Michonne is in the house and that means no "Walking Dead" zombie is safe.

The new teaser clip premiered during "The Walking Dead" marathon and special "Talking Dead" episode from the Sun., July 8 marathon on AMC.

Michonne, a fan-favorite comic book character, made her appearance in the Season 2 finale. "Treme" actress Danai Gurira will join the fight against the walkers as Michonne when "The Walking Dead" returns for a third season in October 2012.

"The essence of the character -- her personality, her motives, everything that makes Michonne Michonne -- remains intact from the comics," comic scribe and "Walking Dead" executive producer Robert Kirkman told EW. “But like a lot of things on the show, there will be little tweaks and differences here and there. We saw that her introduction is slightly different from how it was in the comic, and her interaction with Andrea is really going to be a really cool addition to the character that I think will get television viewers up to speed, and they'll get to know her a lot faster than comic book readers did."
