Just a week ahead of the show's premiere, CW has just released a brand new trailer for 'Arrow' season 7. The trailer comes after a "sizzle reel" was released earlier and shared by actor Stephen Amell himself.

The new trailer offers a first look at the mythical Longbow Hunters. At the same time, it also gives rise to a mystery among the viewers as to who the new Green Arrow might be. It also highlights the most important developments that fan can expect in the new season. It shows Oliver Queen (Stephen Amell) spending time in a SuperMax prison after he surrendered to the FBI and revealed himself as the Green Arrow in the season 6 finale. 

The trailer also shows that, outside of Slabside prison, Team Arrow will be in a new state. It starts off with Felicity Smoak's (Emily Bett Rickards) passionate speech about continuing Oliver's legacy. After the speech, Curtis Holt (Echo Kellum) says that he has ended going out as a superhero after Oliver got arrested. The final hint was by Laurel Lance/Black Siren (Katie Cassidy) as she can be seen joining Team Arrow in some forest kind of set up.

The first look at the Longbow Hunters shows a team of villains consisting of Red Dart (Supernatural's Holly Elissa), Kodiac (Van Helsing's Michael Jonsson), and The Silencer (Orphan Black's Miranda Edwards). The trailer also clearly states that this group has ties to Ricardo Diaz (Kirk Acevedo), so one can easily assume that they will now be a threat in a unique way as well. 

So the mysterious Green Arrow figure is not Oliver. No one knows who is exactly behind the suit but some suggest that it might be Roy Harper (Colton Haynes) who might return to the show in a way no one would expect. 

The season seven premiere of' Arrow', titled as 'Inmate 4587', will debut on Monday, October 15th, at 8/7c on The CW.
