The hydra is a reptilian horror with a crocodilian body and multiple heads on long, serpentine necks. A hydra is an especially deadly monster, since every time a head is severed, two new ones grow in its place giving the hydra not only more attacks, but also seeming to heal it slightly with every regeneration.
Hydras have an everlasting hunger. They are gluttonous monsters that will hunt their territory bare. It will then move onto the next spot to rend and consume the flesh of every living creature it can find. As amphibious creatures, hydras have a lot of different potential hunting grounds. They are tough creatures that can shrug off nasty weather with little effort. Only in cold climates will a hydra seek shelter from the elements.
While a hydra is asleep at least one of its heads will stay awake to look-out for potential prey that may cross its path. There isn’t much that a hydra would consider a potential predator, but should one cross its path they’ll have a hard time ambushing a hydra. Hydras are extremely perceptive thanks to their multiple, ever-watching heads.
On the positive, hydras seem particularly sensitive to fire which has been used to interfere with the additional heads regenerating during an encounter.
