Polaris takes over after Madelyne is defeated.  Unlike Madelyne, polaris is not interested in playing with humans, but when she encounters the Mystic Warriors while trying to find the energy source, she becomes obsessed with the idea to fight the Mystic Warriors with their fullest potential.  In the beginning, Polaris can beat the Mystic Warriors rather easily, but she can see the Mystic Warriors can become really powerful and develop into worthy opponents and she longs for a challenge.  She creates ice monsters from time to time to train and prepare for the final showdown between the Mystic Warriors and herself.  Her powers concentrate on wind, more focused on ice.  She can freeze anyone by concentrating her powers and shooting it to the target.  Unlike Madelyne, Polaris likes to get a bit more physical when fighting.  She often saves her real powers when she really needs it.  She only disguises herself as a normal human once, just to see if she can find the Mystic Warrior's identities.  Polaris is the only one of the sisters who has a boyfriend, but she hardly mentions it, not even to her other sisters.  She keeps a ice locket on her suit with his picture inside and is only revealed when the Mystic Warriors tear the locket off.  Although she acts a bit cold she does care to find her sister, Angelica but she loves to fight worthy foes as well.
