She also repeatedly flirts with Darkwing, making it clear she finds him rather attractive. In his words: "Why do the weird ones always fall for me?"
Isis 'Icy' Vanderchill was a normal duck who owned the Vanderchill Ice Factory in St Carnard. However, she was rather vain and used a scientific experiment to preserve her beauty. However, it froze her blood instead, making her unable to feel warm and allowing her to give off an aura of cold, in the shape of snow and ice.
She spends most of her time underground, bathing in hot lava, but, one day, she decided to find a better way to keep herself warm, and by breeding a species of firebugs, she melted all the gold in the banks of St. Canard in order to create a reflecto paint that can be used on the whole city itself, allowing her to keep warm all year long.
One day, Darkwing Duck and Launchpad McQuack stumbled upon this mystery and decided to investigate, and, after an encounter with Icy's firebugs, meet Icy herself in her underground lair. Finding herself attracted to Darkwing's good looks, much to his chagrin, she decided to take him out on a date, which did not go so well for our hero! However, when Launchpad stumbled upon her collection of melted gold, which made her imprison them both in blocks of ice! Then she went on to apply her coat upon the city! But Darkwing and Launchpad managed to escape, and using one of Icy's snow blowers against her, defeated her, canceling the effects of her reflecto paint and freezing her into a snowduck. After Darkwing turns her into a frozen snowduck, she's hauled off to jail, and never heard from again.
Isis Vanderchill's only appearance was in the episode All's Fahrenheit in Love and War.
- Eat ice, baby!
