According to The Hollywood Reporter, Negan is expected to arrive in the season six finale and then return as a regular for season seven.
Series star Andrew Lincoln told THR, "What struck me, that I've always been excited about, is: We're coming into the sixth season of this show... And it's the medieval part of The Walking Dead comic, where you realize that there are these isolated communities, but don't really know other ones exist.
"But they're all building and forming themselves with their own image. And then there's a clash of those communities. That, to me, is really interesting and when it gets really exciting with all the action.
"It turns into this insane, near-apocalyptic landscape that we've never seen before. That is almost a reimagining and a restart for society and humanity. And that is such a rich thing to tell."
