AMC's The Walking Dead is adding another character to its ranks.

After adding Michael Cudlitz, Josh McDermitt and Christian Serratos as iconic comic characters Abraham, Eugene and Rosita, respectively, the zombie drama will add another major player to its ranks. Greek alum Andrew J. West has boarded the series based on Robert Kirkman's comics, The Hollywood Reporter has learned.

Character details are being kept under wraps, but West will appear in the second half of The Walking Dead's fourth season and play Gareth, a character who does not appear in the long-running Image/Skybound series on which the AMC show is based. However, sources tell THR that while Gareth might not be playing someone from the comics, he is a remix of sorts of an unidentified character from the series. Gareth will have what sources say is a big presence and play an important character on the drama from showrunner Scott M. Gimple.

West will be credited as a guest star in season four with an option to be promoted to a series regular in the recently announced fifth season. The young actor, whose credits also include Suburgatory, Castle, Body of Proof, The Whole Truth and CSI, becomes the latest addition to the cast. This season, The Walking Dead added Larry Gilliard Jr. (Bob) and promoted Chad Coleman (Tyreese), Sonequa Martin-Green (Sasha) and Emily Kinney (Beth) to series regulars as the show repopulated its ranks following the bloodbath of season three.

Like the debuts for Cudlitz, McDermitt and Serratos' characters, the exact episode in which West will make his first appearance is being kept close to the vest.

For his part, Gimple -- a longtime fan of the comics -- has taken a "remix" approach to Kirkman's source material. "In some ways, the things that divert from the comic this year have actually served being closer to the comic in some ways," the new showrunner told THR ahead of the fourth season premiere. "There's going to be some looping around to the comic and remixing. That's how I essentially look at it: It's a remix of the comic."

West is repped by ICM Partners and John Pierce at The Group. The Walking Dead has two more episodes left in the first half of its fourth season before its winter hiatus. The series will return for its second half in February.
