Hydra

Hydras were a breed of reptilian magical beast that had anywhere from five to twelve heads.

Ecology
Hydras typically lived alone in fetid swamps and waterways and were generally always the most dangerous predator in whatever area they inhabited.

Combat
A hydra was an especially deadly monster, since every time a head was severed, two new ones grew in its place.

Behavior
A hydra was not very intelligent, about as much so as an animal. Hydras were usually neutral in alignment.
