With just over three months left until Arrow returns for its Season 3 Premiere, the producers have yet to announce which villain Oliver Queen (Stephen Amell) will square off against this fall. Executive producer Andrew Kreisberg wouldn't reveal the new enemy's identity, naturally, but he did say that this season's nemesis will be much different than the revenge-driven Slade (Manu Bennett) from Season 2.

The season will be set six or seven months after the Season 2 finale, when crime goes down in Starling City and the police aren't chasing after Oliver's vigilante alter-ego. However, this year's villain will present a new set of challenges for Arrow.

"Slade had a very specific agenda-he was out for revenge and had set up this elaborate five-year plot. What's interesting about the villain in Season 3 is that he doesn't necessarily disagree with [Oliver]. He doesn't have any personal animus towards the Arrow, and he actually in some ways has a very similar worldview. [But] the Arrow is thinking too small. In some ways, as Oliver is struggling with whether or not he can be the Arrow and Oliver at the same time, the villain of Season 3 is saying, 'Being Oliver Queen is what's holding you back from fulfilling your true destiny.' So it's a very interesting dynamic, but it is tied in the same way that Oliver last year was wrestling with, 'Am I a hero or a killer?' The theme of identity is tied up very much in how the villain is presented to Oliver."

While one "speculative fan theory" suggests the villain will be Ra's al Ghul, the father of Nyssa (Katrina Law), the executive producer revealed that the casting and the character's identity will be revealed "soon," possibly at Comic-Con 2014.

Andrew Kreisberg will be pulling double-duty on The CW this season, serving as executive producer on both Arrow and the new spin-off series The Flash. Last week, we reported that both Arrow and The Flash will be featured in a crossover episode, set to air sometime in November which will serve as the eighth episode for both shows. Here's what he had to say about the crossover, and how it accelerates both storylines.

"It's really going to be an adventure with the Arrow and The Flash on both episodes. Watching the two teams come together and fight alongside each other, it's one of the most fun parts. We just don't believe in waiting. We really believe in accelerated storytelling and especially for those first nine episodes of the season-for both shows-hopefully we've designed it so that none of these [make you say], 'Well, I missed that one, it's fine.'"

He also teased that the crossover leads into explosive mid-season finales for both shows

"(We have) spectacular and amazing midseason finales planned for both shows that are both game-changers ... and what better way to lead into it than by having this amazing team-up?"

In related news, TV Line is reporting that DC Comics character Sgt. Bette Sans Souci, a.k.a. Plastique will be appearing on The Flash at some point in its first season. Here's how the character is described by the site.

"The series' incarnation of the metahuman is a fetching young redhead who was a bomb specialist with the Army before she was injured by an IED in Iraq. Since being exposed to the Central City explosion, she can turn any object into a bomb with just a touch of her hand - not a bad comrade for The Flash to have on his team, eh?"

Don't be surprised if this character is confirmed at the show's Comic-Con panel later this week. Stay tuned for more news on both Arrow and The Flash as the San Diego convention draws closer and closer.
