After the series Crisis on Infinite Earths, John Byrne's Superman revamp re-introduced the Man of Steel and his world in a new continuity, pressing the restart button, if you will. Byrne and/or Marv Wolfman (accounts vary) reenvisioned perrenial Superman foe Lex Luthor as the wealthiest, most respected businessman in Metropolis. I liked this direction, and it worked well for almost two decades, culminating in Luthor achieving the ultimate position of power: the Presidency.
Well, that's about as far as DC could really go with the untouchable businessman routine, which is why I'm glad to see him back in full fledged "mad scientist" mode again in this weeks Superman# 653.
GO LEX, GO!
