The final panel Saturday at Comic-Con International: San Diego is Warner Bros & DC's three-hour A Night of DC Entertainment in Hall H. In this panel, it's all things television for Warner Bros. and DC, from superhero shows such as Arrow, The Flash, Gotham and the upcoming DC's Legends of Tomorrow, Supergirl and Vixen, along with other shows such as Vampire Diaries.
The panel begins with Vampire Diaries' Ian Somerhalder taking the stage to introduce a highlight reel for the last season of Arrow
Afterwards, Arrow himself -- Stephen Amell - came on stage in his just-unveiled season 4 costume.
"San Diego Comic-Con, you have not failed this city," Amell said, speaking as Arrow. "I have lost people forever. But Star City still needs heroes. All of you have come so far, and I ask you to come a litle bit further... with the Green Arrow."
Then Amell was joined by castmates Katie Cassidy, Emily Bett Rickards, David Ramsey, John Barrowman and Willa Holland. Joining them were DC CCO Geoff Johns, and Arrow executive producers Marc Guggenheim, Greg Berlandi, Wendy Mericle and Andrew Kriesberg.
"We've always said the progression for Oliver is from Arrow to Green Arrow, and this is the next step," said Berlanti.
Berlanti went on to say that the new season is about who Oliver is going to become rather than who he was.
Kreisberg chimes in to say that Queen is in a "much better place" in the upcoming season premiere.
"He's happy, he's in love," Kreisberg revealed. "I think that feeling infuses all the character."
He adds that while there will be more humor in the new season, there will still be "shooting arrows" and rain scenes.
Geoff Johns then hit upon the recent casting of Neal McDonough as Damien Darhk for the fourth season, but said there's "another" villain coming after Darhk.
"There's a lot of characters coming up that people won't really guess, that will appear soon."
Co-showrunner Marc Guggenheim cuts straight to it, saying that both Anarky and Mister Terrific would debut in Arrow's fourth season.
"[Mister Terrific's] got to work with Felicity. Our version of Mister Terrific also happens to be gay," Berlanti revealed.
Willa Holland revealed that she'll be wearing a red leather costume as Speedy in the new season.
"I had tears of joy when I tried on the outfit for the first time," Holland said.
Barrowman chimed him that he didn't know if he'll be retaining his hood in the new season or taking on the wardrobe of Ra's al Ghul, leading Guggenheim to say that he'll be donning the hood in the third episode.
The talk of costuming and looks continued, with David Ramsey being asked if the facial hair he has on stage is one he'll have in the new season.
"I don't know if it'll go with my new helmet," Ramsey said, adding that he has a real superhero costume in the new season -- joking that it's called "Black Driver."
Turning to Fan Q&A, Amell is asked if his character will be less dour and more "silly" as he is in the comic books.
"I did just ask everyone to follow the Green Arrow," Amell said, referring to his in-character monologue at the beginning of the panel," so I think we're going to move into a more Green Arrow-y direction."
Next up was a question about changes to the characters' dynamics with each other in the new season. Amell said that more is out in the open between characters, specifically referring to their secret identities. The Arrow frontman said that that opens up connections between Laurel and Thea, as well as Malcolm and Felicity.
One fan asked an interesting question: has any of the actors had to be like their character in real life?
"I once got mad at a guy at a hockey game and he started talking back to me," Amell said. "And some guy yelled out, 'Hey! That's the Green Arrow!"
The proverbial baton was then passed the upcoming animated show Vixen, with a clip:
Then immediately onto a highlight reel from The Flash.
Note the Flash glowing blue as he runs. And then, of course, the voice-over ("My name is Jay Garrick, and your world is in trouble") and the final text: "Zoom is coming."
With that, The Flash cast was brought on stage: Grant Gustin, Candice Patton, John Wesley Shipp, Carlos Valdes and Danielle Panabaker, with Andrew Kreisberg, Greg Berlanti and Geoff Johns hanging around from the Arrow portion.
Talk went directly to that mention of Zoom in the trailer, with Kreisberg saying he'll be the "Big Bad" of the new season.
"He's going to be faster than the Reverse-Flash, faster than the Flash, and it's going to be very hard to catch him."
Teddy Sears is confirmed as playing Jay Garrick in the new season, with Shantel VanSanten joining as Patty Spivot. Wally West was also mentioned as appearing in the new season.
Sears is best known for his role in HBO's Masters of Sex, while VanSanten appeared in The Messengers and One Tree Hill.
"Jay Garrick is integral to the Flash mythology," Kreisberg said," and he's never really been portrayed in live action. Now that we've established our Flash, we thought it was interesting to bring in the original Flash and create a brand-new episode for Barry to have."
The second season of The Flash will follow up on the events of the finale, and add into that the Earth-2 characters being a new wave of metahumans.
"This year we're going to be introducing characters from Earth-2," Berlanti reveals. "That's obviously the origin of Jay."
Valdes talks about what his character, Cisco, learned in the finale and how that is touched on in the new season.
"As fans saw in the latter half of Season One, Cisco starts having these dreams and starts underoging these biological changes that take place in his mind. Those kind of augment themselves over time, and yeah, the beginning of Season Two deals with how Cisco deals with that change."
Panabaker added that she's "beyond excited" about her character doing more as Killer Frost "one day."
When asked about more additions to the television Flash's rogues gallery, Kreisberg said there'll be several "returning favorites" such as Grod, Captain Cold, Golden Glider and some new villains in addition to Zoom.
"[Zoom] is going to be terrifying and scary and fast, and it's going to be all kinds of cool," said Kreisberg.
After a question about Cisco becoming Vibe was deflected by the actors, the The Flash presentation ended.
Next up, DC's Legends of Tomorrow. A video package was shown, mostly from the original trailer but with a few new cutscnes and some concept art for the teammembers.
Johns took over the moderator duties for this portion of the event, ushering in cast members Ciara Renee, Brandon Routh, Dominic Purcell, Caity Lotz, Victor Garber and Phil Klemmer, along with Berlanti, Kreisberg and Guggenheim joining them on stage.
Guggenheim reveals that the new seasons of The Flash and Arrow would set up DC's Legends of Tomorrow with their early episodes, with the annual crossover between those two shows cementing the foundation for the mid-season series.
Routh says that he thinks his character of Ray Palmer (a.k.a. the Atom) will have a desire to lead this team atsome point.
Caity Lotz said that the White Canary isn't just a visual change for the character, as her time in the Lazarus Pit changed her.
"I want her to go just nuts, off the wall," Lotz said. "That's my plan."
Purcell said his character, Heat Wave, is "pissed" about joining the team, but has not other choice, while Captain Cold will find being told what to do by Professor Stein and Palmer not very bearable.
The previously revealed big bad of the debut season, Vandal Savage is then talked about next.
"Part of the fun of the show is, 'how do you defeat somebody you can't kill?'" said Kreisberg.
The team will fight Savage in various time periods during the series said.
"DC's Legends of Tomorrow, all it is, is the crazy ideas," Kreisberg said. "It's bonkers."
The veteran actor of the show, Victor Garber, said that Comic-Con was overwhelming but thanked the fans. Talking about his character, Professor Stein (who is one half of Firestorm), Garber said "he has a certain arrogance that makes him believe he's actually capable of mediating this dysfunctional family."
Renee said she's read "like a million" comic books preparing or her role as Hawkgirl, and has also being doing physical training such as boxing and krav maga.
Johns mentioned earlier that Hawkman would also appear at some point in DC's Legends of Tomorrow.
Berlanti, who executive producers all of the shows on the panel so far, thanked the fans for the support they've had so far.
Guggenheim added to that, saying: "I think one of the great things about the show is that we get to visit all these different corners of the DC Universe all throughout all time. We'll be allowed to go to all of these incredible places and all these incredible moments."
Next up: Gotham. As with previous shows in this presentation, a highlight reel followed by a look ahead. In the case of this Fox show, the inmates running wild in Arkham Asylum.
After that Johns remained on stage and was joined by Gotham actors Ben McKenzie, Donal Logue, Robin Lord Taylor, Sean Petwee, Camren Bicondova, David Mazousz, Erin Richards and Cory Michael Smith, as well as executive producers Bruno Heller, John Stephens and Danny Cannon.
"This season is bigger, more colorful, more intense, more exciting,"said Heller.
Johns said that Heller's initial pitch for Gotham clued him in on the former Rome showrunner being the right for the part.
"There are more stories told about Batman than any other character, ever," said the DC CCO. "You need someone like Bruno to give it a new spin."
Heller revealed that Gotham season 2 will be about the rise of Gotham's idiosyncratic villains, seguing from simple criminals and mafioso-types into more garnish and iconic as in the comic books.
"There'll be new heroes introduced on the good guys' side," said McKenzie, who plays James Gordon." And they'll have to band together to fight these villains."
Gordon's relationship with Harvey Bullock, played by Donal Logue, was hit upon, with McKenzie saying a "mutual respect" is being formed that will turn into a "partnership for years to come."
Logue chimes in to say that that the arrival of Gordon "reinvigorated" Bullock initially, but that his character is "beaten down" after the earlier season finale.
"At this stage when we find Harvey in season two, he might be beaten down," Logue revealed. "He might be a little less idealistic than Gordon about our chances to stem the tide of the bad coming."
Gordon's relationship with Kim Richards' Barbara is asked about next.
"The relationship between me and Jim has changed quite alot," said Richards. "Because I killed my parents and he's a police officer. So it's strained, to say the least."
Heller adds that Barbara is "the crazy ex-girlfriend from hell, but it's also the story of fulfilling your potential. It's just crazy potential."
Sean Pertwee said that in the new season, the relationship between his character of Alfred and the young Bruce Wayne will be deepened.
Robin Lord Taylor is then asked about his character of Oswald Cobblepot, with the actor saying he's on a new level.
"He's achieved his goal. He's the king of Gotham," Lord Taylor explained. "He spent the whole first season laying the groundwork. He knows that once you reach the top, there's someone right there ready to take you down. He's prepared to fight to stay up there."
Cameron Monaghan appeared in the crowd to interrupt the next fan attempting to ask a question, asking "How high is your pain tolerance?"
Monaghan plays Jerome, whom Fox has heavily hinted would become the Joker.
Security grabbed Monaghan in a bit of theatrics, with McKenzie adding to that by channeling Jim Gordon to say "I'm going to find you Jerome, and I'm going to take you down."
Next up: Supergirl. After the trailer is shown, the stage is reset and a new group comes onboard. Supergirl actors Melisaa Benoist, Chyler Leigh, Jeremy Jordan, David Harwood and Mehcad Brooks, followed by executive producers Greg Berlanti, Ali Adler, Andrew Kreisberg, Sara Scheckter and Geoff Johns.
Adler calls Supergirl "a story that needed to be told."
"You come in and see her as female and you'll go out and remember her as powerful," said the producer. "She's a badass."
Johns said a superhero show led by a woman was overdue, with Berlanti adding that they're doing it right by following the comic books.the
Talk then turned to Warner Bros., CBS and DC finding the right person to play Supergirl.
"We saw thousands of women, and [Melissa Benoist] was the first one we saw," said Kreisberg.
Kreisberg added that coincidentally both Stephen Amell of Arrow and Grant Gustin of Flash were the first people to audition for those title roles.
Benoist chimed in to offer a more pessimistic perspective on the audition, remembering after it was done thinking "'I blew it. That was terrible."
The actress describes her first fitting with the costume as positive, however.
"It's hard to articulate the way that it feels," said Benoist. "It really does transform you internally. It's impossible not to feel empowered and to feel hope and strength and bravery when I'm wearing it. I feel like a different person."
Harwood talks about his character of Hank Henshaw, who in comic books becomes the Cyborg Superman.
"I like to keep poeple guessing, so the grey area I think is where this character exists," Hareood explained. "You don't know whether he's got good intentions or bad ones. You're just going to have to wait and see."
Adler then revealed three new additions to the show: Livewire, Reactron, and Maxwell Lord. Lord will be played by Twilight's Peter Facinelli, who then joined the panel, stating the last time he was in Hall H it was for Twilight.
Kreisberg continues on, pointing out that Supergirl is deeply inspired by Richard Donner's Superman: The Movie in its positive tones.
After that, they segued into a screening of the Supergirl pilot.
