Cut off one head, two more shall take its place
Capable of having anywhere from 1 to 20 heads. Exceptionally large creatures, known to be quite powerful. Capable of rapid healing, dependent on its remaining heads. When one head is cut off, another two will grow to take its place, unless the stump is seared with fire or acid.
Genetics and Reproduction
Reproduces by "budding", asexually. The regenerative flesh that grows new heads will often times grow an entire new hydra.
Growth Rate & Stages
Rapidly matures from a "bud" to an adult. Grows multiple heads over time from accidents, battle, or hunger (from eating its own heads).
