a Pleaidian (also known as "Nordic" aliens) are a type of alien from UFO folklore, conspiracy theories and New Age movements.
They are depicted as strikingly human-like in appearance, often with brilliant blue eyes and golden hair (though they can easily alter their form due to advanced spiritual and technological capabilities).
Unlike many other aliens they are seen as benevolent and are often referred to as "Space Brothers", with some believing them to be a type of human who left Earth in the ancient past and took to the stars, they are believed to be trying to aid humanity in ascending to new levels of civilization and are traditionally opposed by the Reptoids and Greys.
