In "Terrors", after being captured, Captain Cold was sent to Belle Reve Penitentiary. He assisted in Icicle Sr.'s breakout attempt, but was taken out of when his inhibitor collar was reactivated.
In "Coldhearted", after five mysterious ice fortresses covered the United States with a blanket of snow, Batman and Flash suspected Captain Cold and the other ice-villains were involved. Hugo Strange told them they had been, and still were, in their cells. However, Captain Cold was in fact responsible for powering one of the fortresses.
- Cold Gun: Captain Cold's primary weapon is his cold gun which allows him to shoot icy beams that create an ice mass large enough to encase entire cars.
