An energy being or astral being is a theoretical life form that is composed of energy rather than matter. They appear in myths/legends, paranormal/UFO accounts, and in various works of speculative fiction.
Energy beings are typically rendered as a translucent glowing fluid or as a collection of flames or electrical sparks or bolts; somewhat in common with the representations of ghosts.
Energy beings have a variety of capacities. The Taelons (from Earth: Final Conflict) are barely more powerful than mortals, while others such as Star Trek's Q, Stargate SG-1's Ascended Ancients/Ori, Ben 10: Alien Force's Anodites, or the Meekrob from Invader Zim possess god-like powers.

He can repair damaged tissue in a form of resurrection, and he can also project an image of the Universe into a human mind and make them comprehend the immensity of space-time. His home galaxy is the Andromeda Galaxy, thus placing him in this category.
