Smallville character. Human. Not very likeable.

Is hard on his son, Lex Luthor because he doesn't want him to "fail"

Likes Clark Kent more than his own son because of Clark's gifts. He keeps Clark's secret that he is a super-powered alien safe.

Almost always fighting with Jonathan Kent, Clark's father, whether it's over Clark or Lex.

Has an obsession with Kryptonite ( as he calls them: Meteor Rocks ) and every thing kryptonian.

Good at coming up with sassy comebacks.
