Fox has released a new trailer for season two of "Gotham," and it promises mayhem and chaos.

Season two will once again center on Detective Gordon as he rises through the ranks to his eventual place as Police Commissioner. But long before he's aligning himself with the Caped Crusader, he's going toe-to-toe with iconic Batman foes such as The Riddler, Two-Face, Catwoman, The Penguin and The Joker. Each classic criminal is trying to make a name for themselves as they begin their reigns of terror over Gotham.

Showrunner Bruno Heller ("The Mentalist," "Rome") promises that season two is the "rise of the villains" and viewers will get their fair share of crazy loons. Ben McKenzie returns as Gordon and he is joined by Donal Logue, Sean Pertwee, Robin Lord Taylor, Erin Richards, David Mazouz, Camren Bicondova, Zabryna Guevara, Cory Michael Smith, Victoria Cartagena, Andrew Stewart Jones and John Doman. Newcomers for the second installment include Natalie Alyn Lind, Jessica Lucas, James Frain and Michael Chiklis.

"Gotham" will debut its second season on Monday, Sept. 21 on Fox.
