Fury of Firestorm #4 (1982)

Killer Frost has taken control over all of New York City. She has transformed the five Burroughs into a wasteland of ice, and now declares herself queen of the city. Millions of New Yorkers are frozen in place. Firestorm bows before her, powerless to stop her and desperate to save the people around him. He tells Killer Frost that he will do whatever she wants to save the people of New York. Killer Frost commands him to bring her the true love of her life – an action movie star named Curt Holland. Firestorm flies off towards California to do her bidding. En route, he comes upon his teammates in the Justice League of America. The JLA want to help Firestorm, but he fears that if Killer Frost learns of their interference, she will begin slaughtering people. He briefly argues with them, but they manage to calm him down and bring him back to the Justice League satellite. Red Tornado takes Ronnie Raymond out to Hollywood, California in an effort to enlist the aid of Curt Holland. Curt has no interest in helping someone from the East Coast and turns them down. The heroes then decide to embark upon a secret plan. Red Tornado disguises himself as Curt Holland and secrets a modular thermafrost unit inside of his robotic chest cavity. Ronnie and Professor Stein transform into Firestorm and bring the Curt/Tornado to Killer Frost. Frost attempts to use her ice powers upon Holland to no affect. She quickly learns that Holland's presence is merely a ruse. Red Tornado activates the thermafrost machine and absorbs all of the heat from Killer Frost's body. After incapacitating Frost, the heroes then reverse the polarity on the thermafrost device and use it to thaw out New York City.
