Arrow's sixth season will soon be upon us. But aside from the fallout of the season five finale's explosive ending, not much is known about the upcoming season. With the show's San Diego Comic-Con panel, that has begun to change - with the help of a few significant casting announcement.

During the panel - moderated by's Jim Viscardi - it was revealed that Michael Emerson (Lost, Person of Interest) will be joining the series.

Guggenheim also said to expect an announcement about Richard Dragon, a Green Arrow villain from the comic.

It was also announced at the panel that David Nykl, who portrays Oliver's former Bratva confidant Anatoly Knyazev, will be making a return appearance in the upcoming sixth season. With Anatoly and Oliver parting on rather unfortunate terms in season five, there are quite a few possibilities as to what significance it will have in the upcoming season.

Arrow will return for its sixth season on a new night and time - Thursday, October 12th, at 9/8c, on The CW.

After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea. He returned home to Star City, bent on righting the wrongs done by his family and fighting injustice. As the Green Arrow, he protects his city with the help of former soldier John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), his vigilante-trained sister Thea Queen (Willa Holland), Deputy Mayor Quentin Lance (Paul Blackthorne), brilliant inventor Curtis Holt (Echo Kellum), and his new recruits, street-savvy Rene Ramirez (Rick Gonzalez) and meta-human Dinah Drake (Juliana Harkavy).

Oliver has finally solidified and strengthened his crime-fighting team only to have it threatened when unexpected enemies from his past return to Star City, forcing Oliver to rethink his relationship with each member of his "family".
