From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Atla (アトラ, Atora; FUNimation "Atla") is an Arlian.
Atla was one of several Arlians who had been imprisoned by the cruel King Moai prior to the arrival of Vegeta and Nappa to Planet Arlia. Upon his imprisonment, Atla's wife, Lemuria, was claimed by Moai and crowned queen, however, Lemuria continued to resent the king for separating her from her lover. After Vegeta and Nappa launched their attack on Moai's civilization, which left the king and his guard in shambles, Atla was reunited with Lemuria. Their reunion was cut short, however, when Vegeta and Nappa, now outside of the orbit of Planet Arlia, sent a Finger Galick Gun into Planet Arlia and destroyed the planet.
