Firestorm Villain: Killer Frost
Or: Gerry Conway and his Gender War issues!
The early Gerry Conway had some pretty good stuff. Since she's coming back as a Black Lantern, here's a look at the original Killer Frost. (Roughly 16 pages, poor dial-upper..)

Killer Frost has taken over New York (where only Firestorm and Red Tornado hung out) by breaking water mains everywhere and then freezing it all. She demands Firestorm bow to her or she'll start killing hostages.
Curt Noland is the DC counterpart to Burt Reynolds, of course.
After being defeated, she is frozen in jail to prevent her from using her powers. Outside, a guard is watching birds fly around wires. Inside, the warden is visiting. (7 scans from Firestorm 20, Gerry Conway writes, art by Rodin Rodriguez and Rafael Kayanan)
And who is that one man you ask? Why it's Martin Stein, the passive half of the composite hero Firestorm. Here is Frost while stalking him.
The offhand, bloodless humor is somehow more evil than all the cackling of modern villainy.
Because Stein is a superhero, he escapes, making her think he's dead.

One of the guards manages to escape, while his comrades beg for help. Frost watches impassively. The remaining guards drop their weapons, saying that that counted for something, right?
She simply walks up the freeway, freezing as she goes 'with the air of a pedestrian at a crosswalk'. As she decays, she looks older. Assorted pages from their fight:
