Chupacabras are small, badger-like humanoids that live by drinking blood. They are not undead, despite rumors to the contrary. They roam rural areas and abandoned or derelict sections of major cities, seeking warm-blooded prey to feed on.

Chupacabras are bipedal, with large red eyes set in a rat-like skull. Their mouths can open very wide, revealing saber-like incisors and a hollow proboscis instead of a tongue. They are covered with stiff fur, usually black or dark brown, and have a thick matting of long, porcupine-like quills running from the base of the skull all the way down the back. These quills are defensive in nature; any creature attempting a hand-to-hand attack against a chupacabra from behind (for example, while the creature is feeding) must make a Reflex save vs DC 25 to avoid taking 1d6 damage from the quills.

Chupacabras can leap amazing distances, and are often believed to be able to fly because of this. Horizontal leaps of 25' are common, and 15' vertical leaps have been seen, both from a standing start. Chupacabras move like kangaroos, in a series of two-footed hops when running. Their three-toed feet have ridges on the pads for additional traction. Their hands also have three fingers, each with a hook-like claw. In combat, they will attempt to swarm an opponent and overbear them. If a chupacabra hits with both claw attacks, they will cling and do an automatic 1d4 additional damage each round unless removed (opposed STR check). While clinging to a target, the target loses all DEX or class-related DC bonuses; only actual armor worn is counted.

The bite of a chupacabra is septic and its saliva contains a powerful anti-coagulant. Each bite wound will continue to bleed for 1 hp damage each round until bandaged or magical healing is applied. A chupacabra victim must make a Fortitude save, DC 20, or be infected with a blood-born infection (DC 20 Fort save each day or lose 1d3 CON points. If CON reaches 0, the character dies. Remove disease cures normally). The proboscis does not have an attack; it is used only to suck up blood through the wounds inflicted by the canines.

The fur of the chupacabra is very thick and stiff; most blows and small arms fire are simply deflected by its pelt. This gives the creature 10 points of damage reduction to attacks that are not a magical +1 to hit or better.
