Galexia is a being of cosmic & electric origin. Scientists at this point do not know much more. She has been known to swoop into areas of space, disrupting satellite signals in her wake. She is able to penetrate spaceship shields and wreak havoc on the electrical systems. She always leaves things as she found them though and never harms anyone. She more or less messes with electrical systems because she finds it humorous to see the people frantic to fix them, and because it is her only way to communicate with humans or other beings.
There is some speculation that Galexia was once a human female that was hiking in a very remote region of the Siberian forest. She was then caught in a historically epic thunderstorm, that was immediately proceeded by an aurora borealis effect in the sky. Again, leaving scientists completely befuddled.
Reports to the authorities were made, as this hiker was never seen again. Something strange is rumored to have occurred that night resulting in Galexia as we know her now. But these are mere speculations. For now, she roams the universe messing with humans and other planet dwelling beings' electrical systems or, just popping up in the horizon of a planet and staring at the inhabitants.
