Michael Chiklis Paleyfest

Michael Chiklis is returning to his cop roots in “Gotham” Season 2.

TVLine reports the “Shield” alum is joining the FOX series as Captain Nathaniel Barnes. He sounds like the sort of ally Jim Gordon (Ben McKenzie) needs when the series returns, considering the detective is newly bumped down to the rank of traffic cop.

“Gotham” producers describe Nathaniel as a “tornado” who lands on the Gotham City Police Department, “ripping out the dead wood of Gotham’s police force.”

“He is a law and order zealot; unafraid of making enemies — on either side of the law,” they explain to TVLine. “For Gordon, Barnes is a hero and a mentor, someone with whom he can share the burden of heroism. Captain Barnes proves himself to be a strong ally to Gordon … but one day he will make an equally powerful enemy.”

He’ll be one in a list of many enemies for Gordon, especially since the “Gotham” hero has finally gotten on the Penguin’s bad side.

“I think [Penguin] was deeply hurt by the betrayal Gordon showed him in the finale,” Robin Lord Taylor tells Zap2it of his character. “He was going to leave him there to die in a hospital handcuffed to a radiator.”

There’s also the threat of the Joker looming at the beginning of Season 2. “He’s locked up in Arkham right now,” executive producer Danny Cannon teases. “We get to meet him again and see what he’s blossomed into. Over the first episodes, we’ll see how his ideology spreads.”

“Gotham” Season 2 premieres Monday, Sept. 21, on FOX.
