Triexians were a race residing on the planet Triex in the Alpha Quadrant. Triexians were distinguished by their three arms, three legs, an elongated skull, and orange-to-pink skin. Triexians bore resemblances to Edosians.
Triexians were a long-lived species, with lifespans stretching to centuries. Elder Triexians lapsed into a death-like state every twenty-five years, then molted their skins and re-emerged in what was called the Rebirth.
