|This article is about a/an species in Power Rangers S.P.D.|
Females have shorter ears than males. Sirian skin color ranges from dark blue to purple to red. Despite the fact they speak like Humans do, they make dog-like growls when frustrated. While they seem like humanoid canines in appearance, Sirians also have scaly skin similar to an Earth reptile on parts of thier bodies with some having dreadlocks of tendril-like hair on thier heads.
They were the first species to have the very first S.P.D. One of it's most notable members is Anubis Cruger, who fought Emperor Gruumm, leader of the Troobian Empire when they invaded Sirius. Although he severed one of his horns, the Troobians destroyed Sirius, leaving Cruger the only known survivor, although it was revealed his wife survived too.
Cruger was the head of the Space Patrol Delta Earth Base during the early 2020s, and S.P.D. Shadow Ranger. A little while after the failed Troobian Invasion and the defeat of Emperor Gruumm and Omni, he became the Supreme Commander of S.P.D.
