AMC this morning released a teaser image of The Walking Dead bad guy of bad guys Negan, played by Jeffrey Dean Morgan. The anticipated series debut of the villain from Robert Kirkman’s graphic novels is set for Sunday during zombie apocalypse drama’s Season 6 finale.

The image shows the back of Negan’s head along with his weapon of choice: “Lucille,” a baseball bat wrapped in barbed wire.

Rumors of Negan’s addition to the hit TV series had been swirling since its start before Morgan landed the role in November. His eventual debut has been part of a buildup all season, with executive producer Gale Anne Hurd telling Deadline at one point, “Let me put it this way. He’s worth waiting for.”

Check out the teaser:
