Belinda, The Ice Queen

Synopsis
Belinda was the queen of the snow-men in the north pole. At some point, she decided that she was going to be a rival to Santa Claus, by having her snowmen make toys out of ice. When this effort seemed futile, she ordered her snowmen to sabotage Santa with a snowstorm.

It is unclear what powers Belinda may have had, though she did not seemed bothered by extreme cold and may have had power over ice and snow, like her dwarfish snowmen.
