Appearance
Helisia has long dark blue hair like Musa's that goes past her knees. Her outfit is a floor-length robe that has the appearance of a kimono, it has a pink border and pink flowers on a light tan fabric. Before she was cured, her appearance was rather sickly but she is now more vibrant and smiling more.

Personality
Helisia was very sick thus causing her to be very weak, however she is eager to go out and see the world once she is better. Helisia seems to be rather friendly too, as she wanted to meet Nabu's friends when they had arrived but had to soon retire.

Comics
Helisia is first seen watching Aisha and her friends walk through the research labs until Nabu and Torganis catch her. Helisia is made to return to her room as she is very frail but before they leave, she asks Nabu if she will be able to see his friends again. She is later revealed to be Torganis' daughter and that she is ill. It is also revealed that Nabu's love for her is what gives her the strength to keep living through her illness, which begins to cause a rift between Aisha and Nabu. While out at sea, Nabu confesses that he has fallen for Helisia but he promises to leave her to stay with Aisha once she recovers.

As Winx and Specialists continue trying to help Torganis in his research, Helisia's condition is worsening. as Nabu and Torganis tend to her, one of Torganis' assistants reveals that Nabu and Helisia have even planned to get married, which causes Aisha to lose more faith in her relationship with him. Helisia notices that the Winx are outside and requests to see them, where she quickly takes a liking to Aisha. When she realizes that she must be left alone to rest, she gets a goodbye kiss from Nabu and she wishes him and his friends good luck.

When the group returns in the morning, one of Torganis' assistants bursts into his office to notify him of Helisia's condition which has now become critical. As Torganis and his assistant desperately tend to Helisia, Nabu reveals that they need a transfusion or else she will not make it. Aisha offers to be Helisia's doner and after the transfusion, Helisia's condition starts to improve at a rapid pace.

Some time after her condition has stabilized, Helisia and Nabu go for a walk outside the research labs, where Nabu tells Helisia that his heart belongs to Aisha. Helisia kisses Nabu on the cheek one last time and accepts his choice.

At a farewell dinner held in Nabu's honor, Helisia meets Herdan, one of the Andros University students that will be replacing Nabu. The two of them quickly hit it off once Helisia offers the empty seat next to her to Herdan.
