Tirolians, sometimes called Tiresians (after the largest city on Tirol) were a humanoid race native to Tirol, a moon of the planet Fantoma. Tirolians are nearly identical to humans from Earth, save for a handful of cosmetic differences in hair, skin, and eye colors. The triumvirous Robotech Masters evolved from the Tirolians while in search of immortality and a perfect race. The clone Masters were notoriously harmful to the natural-born citizens of the planet, even leaving them as bait for the Invid as they ran for Earth. (Robotech II: The Sentinels, Robotech II: The Sentinels)
The Robotech Master's experiments in Tirolian physiology and cloning also led to the further development of the Zentraedi race.
