white creature with red veins running  along the sides of its head. It had an inner jaw, similar to the all  the other aliens. It also had a pair of pincers on the sides of his  head. These pincers were used to hold its prey still as it drained  the prey of blood with its inner jaw. The creature was also larger,  nearly the size of the queen alien. In later script revisions, the  creature was changed into a "more believable" hybrid of human and  alien.
