Jeffrey Dean Morgan will be the newest addition to The Walking Dead family, but he won’t be a welcome one. The actor is set to star as Negan, a villain from the comic series.

According to TheWrap, Morgan will likely make his debut in the season six finale and will be a series regular in season seven. In the comics, he is the leader of The Saviors, a violent group that steals food and supplies from other survivors.

As The Hollywood Reporter notes, Negan does kill Glenn (Steve Yeun) in the comics, which is why many fans think that Glenn isn’t really dead in the TV series. Negan also famously carries a baseball bat covered in barbed wire named “Lucille.”

This is the latest TV role for Morgan, who starred in Starz’s short-lived Magic City was was recently seen on CBS’ The Good Wife. Other recent roles on TV include appearances on Extant, Texas Rising and Shameless. He was also on Grey’s Anatomy from 2006 to 2009.

The Walking Dead was already renewed for season seven by AMC. You can check out our most recent recap right here.
