1. Chupacabra

In the mid 1990s in Puerto Rico, livestock were killed and appeared to have been drained of blood through puncture wounds to their necks. Eyewitnesses claim the creature responsible for the killings was an ugly creature that stood like a kangaroo with spikes running down its back, large fangs protruding from its mouth and large, predatory eyes glowing red. The case went cold until similar attacks by a different creature occur in Texas, and ranchers and farmers discovered the remains of this weird creature.
