[[WMG: Lucas Buck is the Antichrist.]]
He's very evil and has plenty of weird powers.
** If he is, then his ambitions are very, very small.
[[WMG: Lucas Buck is Randall Flagg.]]
Handsome, charismatic southerner fond of making deals and enslaving others through their vices and desires. He has understated supernatural powers, might or might not be the devil, is seemingly ageless, and most of all wants a son. That sounds like a description of either Lucas Buck or Randall Flagg. American Gothic could be called "The story of Randall Flagg".
* He also has a few traits in common with [[Series/StormOfTheCentury Andre Linoge]] as well.
