Ahools are reclusive jungle predators that combine the features of a bat and an ape. They have the head, body and legs of an ape, though their feet end in vicious claws, while their arms are large bat wings with a ten foot wingspan. Their head sports a pair of bat-like ears. They can be quite vicious, but are smart enough to know when they are outclassed by another creature.
Ahool typically stalk prey from the branches of jungle trees. After they have had time to study their chosen prey, when the time is right, they swoop down in a vicious attack. Their attacks are swift, and ahool don’t do protracted battles. If they are not able to swiftly make off with their prey, they will withdraw and find a better hunting opportunity. They view just about every other species as possible prey, unless it’s too big, in which case they view it as a threat.
Ahool males are usually loners, only briefly joining a female ahool to mate. A male will warn off other males intruding into his territory, but there are rarely battles between rivals. An ahool killing another ahool is almost unheard of.
Ahool females usually form units, so that they may share the rearing of young. Upon reaching adulthood, females will typically continue on with the troop, while males go off to establish their own territory.
