Zero Hive (inherent) Abilities
Wall Running, Bite

Wall Running: equally at ease on the ceiling as the floor, speculation is that the bladed feet of these Kharaa have retractable microscopic spines that shoot out when a spike's tip pierces a surface, and retract when the foot is lifted. This ability gives them access to vents and passage ways that, all too often, serve as shortcuts and safe-passage all over a ship or base. This also encourages ambush behavior. A Kharaa can be hiding on absolutely any surface. Never trust an empty room.

Bite: there is no Earth animal that bites like the Skulk. Super-tensile muscles are relaxed and swung open, and then tightened with incredible speed, raking its jagged teeth together. It is not trying to eat its enemies; it is trying to savage them, causing as much bleeding and damage as possible.
