The governments of many countries experimented constantly with new technology in order to make their soldiers better.

One of the experiments involved working with a formula which would allow a soldier to become utterly invisible to the naked eye. This was first tested on lab animals, specifically monkeys and apes to see how the serum would work. Unfortunately for the primates involved, it worked but it had a unexpected side effect.

The transformation from visible to invisible was incredibly painful for the test subject. It nearly drove the unfortunate primate insane, and thankfully the scientists were capable of reversing the process.

The final wars occurred and many of these test primates escaped or were let go by the scientists, hoping they would have a chance to survive in the post-apocalyptic environment.

The species flourished, but they also discovered something horrible had occurred. Many of the creatures were exposed to radiation and it mutated their already altered genes, causing them to become invisible.

The process was painful at first, but only got worse when they became fully invisible. The pain was so bad that they would lash out at anything they could get their paws on. These apes discovered that by eating the flesh of still-living creatures, it eased the pain and would reverse the transformation.

Once the creature is fully invisible, it will actively seek out anything it can find. Despite the pain it is feeling from the transformation, it will remain utterly silent and as such will wait in ambush or simply track down individuals and attack. It will gain surprise on a 1-3 as a result.

It will attack by smashing its fists and then biting the target. For every 10 hit points of damage it inflicts with its bite, it will begin to become visible, starting with the nervous system, circulatory system, skeleton, organs, muscles, and finally skin and fur. Once it has become fully visible, the creature will then cease its attack and flee; having finally freed itself from the pain it was suffering.

The creature will remain visible for only 1d4 days. It will then begin the slow process of becoming invisible once again, going in reverse order, losing one layer every 24 hours unless it consumes at least 10 hit points of flesh from any living creature. It has to be eaten directly from the body of a still-living creature or the flesh will have no effect.

As the creature loses more and more, revealing its internal organs and so forth, those viewing the monster must make a saving throw versus energy or become fearful, suffering a -2 to hit and saving throws. If the roll is a natural 1, the viewer must run as fast and as far as they can to escape, moving at their best movement rate.

When sated and fully visible, the creatures will not harm or bother anyone, relying on their hunting skills to track down small animals and birds to keep the invisibility at bay.

They do live together in small family groups, usually a mated pair with their offspring. The small troupe will work together to encircle prey, or even use one or more members of the family to scare and chase prey into an ambush.

Mutations: control light waves (modified), dietary requirement change (living flesh)
