The Hydra is from Greek mythology and was an offspring of Echidna and Typhon. The hydra is a many-headed serpentine creature. The number of heads a hydra has varies from 5 up to hundred. Nine head is the most common amount that hydras are usually given. One of the heads of the hydra cannot be harmed at all by any weapon. If any of the other heads that were cut off would grow back. Sometimes some of the Hydras heads can breathe fire. The teeth from a hydra are meant to have magical properties and it is said that a hydras teeth can raise skeletons from beyond the grave.
