Fox has released another trailer for the upcoming season of the hit drama series “Gotham.” In the latest Season 2 preview, the spotlight is on Oswald Cobblepot a.k.a the Penguin (Robin Lord Taylor).

“Perhaps it’s not our friends, but our enemies that define us,” says the Penguin, in a clip from Season 1. He raises a toast while speaking to his new henchman, Butch. Ironically, Butch once pledged allegiance to Penguin’s archnemesis Fish Mooney (Jada Pinkett-Smit).

In fact, both of them started the series as bottom-feeders in in Mooney’s organization. The trailer focuses on how Season 1 culminated in the Penguin making the ultimate move against Mooney. He pushed her off a rooftop, straight down to her death in the raging dark waters of Gotham’s harbor.

The killing was truly a big moment for Penguin, who had been harboring a lot of hatred for his former boss. She treated him like dirt, so he double-crossed her on numerous occasions. The two of them kept firing shots at one another throughout the season while they were both also fighting for survival. They both spent a good part of the first season manipulating their way around other big-time crime figures like Sal Maroni and Carine Falcone.

Both the Penguin and Mooney also needed to go about their nefarious business while keeping unlikely, but mutually beneficial relationships with law enforcement. Mooney had a close friendship with Detective Harvey Bullock (Donal Logue), while the Penguin formed a bond with Bullock’s partner, Jim Gordon (Ben McKenzie).

Towards the end of the season, Mafia boss Maroni gets killed and Falcone decides to retire. When the Penguin kills Mooney, he declares: “I’m the king of Gotham!”

In the trailer, Taylor tells the audience that despite his character’s triumph against his enemies, sitting at the top of the Gotham underworld is not necessarily a good place. “We all know in Gotham City that’s the most tenuous place you can be,” he says.

In season 2, Oswald Cobblepot develops the character even more and it remains to be seen what kind of Penguin will be seen in the series, compared to previous “Batman” adaptations. "Gotham" is scheduled to return on Monday, Sept. 21, at 8 pm EDT on Fox.
