Superboy is using a Kryptonian "thought helmet" to receive a mental history lesson about some of Krypton's greatest criminals:
Yes, in Zod's very first appearance, he tried to use an army of "imperfect duplicates" of himself to take over Krypton. Because an army of dummies with a poor grasp of grammar is a wonderful way to overthrow a super-science society. "Me want to overthrow Krypton" indeed!!
And, as he gets banished into the Phantom Zone for the stupidest coup plot ever, enjoy his uncomfortably tight shorts:
So, what I'm saying is, I really hope this is the Zod we get for the new Superman movie: Viggo Mortensen* as a buffoon in tight shorts who creates a ton of imperfect imitations of himself because that's the best way he could think of to conquer Krypton.
Because nobody said Zod had to be smart...ruthless and evil, sure, but not smart.
*(Editor's note: yeah, we just read that Viggo is not actually going to be in Superman: Man Of Steel. But it's late, snell is tired, and there's no way he's going to go back and re-write anything at this point. Please feel free to insert your own favorite actor into the Zod role.)
