Carbon Costume 
Arsenal from Arrow
Roy Harper is better known in Arrow by his alias of Arsenal. He is played by Colton Haynes on and appears as a recurring character until he joins forces with Oliver Queen and enters the vigilante community. His path is still far from easy but he he one of Oliver’s most loyal allies and ultimately ends up engaged to Thea Queen, Oliver’s sister.
Although Roy has taken up the green mantle of Arrow and has put off his own red Arsenal suit several times, he is the one and only Arsenal. Identified by the red and black coloring of his clothes, the many knives strapped to his legs, and his iconic laced leather jacket, he is often seen as a harsher version of Oliver Queen’s Arrow.
Black Canary from Arrow
Laurel Lance, AKA Black Canary, is a super-heroine from the DC Universe. She appears in the CW show Arrow played by Katie Cassidy. The former assistant DA of Starling City, Lance turned to crimefighting when her sister Sara Lance, also known as Canary, was murdered. The Black Canary also appears in the television shows The Flash and Legends of Tomorrow.
Adrian Chase

Towards the end of season 5, Adrian equips himself with tactical gear as shown in this guide.
Green Arrow
In Arrow, Oliver Queen (Stephen Amell) is Green Arrow, a billionaire playboy who dons a costume and fights crime. Sounds a lot like another guy we know. No surprise that his weapon of choice is the bow and arrow.
John Constantine
Based on Alan Moore’s Hellblazer comics, John Constantine (Matt Ryan) can see the supernatural in our everyday world. He must do all he can, including the morally questionable, in the fight against the evil paranormal. You can simply substitute a black tie to dress up as Keanu Reeves’s Constantine. Whoa.
