The Girl of Steel is set to embark on a new chapter of adventures this fall. And judging by news recently unveiled at Supergirl's San Diego Comic-Con panel, Kara Danvers (Melissa Benoist) will be bringing a few new friends along with her. We just learned that four new cast members will be joining The CW's hit series when it returns in the fall. Click through our gallery to find out who, and what DC Comics roles they will be playing.

Morgan Edge Adrian Pasdar (Agents of S.H.I.E.L.D., Heroes) will be joining as long-running Superman enemy Morgan Edge. Described as a "charismatic capitalist", Edge is a "ruthless real estate developer who will stop at nothing to get what he wants (and what he feels he deserves)." His plans are set to create quite a few enemies, particularly Kara, as well as Lena Luthor (Katie McGrath). prevnext

M'yrnn J'onzz Also joining the cast is Carl Lumbly (Alias, Zoo), who will be playing M'yrnn J'onzz, the father of J'onn J'onnz/Martian Manhunter (David Harewood). M'yrnn is described as "A pacifist religious leader on Mars" who "pushes his son in unexpected ways." This won't be the first time that Lumbly portrays a member of the J'onnz family, as he voiced J'onn J'onnz on both Justice League and Justice League Unlimited. prevnext

Psi The CW favorite Yael Grobglas (Jane the Virgin, Reign, Crazy Ex-Girlfriend), will also be appearing in Supergirl's third season as Psi, a psychic villain who "uses people's own minds against them." The antagonist was first introduced in the pages of DC Comics in 1982's Daring New Adventures of Supergirl #1, and later went on to join the Suicide Squad and the Black Lantern Corps. On Supergirl, Psi is set to have a similar run-in with Kara, which "will affect the Girl of Steel in surprising ways." prevnext
