The Electrical Aliens (as the Seaview crew refers to them) are a sapient species of beings made of electric energy, which travel through space in tiny capsule-like vessels. They're also capable of assuming material humanoid forms. They claim to originate from the "far edge of the galaxy".
These creatures have displayed numerous psychic abilities, which include limited mind-reading, creating "heat fields" and teleporting. They're vulnerable to radiation, which can easily destroy them.

- Their humanoid form is similar to the Saticons from Lost in Space, another Irwin Allen show. However, they are a clearly distinct species.
