As fans of the FX-adapted Elmore Leonard series 'Justified' well know, the show would be nothing without its iconic villains, from Boyd Crowder to Mags Bennett, even the more recent city slicker Robert Quarles.  So with the show poised to head into its fourth season next year, who could possibly take the reigns as Harlan's next big bad?  Will it be someone close to Raylan Givens' own heart, or someone new?

While 'Sons of Anarchy' might return tonight, 'Justified' fans patiently await news of FX's other gun-slinging thriller, set to return sometime in 2013.  After 'Justified' season 4 saw city-slicker big-bad Robert Quarles (Neal McDonough) put to rest, fans have been wondering what new threats Raylan Givens (Timothy Olyphant) and the Harlan police department might face in the coming season.

Thankfully, TVLine managed to drop an outline of a few new characters to be seen in 'Justified' season 4 via Ask Ausiello, teasing:

The FX western is recruiting a new batch of freaks for Season 4, and they include a rule-bending military police sergeant who shares a past with Boyd, a fugitive family man who teams up with a pair of drug addicts, a local Constable who went to high school with Raylan, and a charismatic young preacher who starts cutting into Boyd’s profits.

It certainly seems like Boyd Crowder (Walton Goggins) will have his plate full when 'Justified' premieres its fourth season in 2013, but what do you think?  Who might the FX gunslinger bring in to fill said roles?  Will they prove to be big bads or minor villains?  Tell us how you'd like to see 'Justified' season 4 play out in the comments below!
