"Arrow" Season 4 spoilers reveal that the upcoming installment will have a new era of heroes. Fans could also expect that the superheroes of the TV series will be fighting new villains this coming 4th season.

Comic Book reports that the official twitter account of the show teases fans with the new photo of Thea Queen in her Speedy regalia. Other DC TV series might be concentrating on the "Rise of The Villains," the next season of the "Arrow" will focus on the "new era of heroes that are coming to Star City." But of course, this TV series has its fair share of new villains that will arise in the episodes.

There will also be some changes that will be happenning in "Arrow" Season 4. One of these is the change of name of the city, from Starling to Star City. Of course, this is based on the story that it would honor "the presumed-dead Ray Palmer, who was campaigning for the change." Another change that fans need to look forward to is the slight change of appearance of Oliver Queen's alter-ego, this has something to do of being called "Green Arrow." Aside from his subtle new looks, he will be taking charge of the different heroes that will be working with him- "his sister-sidekick Speedy, Laurel Lance as Black Canary, and even Diggle in an as-yet-un-codenamed helmet/outfit."

As for the villains, Christian Post says that season 4 of the "Arrow" will keep some of the old villains but definitely will bring in new bad guys. But this upcoming will have Damien Darhk as the newest big bad guy. This former former arch nemesis of Ra's Al Ghul will surely bring more chaos in Starling City. According to the report, Damien is likened to Lex Luthor, who is not just ruthless but at the same time cunning. Of course, he is not the only guy who will wreak havoc, Conklin (Ryan Robbins) is the new addition to the roster of criminals. He is also described as sadistic ruthless member of Shadowspire.

"Arrow" is slated to return Wednesday, Oct. 7 at 8 p.m. ET on The CW.
