 Mercurio is a native of the planet Gramos, a world threatened with extinction when a gravitational distortion blocks out all sunlight.In a bid to save Gramos, Mercurio was chosen as a government psycho-explorer to project his consciousness across the galaxy to Earth, where he takes control of a wealthy landlord and uses his resources to build a device to siphon off Earth's electro-magnetic field.Mercurio also detects strange energies coming from the offices of Dr. Donald Blake, the alter-ego of the Thunder God Thor.
