Ghoul (Piratez)

Ufopedia Text: "These despicable creatures suffer the horrible Necron disease. The full enviro suits they wear protect both themselves from the surroundings, and vice versa. They sometimes conduct 'harvest' raids to replace their falling organs with fresh ones, taken from their victims. They live in small communities, known for their medical and chemical knowledge. The disease they suffer, apart from disfiguration, decay and horrible smell, gives them also some unique feats - like the ability to regenerate lost health during the battle, at a cost of a major strain to their bodies. In general, they're slow, but quite dangerous enemies - they're immune to fire, acid and smoke, and resistant to stun, laser and concussion. Better to kill them fast to avoid trouble."
