Hydras and Chaos Hydras are the level 7 creatures of Fortress. They are recruited from the Hydra Pond.

"Hydras and chaos hydras are multiheaded serpents attacking with vicious bites. When they attack, they attack all adjacent enemy troops. This attack is so overwhelming no counterstrike is possible." ^{RoE manual}

Hydras and Chaos Hydras, as well as Sea Serpents, Haspids , Couatls, Crimson Couatls  and all living Dragons, can be transformed into Bone Dragons at a Skeleton Transformer.

Neither Hydras nor Chaos Hydras have any immunities, and they are the slowest level 7 creatures in the game. But when the hero has expert teleport, the Hydras and Chaos Hydras are excellent at siege warfare; teleport them behind walls and they will wreak major havoc on enemy troops. Counterstrike is devastating if the enemy surrounds them; each time they attack or counterattack, they damage all enemy troops around them. Hydras and Chaos Hydras are generally regarded among the worst 7th level creatures, serving only as a relatively strong defensive unit and guard for Ranged attack type units. In addition to their slow speed and lack of ranged attack or flight, their strongest ability - attacking multiple foes without retaliation - typically depends on opponents choosing to surround the hydra with melee attackers. While this can be devastating when the right battle is fought, more often than not your Hydras and Chaos Hydras will be outpaced, outshot, tied down with spells and tangled up in obstacles for the majority of the battle. They also bear the lowest minimal damage for a tier 7 unit, sharing this stat with the Bone and Ghost Dragons. Combat strategy tip A few chaos hydras defending a castle is about the best overall defense-for-cost strategy in the game. If you have a hero that can cast fire shield, counterstrike, shield, or anti-magic you can potentially defend a Fortress Town against an attacking army many times more formidable. Leave your hydras to defend and send your primary hero out with creatures level 1-6 If a Hydra attacks multiple creatures with a Fire Shield (e.g. from Ironfist of the Ogre ), they get the damage from all Fire Shields.
