Hydra, from Ultima VII manual
First appearance: Ultima IV
Last appearance: Ultima VII

The hydra is a sub-species of dragons. The only thing that sets them apart is that hydrae have three heads instead of one. Otherwise, they are much the same as their dragon cousins. Amusingly, their three heads do not always have the same opinion, which experienced adventurers can use to their advantage.

First encountered in Ultima IV, Hydrae are usually found roaming through dungeons, but are sometimes seen on the surface as well.

In Ultima VII only one hydra is found, and it is shown to be fairly intelligent and capable of speech (See: Notable examples).



Beware the evil breath of the multi-headed Hydra! The massive fireballs can fry most members of thy party.

- from The History of Britannia (Ultima IV)

This creature is a type of dragon that possesses three heads. Like the dragon, a hydra can also fly and breathe fire.

- from The Book of Fellowship (Ultima VII)
