You can check out the previous installments of this rather lengthy series here.
This is the second part of Superman vs. Huge Robot Mummy, which had superman getting knocked out by a giant robot discovered in an excavation in South America. And this is not your typical Science-powered robot – it contains the souls of 500 members of an advanced race that lived on Earth half a million years ago, and every single one of them is a jerk.
Most of the jerks left the planet when germs started killing them, but a bunch stuck around by putting their souls inside the robot and burying it deep. Isn’t that the plot of a John Travolta film or something?
