Krystal

Princess Krystal is the Princess of Linphea, Flora's realm. She is first introduced in Return to Alfea, where she is revealed to be an old friend of Helia.

Pre-series
She and Helia have known each other since they were children, making them childhood friends.

She also seems to know Diaspro well, though its unknown if they ever were friends or did Krystal just know about her and Sky's past engagement plans.

Season 5
She is a freshman student at Alfea in this season. She noticed Helia at Alfea's yard. Surprisingly, Helia introduced Flora as a "friend" of him to her. Krystal drags Helia away, telling him that they needed to catch up. This concerns Flora. Later on, Helia gets hurt by an attack of the Trix, but Krystal heals him with her magic. Despite being a possible rival for her, Flora shows kindness and respect to her as she does all other fairies. Also, she agreed to heal Sky's memory when asked by Flora, but failed as there was a barrier "something Sky doesn't want to remember" which is presumably the bad luck bestowed by the necklace he lost. In another attempt to bring back Sky's memories, she brings Diaspro in hopes that will bring Sky's memories back. This upsets Bloom and Stella.

She is later seen during the school dance. And at the annual Wind Riders competion, she was seen with Roxy and Mirta. Then she is seen at Domino's palace with her mother, discuss about the way of defeating Tritannus.

She is later seen playing volleyball at Alfea along with Stella, Musa, Aisha, Tecna and Flora. She was on the opposite team and she easily won by listening to Palladium's advice then after she won she ran and hugged Helia after the game, Flora saw this and look very upset and left. Helia congratulated Krystal but told her he needed to speak to Flora, but when he saw that she was gone, Krystal then realized that she was interfering with their relationship.

She later appeared in the Alfea breakfast hall looking rather sad, she goes over to Flora and ask her if they could have a private talk about Helia. Krystal tells Flora she is sorry for the trouble she did to their relationship. Krystal then remember's the hug she had with Helia but realises that Flora was watching it when it happened. Krystal tells Flora that she and Helia are just friends and that Helia loves her but instead of feeling relived Flora gets up to leave but before she does Flora tells Krystal "I wish I could believe that" clearly still not convinced.

Krystal's final appearance was in the final episode where she along with some other Fairies were on Andros watching the Winx perform.

Powers and abilities
Krystal has healing power and uses it to heal Helia after he was attacked by Darcy.


 * Healix Awake: Used to heal Helia after he was attacked by Darcy. However, it was unable to restore Sky's memories, because the Pendant of Eraklyon blocked the healing power.

Since she is from planet Linphea, Krystal has special effect - the colorful flowers - come out when she uses her powers, like Flora, although they are not as colorful as Flora's and Flora seems to have more of this, may be because of Flora's strength, experience and transformation level.

Trivia

 * Her name is a variant spelling of "Crystal", means "ice".
 * Cymphonique Miller, Krystal's Nickelodeon version voice actress is also the singer of the opening of the Nickelodeon Winx Club Specials.
