In Winx ClubEdit
She and Helia have known each other since they were children, making them childhood friends.
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 has lavender hair and green eyes. She wears a light green dress that goes over her left shoulder. On the dress there is an indigo flower on the edge of the dress on the left. She wears gold bracelets on her left arm and a green vine on her upper right arm. She wears her hair in a very low and loose ponytail held together by indigo flowers and she wears another on over her left ear. She wears white socks with teal heels.
Powers and AbilitiesEdit
- 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.
On Sora's TeamEdit
When Helia joined the team, she wanted to stay close with her friends, and her pure heart won many new friends on the team.
