The Hath

Home Planet: Unknown/Messaline?
Life Form: Piscene Humanoids

The Hath were a humanoid race with purpley-orange fish-like skin and a small headcrest running along the top of their heads. They were slightly taller than most near-humans. They breathed nutrient liquid rather then air and so when in a human-breathable atmosphere they used a breathing instrument attached to their mouth. Just like the humans, the Hath used Progenation chambers and generation chambers to produce more soldiers for the war between the humans and the Hath, even though they had once been allies. However, with the death of the mission commander, there was a power vacuum and both species fought to take the planet for their own. The Hath carried heavy duty blaster rifles that fired a barrage of bullets usually accompanied by a long plume of flames emmited from the barrel of the gun. The humans carried guns with the same overall effect but with a different design. They breathed and communicated, using their breathing structures on their faces. They also had the same holographic mapping system as the humans and when the Doctor uncovered the suppressed layer of information it showed up on the Hath map as well. After a seven-day battle, the two races found the "Source", an artefact that mythologisation had led them to believe was the breath of the creator. Due to the efforts of the Doctor, Jenny, Donna Noble and Martha Jones, the Source was broken and terraforming gases within escaped, and the two races were to peace.
