A brand new Gotham Season 4, “Gotham Learns What It Means To Fear,” showcases Scarecrow as he shows Gotham what it means to fear!

However, Scarecrow isn’t the only thing the citizens of Gotham will fear. There also appears to be a new Joker on the scene who slams Jim Gordon up against a wall while laughing maniacally.

The promo also gives us a look at Penguin’s Iceberg Lounge with a frozen Riddler as its prize centerpiece. While Penguin may be living large at the beginning of the promo, his attitude quickly shifts when Scarecrow descends on the city. In fact, he even calls out the GCPD for being completely ineffective as you see the fear in his face.

Along with showcasing Scarecrow, we get a bunch of scenes of Bruce taking the fight to the villains of Gotham in his new proto-Batsuit. And there is a short clip of what appears to Ra’s Al Ghul.

Gotham Season 4 will showcase an expanded Batman rogue’s gallery including Solomon Grundy, Sofia Falcone, and Professor Pyg along with mainstays Penguin, Riddler, and Poison Ivy.

Gotham will debut on Thursday, September 21 on Fox. The show stars David Mazouz as Bruce Wayne, Ben McKenzie as Jim Gordon, Donal Logue as Harvey Bullock, Robin Lord Taylor as Penguin, Cameron Bicondova as Selina Kyle, Erin Richards as Barbara Kean, and Sean Pertwee as Alfred Pennyworth.

Here’s the official promo from Fox:

Gordon fears Jonathan Crane (guest star Charlie Tahan) is still alive and back in Gotham, when The Scarecrow’s signature MO is used in a series of robberies. Meanwhile, Penguin’s “licensing” of crime in the city backfires during the grand opening of his new Iceberg Lounge. Also, in the aftermath of his encounter with Ra’s Al Ghul, Bruce begins his vigilante watch in the all-new “Pax Penguina” season premiere episode of GOTHAM airing Thursday, Sept. 21 (8:00-9:00 PM ET/PT) on FOX.
