The Tygarians are a sapient spacefaring species from the Milky Way's Alpha Quadrant which have sent expeditions to explore the Gamma Quadrant using the Bajoran Wormhole. They are reptilianoid-looking humanoids with green skin and ridge projections over the eyes extending to the sides of the head. This species has been often observed aboard station Deep Space 9. Like Humans (and unlike Klingons), they are susceptible to the tranquilizing effects of the tribbles. They are also physically similar to a Delta Quadrant species known as the Ankari, and have been observed in the Delta Quadrant themselves as members of the tsunkatse audience in the Norcadian homeworld.
