Kribleen Insectoid Vampire

Kribleen Insectoid Vampires are a sapient alien species hailing from the Gluubux Galaxy.

Biology
They're humanoid insect-like creatures with a sharp proboscis used to perforate their prey and feed on their blood like a mosquito.

Culture and society
Virtually nothing is known about this species. It appears that their homeworld isn't such a good place to live, judging by how Mosquitor willingly joined the ranks of the Evil Horde to avoid "life in a mud hole on his home world".
