Diaspro/Series

Pre-Series
At some point in her life, Diaspro was betrothed to Prince Sky, mostly for political reasons. To prepare herself to become the future Queen of Eraklyon, Diaspro practiced and perfected all manners of etiquette and protocol. Diaspro herself was overjoyed to be promised to the man she loved but failed to see that Sky did not feel the same as she did.

Season 1
Diaspro makes her first appearance in "Secrets within Secrets", as she was invited to Red Fountain's Exhibition Day. She is walking behind her betrothed's parents, having a conversation with Brandon through a device when Bloom bumps into her. Diaspro showed her hostility and then forbade Bloom to look at her boyfriend, referring to Brandon. She then walks off, unknowingly setting off tension between them. Bloom now believes that she is one of the Trix in disguise.

After being seated to observe the exhibition, Diaspro was falsely lead out of sight by Bloom under the pretense that Sky wishes to see her. Diaspro has no clue as to what Bloom is accusing her of but because Bloom is so determined to "expose" her, she transforms and attacks Diaspro.

Diaspro transforms and retaliates, revealing herself to be the Fairy of Gemstones. They interrupt the ongoing exhibition; when Diaspro is defeated, she rushes to Brandon calling him "Sky", confusing Bloom. Angry with Bloom's false accusations and assault, Diaspro reveals that Brandon is actually Crown Prince Sky of Eraklyon and her fiancé. But before she could give Bloom a piece her mind, Sky interrupts her and seemed to only care about Bloom, which upset Diaspro greatly.

In "The Fall of Magix" she had tried to convince Sky to return to Eraklyon and allow the other Specialists to fight on their own. Sky answered by cutting the ladder leading up to the ship, causing Diaspro to leave in anger, ending their relationship.

Season 2
In this season, ninja warriors called the Patchamen kidnapped her, forcing Sky, Bloom, Brandon and Flora to go to Eraklyon to rescue her.

It is then known that she has been trained and taught for many years to become Sky's wife, and she is quite bitter at the fact that Bloom has taken her place.

Flora and Chatta console her, and tell her that she will find her prince someday, and that she should put her kingdom in front of her love life, to let them be healthy, and not worry so much and to be a great queen.

Season 3
In this season, she is invited to Eraklyon's one thousandth anniversary but she completely despises the idea of going, still bitter about Sky and Bloom's relationship. She is then spooked by Valtor who suddenly appears in her mirror and enters her room. Alarmed, she threatened to call the guards until Valtor offers his assistance to steal back Sky; he gives her a love potion. At the celebration, she gives Sky a goblet containing a drink that has been mixed with the love potion. Sky then falls under her influence. Under Diaspro's spell, Sky announces that Diaspro is his fiancée, which devastates Bloom and leads to the Winx demanding an explanation. Sky then believes Diaspro's lie that the Winx are actually Valtor's minions and orders his soldiers to attack them.

In "The Heart and the Sword", she is already planning out her and Sky's wedding. She is distracted by Riven while the Winx go inside the castle, so that Bloom can talk to Sky. Diaspro arrives sooner than they had expected and is shocked to see the Winx. She immediately orders the guards to seize them. After the Winx flee from the guards, Diaspro swears that Sky will be hers but is unaware that Stella had used her Fairy Dust to break Valtor's spell on Sky when he confronted them.

After that event, time passes. Eventually it is revealed by Sky that she was arrested by his guards and banished from Eraklyon.

Season 5
Diaspro is brought to Sky while he was conversing with Bloom by Princess Krystal, thinking that she could help him. Sky starts a conversation with Diaspro, and leaves Bloom. Stella comes to comfort her when she began to shed tears.

Diaspro also appears as an illusion caused by Tritannus's magic and she tells Bloom that Sky does not love her, however, Bloom was able to conquer the illusion and break free from it. Later, Sky tells Bloom that he really wanted to talk with Diaspro since they had a lot of history together. However, it appears that Diaspro only talked about herself, which made Sky think that she is really boring much to a relieved Bloom, who first suspected Sky loved or cared about her.

Later in the fifth season, she is seen at Eraklyon's castle with Samara. Erendor gave her the permission to bring him back. She interrupted Sky and Bloom's moment and made Bloom feel worried. At Domino, she continues to be a nuisance to Sky and Bloom's relationship and even opposed the union between the worlds much to Bloom's annoyance.

After returning back to Eraklyon, she called Bloom through Sky's phone and told her that all of Sky's calls from others must go through her and even advises Bloom not to call Sky at all. She knows that Bloom would call Sky, who is at the throne room, trying to convince his father to reconsider joining the union and so she goes there to mock Bloom for interfering.

Later when Sky and Erendor agreed to Bloom's request, she screams no and demands that Sky leaves. Enraged by her behavior, Erendor rips the emblem of Erendor off of her and announces that she is no longer needed. She then angrily blames Bloom and tries to leave but loses her balance and falls into the pool causing everyone to laugh.

Season 6
Diaspro makes her return in season 6 after her humiliating departure from the Tritannus incident. When Cloud Tower arrives on Eraklyon to terrorize another institute, Diaspro actually makes an appearance before the Trix. The Trix thought she was going to try to fight them, but to their surprise, Diaspro offers her assistance for their conquest.

Wanting to get rid of Bloom, she and the Trix hatch a plan against her. She reveals that she was invited to Daphne's coronation ceremony and if she is successful, the Trix might consider her an addition to their group.

On Domino, she arrives early and notices Bloom's weaker state. When the ceremony officially begins she hides amongst the crowd and continues to observe, she confirms that Bloom is much weaker than before and reports it to the Trix, to which they command Selina to summon the fire eaters. The fire eaters then begin to attack and while the others continue to fight them, Sky and Thoren quickly try to escort Bloom to her room, but Diaspro appears and lies that the best place for Bloom to restore her power is the Vortex of Flames, but Sky is able to see through this fraud. He is then attacked by one of the fire eaters and falls unconscious.

Diaspro then assures Thoren that she will take care of the creature, transforms and blasts it but complains about the hard work. She then directs Thoren to bring Bloom to the Vortex of Flames and drop her in there but Thoren hesitates. Seeing this she tries to reassure him again but Daphne and Sky come just in time to stop her. Seeing the two's arrival, Diaspro blasts Thoren knocking him out. She then levitates Bloom over the vortex and tells Sky he is not right for her. When Sky angrily reaffirms his love for Bloom, she drops her. She then proceeds to shield herself from an angered Daphne and disappears. She does not appear in the rest of the sixth season.

Season 8
In "The Wishing Star", Diaspro plans to try and get Sky back by going on a fake secret mission with him. She claims that they need to retrieve the lost medallion of Eraklyon that both she and him have been tasked to recover. Diaspro proceeds to drag him around the Magic Dimension for an extended period of time and it is clear that Sky is getting more impatient.

Their "mission" ends up on the star Monoceros. When Sky asks if this is the right place, Diaspro "affirms" it noting that it should be on one of the floating rocks. When Sky suggests spilting up to find it, Diaspro is sent into a panic, fearing he will realize there is no such medallion. She tells him that something could happen and because she is "sooo frightened!" Sky relents and innoccently asks the Monoceros Lumens for assistance when they inform them the floating rocks are only for the unicorns. Diaspro steps in and proceeds to explain that they are on a mission, tasked by the King of Eraklyon and thus, have the freedom to go wherever they so choose. This gets them on the bad side of the Monoceros Lumens and they attack them. One of the attacks knocks the map out of Diaspro's hand. She is busted when Sky finds it and is forced to tell him the truth.

Elsewhere, Diaspro is chided by Sky for taking advantage of his fight with his father. Their argument comes to a standstill as a angry Black Unicorn returns. Diaspro is taken to safety while Sky deals with it, only for his suit to be damaged by the unicorn. The Winx's unicorns soothes the Black Unicorn's anger and they all return to the ground. Diaspro intercepts the happy, encouraging moment as she now wants to head home. This in turn causes Bloom to get angry as Sky had been keeping this from her. Diaspro finds it amusing that this was enough to rattle Bloom. The Black Unicorn, Aryo, chooses to a bond with Diaspro and she leaves with it realizing her presence is not welcomed. She also does not hesitate to mention her excitement for the next mission with Sky, purposefully making it worse for Sky and Bloom.

Revenge of the Trix
After making her arrival to Red Fountain, Diaspro drags Sky to a more private room to inquire him about what he had just told her: that he loves someone else. Upon hearing this, Diaspro's eyes shine with fury, hoping that he had just told a joke, only to be told by Sky that he was serious. She tries to sway him back to her but he does not relent and stands by his words.

Diaspro is then confronted by Bloom who falsely accuses her of something she had no involvement in. Bloom then assaults her, causing them to engage in a heated battle that Diaspro ultimately loses, which leads Diaspro to latch onto Sky for comfort when he rushes over to her in confusion. It is then that Diaspro angrily reveals that Sky is her fiancé, devastating Bloom in the process. Unfortunately, Diaspro also sees that Sky cares more about Bloom than her and is greatly upset by the fact that Bloom was the one he fell in love with.
