They are humanoid creatures with insectoid exoskeletons and long tails which sport sharp sickle-like blades, which are used for surprise attacks. The Verdugo's exoskeleton is almost completely bullet-proof, but is weakened by exposure to liquid nitrogen, and while frozen it is more vulnerable to weapons fire and explosives, and will be shattered into pieces if hit with sufficient force.
The Verdugo possess keen agility and exceptional combat capabilities. The second Verdugo merges with Salazar, along with a mutated plant. This Verdugo forms the large snake-like head of the merged entity.
