The White Witch from 'The Chronicles of Narnia' is extremely cold. She has frozen Narnia in eternal winter. Her heart is cold and cruel. She rules with an iron fist and shows no mercy. She's cold not just in her actions but also in her lack of any real compassion or warmth towards the other characters in the story.
One of the coldest names in fiction could be 'Frost' as it directly evokes the idea of cold. Another might be 'Iceman' which is associated with ice powers and a cold, icy nature.
Well, in some fictional works, 'Coldheart' is a really cold nickname. Just the name itself makes you think of someone who is lacking in warmth and compassion. Also, 'Winter's Wrath' can be considered. It combines the coldness of winter with the idea of wrath, indicating a character who is as cold and unforgiving as a winter storm.
Not exactly. While it has elements that draw from real-life situations, it's not a pure, unaltered account of actual events. The filmmakers have added drama and twists to make it more cinematic.
