Clarke's blazing red hair is not the only change that fans can expect when "The 100" season 3 airs. Showrunner Jason Rothenberg recently revealed via Twitter that the opening sequence of the show is also "getting a makeover."

"Can't spoil the wheres and whats yet, but it's cool," Rothenberg said.

It looks like the upcoming season is shaping up to be the biggest for the hit post-apocalyptic show.

Just recently, the action-packed trailer for "The 100" was released. It gave a glimpse of a ton of exciting new stuff, including a new war brewing, a new and meaner baddie, Lexa's not-so-welcome return and a Clarke in grave danger.

When season 2 of the show ended, Clarke ran away from Camp Jaha, unable to withstand the thought of having murdered every single Mountain Man in Mount Weather. She finds herself walking among the Grounders and changes her appearance to fit in.

Meanwhile, "The 100" season 3 also packs some exciting things for Raven.

In an interview with Buddy TV, the character's essayer Lindsey Morgan revealed what her character will be up to in the new season.

"I feel in Season 3, we're going to have a chance to see what losing Finn really meant to Raven, what killing all those Grounders in season one felt like to Raven, what losing Clarke now feels to Raven," the actress said. "And who she is now -- losing her leg, being with Wick."

"There [are] so many changes in her world. I wouldn't say a new Raven, but a changed Raven as any human naturally would be after going through what she went through," she went on to say.

That being said, "The 100" season 3 will indeed be a season of many transformations.

"The 100" season 3 premieres Jan. 21 with "Wanheda – Part One."
