Serpens: I am Serpens, one of the heads of this great Hydra. I am always ready to strike at any who would threaten our existence. Together with my siblings, we are a force to be reckoned with. Cerastes: As a member of this mighty Hydra, I am Cerastes, a head among many. We are a creature of many minds. Every head you chop off, two new heads will grow in it's place. Mineral: I am Mineral. We are three heads of a hydra, we think independently.
