Albarian

The Albarians were a humanoid race native to the planet Albar in the Twelve Galaxies. Though they were externally identical to humans, Angstrom was unfamiliar with the planet Earth and human beings, calling them "Moomenbeans".

Half of the Albarian race were "systematically cleansed" by the Stenza after they invaded Albar, which motivated Angstrom's part in the Rally of the Twelve Galaxies. (TV: The Ghost Monument)
