Arlians were an insectoid species from planet Arlia. The planet and the race only appear in the filler episode "Terror on Arlia", not in the original manga. However a member of the race does appear in the Resurrection ‘F’ manga adaptation.
All of Moai's guards can shoot laser beams from their mouths, and were swordsmen. They are also seen riding giant Worms. Ironically, the Saiyans were celebrated as heroes to the Arlians after killing their evil dictator, King Moai, unintentionally freeing the oppressed before they decided that the planet was in too poor of a condition to bring in any good profit and vaporizing it.
An Arlian appears amongst Frieza's army of 1,000 soldiers in the Dragon Ball Z: Resurrection ‘F’ (manga). It could be due to their race being revived due to the wish to revive all of Frieza & his minions' victims, and at some point later they might have gotten conquered by the Frieza Force which exploit their manpower. Alternatively Arlia was not destroyed by Vegeta in the manga's continuity as the planet's destruction by Vegeta in the anime was Filler and presumably Arlia was conquered at some point by the Frieza Force.
