Jackie is cold-hearted with a high level of selfishness. She is rather snotty and has no trouble with being rude. She has a talent for creating schemes, although this ability is often used in order to get her way. She is very bitter about her life as a servant in the Snow Queen's castle, and has a power-hungry wish to could be the ruler of the kingdom. She was so keen on this idea that she and her brother conspired against the Royal Family and hypnotized the king into freezing the kingdom in ice and was temporarily the queen, although her plans failed in the end. Jackie is a very short and overall small person in comparison to the students of Ever After High. She has snow white hair styled in long spikes that stick out in all directions, Her eyes are a violet color and her makeup around them is in deep purple and aqua colors. Her cheeks are flushed purple with frosty snowflake marks resembling freckles. Her lips are a very dark blue. She has pointed ears and a pert nose.
