangle and kill their victim. Once they are dead, the Slitheen skin them (we do not know what happens to the inside of the body). They then use the skin as a suit to wear. Then add an invisible zipper to the dead skin so they can get in and out of the suit. The disadventages are that the skins will only fit people who are overweight and it produces a gas exchange problem that has been corrected with the newer suits.
