Fans already know that "The Walking Dead" Season 7 won't be kind to its characters. In the teaser images revealed, some of the characters are under Negan's mercy, raising the chances of one or some of them getting killed off in the series. But before anything else, actor Andrew Lincoln revealed that things will be different for his character, Rick Grimes, in the new season.

Speaking at San Diego Comic Con, Lincoln shared that Rick will feel all broken down at the beginning of "The Walking Dead" Season 7. This is the exact opposite of what viewers saw from Rick in the later part of the sixth season, where his overconfidence landed him and the rest of the group in a very tight position.

"Everything he's fought and bled for and had family members die for, everything that he's worked for two years to get to, has been shattered in 24 hours," Lincoln teased, Comicbook.com reported. "He's not a in a good space. If he makes it through the first episode, he's different. He will be a different man."

But it's not just Rick who will be having a hard time in "The Walking Dead" Season 7. Norman Reedus, who plays fan favorite Daryl Dixon, said that Negan's (Jeffrey Dean Morgan) reign of terror will change the course of things, and it won't be advantageous to Rick and Daryl's group.

When asked what fans can expect from "The Walking Dead" Season 7 premiere, which picks up from the season 6 cliffhanger, Reedus said it's a "brand new world."

"It was hard, and they had to go through things all the time, but they were on a path, and now that path has been ripped from their feet, and things that they believe in are completely different now," Reedus told Entertainment Weekly in an interview. "The world is completely turned upside down."

Based on the particular scene in the comics where Negan whacks a member of the group using his bat, Reedus said the death that results from it will affect the characters differently, but they are all mutually "broken apart at this point." Negan's Law will even come between alliances and break loyalties among the characters.

It looks like it's going to be one dark season premiere when "The Walking Dead" Season 7 returns to AMC on Oct. 23.
