Do you know the destiny of Superboy Prime?
The secret inspiration of the 30th centuries Legion of Super villains?
He melted half the extended ranks of the Teen Titans with a single strafe of heat vision and murdered in a fair fight about 80 Green Lanterns. He's a deush.
Plenty of Supermen go bad.
There was a delightful "what if" story written a couple years back by Mark Millar called "Red Son" about what would have happened if Clark's rocket ship had made earthfall in communist Russia during the 1930s. Sure he wasn't evil, but believing that Joseph Stalin was a good man is not a good place to start.
Right now, I'm expecting this Clark to go bad.
The final episode is Clark taking over the world. Everyone capitulates. Jor-El degrees that he is proud of his son, and then Chloe opens a portal to a parallel Earth where from a more recognizable Superman steps through to save the day.
