ASP-??? Lanky Men In Black Thing:

The Lanky Men In Black Things are tall, slim men with waxy, pale skin wearing dark suits and fedora hats. While being almost 7 feet tall, this ASP has thin legs and arms, and their waists are around the size of an adult males thigh. These creatures have lifeless eyes. They can sync their movements, even through they look to have trouble walking or even standing upright with a disorderly gait. They also have the ability to stay perfectly still, even with the previous statement. They work with humans, or are humans with wildly differing characteristics. They look like - or are - corpses.
