Gotham Sneak Peek Released at New York Comic Con

On the final day of New York Comic Con, Gotham scared up some new footage for fans attending the star-studded panel.

The five-minute video began by recapping what's been going on in the dangerous streets of Gotham over the last three episodes. Fans watched as the Scarecrow was born, Penguin began his rule over crime in the city and The Riddler being featured as a club centerpiece.

However, almost four minutes into the video, new footage was unveiled and new characters were introduced.

It was revealed at the end of episode three that Ra's al Ghul and Barbara were working together, plotting something terrifying in Gotham. This footage showed the two of them in Barbara's new base of operations, talking about their new ideas. Just when you thought you'd seen everything Gotham had to offer, the camera turned to reveal a horrifying character simply referred to as Dogboy.

Along with another man, Dogboy is sent by Ra's and Barbara to retrieve al Ghul's knife from Bruce, and he's given permission to kill the young boy when he's done.

You can watch the entire video above, and you can check out new episodes of Gotham on Thursday nights at 8 p.m. ET on Fox.
