He's already got a tough fight against his critics in the final season of Amish Mafia, but the biggest threat to Lebanon Levi's empire could be something much greater.

Meet The Newest Members Of The 'Amish Mafia' Cast

A rogue group of Mennonites, led by two rebels named Doug and Zach, will pose a serious new threat to Levi, as they attempt to not only take over, but take complete control of the Amish-controlled Lancaster County.

'Lancaster might be the home of the Amish now, but when I'm done with it, it's going to be the home of the Mennonites," Doug says in a preview clip for the season.

He definitely appears to mean business as well with his threats, as he and Zach load up guns and participate in major shoot-outs, set up a few different explosions, and even back a car into a horse-and-buggy and knock it to the ground in an apparently violent attack.

"Hopefully this sends a message," Doug adds. "Don't mess with us. This is a show of force. I want Levi to understand that he's not safe, anywhere."

However, Levi won't take their attacks without fighting back on his own-and will make sure they don't have the ability to take over the territory he has worked so hard to retain control over.

"I have to go find these Mennonites. It's war," he says.

However, Levi's retaliation will only enrage his newest enemies even more-and the battle could get even more ugly.

"I want every one of them taken out," Doug screams in the clip.

Amish Mafia the final season premieres Feb. 10 at 10 p.m. on Discovery.
