1. Arch enemy of Superman.
2. The richest man in Metropolis. He could afford to buy as many cakes as he wants, yet he chose to steal forty cakes. And that's terrible.
When no one was looking, Lex Luthor took forty cakes. He took 40 cakes. That's as many as four tens. And that's terrible.

This is how it ends for the greatest criminal mind of our time. Not with a whimper, not with a bang. How do they choose to reward Lex Luthor, the greatest genius in this world? Do they give him glory? Do they give him treasure? What matter fact do they give him? Life plus twenty, Luthor! Get to work.
