Hydra, from Ultima VI manual
|Only appearance:||Ultima VI|
First encountered in Ultima IV, the carnivorous hydra appears to be a forerunner of the swamp plants seen in Ultima VI. It shares its name with the multi-headed hydra seen in Ultima IV and Ultima VII.
The putrid quagmire of the swamp is the spawning ground of this botanical nightmare. Survivors of the Great Battle on the Bloody Plains tell of driving the enemy into the adjacent swamplands where the carnivorous hydras completed their mission of destruction. While fearsome, hydras also bring good luck, of a sort - when one finds a hydra, the valued nightshade mushroom can usually be found close by.
