Lex Luthor, Superman's archenemy
Lex Luthor is the owner of a corporation called LexCorp, power-mad billionaire, business tycoon, inventor, philanthropist to the city of Metropolis, and one of the most intelligent people in the world. A charismatic and well-known public figure, he is intent on ridding the world of Superman, who Lex Luthor views as an obstacle to his megalomaniacal plans and as a threat to the very existence of humanity. He was describe like an amoral, sociopathic predator, driven by jealousy, greed and a grandiose self-delusion. I agree with both descriptions.:)
Lex Luthor quotes :
"There's a strong streak of good in you, Superman. But then nobody's perfect... almost nobody."
"Do you know why the number two hundred is so vitally descriptive to both you and me? It's your weight and my I.Q"

I tried to make a Lex Luthor in suit of CEO. It's a really simple mix : I've used the body of the Joker from DC Collectible Designer Capullo series with head and hands from DC Direct Superman Silver Age Lex Luthor. I retooled the neck et repainted it.
It was a very quick job. I hope you like.
