They have three sexes and breathe methane. They generally inhabit the type of planets that other races avoid.

Despite their odd appearance, Hydrans are almost human in terms of their philosophy and disposition. In general, they don't attack unless provoked, and are more interested in scientific exploration than territorial expansion.

They have two heavy weapons, the Hellbore and the Fusion Beam. Fusion beams are very short ranged. Hellbores can envelope the shields of the target, doing the most damage to the weakest shield.

Most ships of the Kingdom are also equipped with small fighter-craft. Hydrans rely heavily on their fighters.
