Alien Wraith

Background
The Wraith is a long-feared species within the universe. Their whereabouts and their origin are unknown, and nobody has ever known what they are or what they all look like. All Wraiths start off the same, Silent. These Silent Wraiths can then go on to become dozens of other types of Wraiths. Some appear to be ghosts, while others have the appearance of humanoid warriors.

Characteristics
Adult Alien Wraiths are mindless monsters developed from regular Wraiths. They are extremely quick and can run faster than any land-vehicle made by humans. They are somewhat humanoid, with large heads and spindly bodies. Despite their scrawny looks, Alien Wraiths can carry large weights and throw projectiles weighing up to 150 kilograms. They have long fingers that can reach up to 20 centimetres long, with each of these fingers having a sharp tip on the ends of them.

Unlike all other Wraiths, Alien ones can lay eggs. Alien Wraiths make large nests underground to raise their young. However, they the eggs do not hatch baby Alien Wraiths, they hatch regular Wraiths. This reproduction boosts the number of regular Wraiths formed each year, thus increasing the amount of all other Wraiths as well.

Attacks
Alien Wraiths use their extremely long fingers as weapons. The sharp ends act as claws or mini-knives. They are very unintelligent, making their battle tactics very erratic and unpredictable.
