Icy, like her name, is very cold and is often cruel for the sake of being cruel, ridiculing people she does not approve of. As she was taught by Headmistress Griffin, she and her sisters, Darcina "Darcy" and Stormella "Stormy", hate the Alfea fairies to a fault, and especially the Winx Club, specifically Bloom. Bloom because she evades them time after time. Before the Pixies were introduced in Season 2, she often called the fairies "pixies", as there was no other character called such at this time. After Season 2, she called them "twerps," "geeks," and "losers." She is often the most cunning of her sisters, and is Baltor's favorite more often than Darcy or Stormy. An old nickname, mentioned in Season 3 by Darcy while hanging out in Baltor's lair eating ice cream, was "Six-Scoop Icy", because she ate so much ice cream when she was younger. It is unknown if Icy, Darcy and Stormy are actually sisters; "sister" is a term often used about good friends, or more likely, in a coven.
