Hydra breathe a potent poison, and their entire bodies are filled with it. Simply standing near an adult one will make a human's lungs begin to rot. Even a deceased juvenile is great enough to harm someone with direct contact, and though not enough to kill a Servant, could still prove harmful to one. Being poisoned was not enough to kill a Divine Spirit like Chiron, but the constant pain was enough to make him give up his Divinity and immortality to cease his torment.
Hydra's Saint Graph Designation can be Rider and Archer in Fate/Grand Order.

===Juvenile Hydra===
Rocco Belfaban owns a juvenile Hydra preserved in formalin, a small snake with its head split in nine. It is a one-of-a-kind item in the entire world according to Kairi Sisigou, and even one-third of its selling price would surpass his house's combined estate. He is able to process it into a potent poison for use in the Great Holy Grail War.
===Casa Hydra===
During the third and last game of Fem's Casa, Magique, a Hydra is one of the monsters faced by Rin Tohsaka and Luviagelita Edelfelt in the gladiator arena.The Adventures of Lord El-Melloi II Volume 8: Fem's Casa (Lower) - Chapter 5 Like the other creatures in the game, it's not a real Phantasmal Beast, but a dummy replica created with Van-Fem's know-how.The Adventures of Lord El-Melloi II Volume 8: Fem's Casa (Lower) - Chapter 2
Gandr doesn't work on the creature and it overwhelms the two magi by being coordinated like a football team, with three heads playing forward, three playing midfielders, and three as an immovable defense. It has regeneration as fast as Dead Apostles' and its heads can entangle and merge into one much greater head to overpower the opposition. Furthermore, the Hydra can move beneath the sand of the arena by using its venomous breath to melt the dirt and swim through it as it liquefies, turning parts of the arena into a toxic swamp where only it can move freely and slowly encroaching the surface area the girls can stand on.
