DuringArrow’s Hall H panel at Comic-Con this past summer,Stephen Amellshowed off Oliver Queen’s new costume to the crowd, while fans were also shown early concept art of the costume worn byDiggle(David Ramsey) inSeason 4. As fans impatiently await the season premiere,“Green Arrow”, debuting Wednesday, October 8 at 8 PM ET on The CW,Entertainment Weeklyhas our first look atDavid Ramsey’s full costume, which, to a certain extent, resembles the Marvel character Magneto’s costume. However, executive producerMarc Guggenheimreveals that Diggle himself doesn’t view this outfit as a “costume.”

“We try to be very consistent with our characterization. I don’t think Diggle looks at it as a costume per se. Oliver, in the last season, gave him advice in terms of concealing his identity, and so Diggle approaches it from a very practical standpoint. He followedOliver’s advice and he’s got a means of concealing his identity, but I think Diggle would probably react to anyone calling it a costume.”

TheSeason 3finale,“My Name Is Oliver Queen”, ended with Oliver (Stephen Amell) and Felicity (Emily Bett Rickards) leaving Star City to start fresh, but it isn’t known exactly where they went to, or when they will eventually return to their home city. It isn’t known yet if Diggle will get a superhero alter-ego, but some have speculated that he could become theDC Comicscharacter known as The Guardian. In the comics, The Guardian was a former cop who became a costumed vigilante, who had connections to a number of characters who are already established in the series, such as Arsenal (Colton Haynes), Atom (Brandon Routh) and Wildcat (J.R. Ramirez).
