Your arch nemesis at work. A person that opposes everything you represent, and does nothing besides make your life miserable.

A person who is your friend, but at the same time, is your worst enemy (as Lex Luthor is to Clark Kent of 'Superman' and 'Smallville' fame).

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.
