Guess Which "Wolf" Was Promoted On Arrow?

The CW recently announced that Colton Haynes, former star of MTV's Teen Wolf, will be sticking around for good as Roy Harper on Arrow.

While Haynes has been officially promoted to a series regular, he will finish out this season as a guest star, and will take on a larger role when the show returns in the fall.

In the comic books, Ray Harper eventually becomes the superhero's sidekick Red Arrow. Now those are some big shoes to fill!
