In Sunday's highly anticipated 90-minute finale, the graphic novel villain and his trusty barbed wire-covered bat, Lucille,
will finally come face-to-face with the audience, and according to Negan himself, Jeffrey Dean Morgan
, it's going to be the most talked-about TV moment of all-time!
"I don’t know if the fans are going to be ready for it, to be honest with you," Morgan dished exclusively to ET earlier this week on the set of The Good Wife.
"The first episode you see me in airs Sunday night and we will see what happens, man," the 49-year-old actor teased with an all-knowing smirk. "It is going to a whole new deal."
Morgan added that this vicious big bad is a "total 180" from his current role as Julianna Margulies' newest love interest, Jason Crouse, on The Good Wife.
"When you do what I do for a living, you want to do as many different things as possible and I love the challenge of this character," Morgan explained. "I think it is going to be a great challenge for me as an actor."
So, what exactly can we expect from Negan's horrifying debut? TWD
executive producer Gale Anne Hurd has already warned ET
that one of our beloved characters will
be on the receiving end of Negan's iconic weapon.
"Someone is going to be facing Lucille," Hurd confirmed. "If you don't know what Lucille is, it's what he names his bat. So yes, at some point, someone is going to be facing Lucille."
When we pressed Morgan for details on this particular death, he was (understandably) mum on the subject. "I can't talk much about it as I am under strict orders [from AMC]," he confessed. "And until I see the final cut, I don't know exactly what we will see."
TWD star Lauren Cohan has already promised ET that Sunday's finale will be "the cliff-hangerist episode" of all time, which leads us to believe that we're definitely going to be seeing more of Negan in season seven.
"I am excited and I am ready," Morgan said of Negan's future. "I really I can't wait to kind of step into those shoes, and hold that bat, and do my thing. I am looking forward to it."
As for this Sunday's 90-minute spectacular, Morgan confessed that he is already bracing for a thunderstorm of fan backlash.
"I am fully prepped for hate mail and everything else," he said. "So bring it."
The Walking Dead's season six finale airs Sunday, April 3 at 9 p.m. ET/PT on AMC.
