Kind of, but we have better style.
- Main article: List of Nabu's Outfits
Despite his isolated childhood, Nabu is very social and friendly. He is upbeat, fun and enjoys life to its fullest. But he is also daring and intelligent, seeing as he ran away from home because he disapproved of the arranged marriage and even located Aisha and spied on her to know what she was like.
Nabu is a patient, kind, honest, understanding and rational person; he also does not get jealous. He shares these traits with Helia and both mediate between their friends who are having conflicts with their significant other, and especially Riven, whose personality is the opposite. Unlike Helia however, he is not shy. His patience is demonstrated when the Winx (especially Aisha) and Specialists were suspicious of him when he sneaked onto their spaceship. He patiently waited for the group to trust him and did not push them to do so. Nabu is also very true to himself and sticks to his beliefs, which included marrying someone he loved.
He is capable in adapting to situations and is a quick and rational thinker. Shown when he quickly thought of an excuse when the girls caught him spying on them and when he easily removed the shackles (due to the group's suspicions) and protected Aisha from a winged centaur.
Nabu is also very selfless and caring, seeing as he had sacrificed his own life for the Earth Fairies.
In the comics, he is shown to be naive, as a result as his isolated childhood, as shown with his relationship with Helisia and how he is even engaged to her, despite already dating Aisha, much to her chagrin.
Nabu was from the richest family of Andros. After clearing up some misunderstandings with Riven and showing him some battle moves, Riven inquired Nabu about these techniques. Nabu tells him that as a child, he had grown up on an island with no one his age and therefore lacked friends. For companionship he turned to the security guards there, spent time with them and learned all of their tricks. Though it was a time of loneliness which was similar to Aisha's childhood.
Nabu is first mentioned at the end of the episode "The Heart and the Sword", when Aisha sadly reports to her friends that her parents have set up an arranged marriage for her. Nabu first appears at the end of the episode "A Trap for Fairies", where he finally finds Aisha.
He later returns in "Valtor's Box", where he listens to a conversation between the Winx girls until Stella reveals his hiding spot. Later in the episode, he decides to offer the Winx his assistance in fighting Valtor, who plans to steal a magical item at the museum. Nabu does not want to reveal who he really is, so he tells the Winx that his name is Ophir. The Winx let him come along on the mission, even though they are not sure if they can trust him. However, when Valtor threatens Aisha, Nabu gets in the way and is captured by Valtor. The Winx are forced to give Valtor the magic box he came to steal in order to save Nabu.
Later, when the Winx went to the Golden Kingdom to obtain the Water Stars, Nabu was a stow away on their ship. Aisha discovered him, and since the group were uncertain of his trustworthiness based on their previous encounter, they put shackles on him. During the mission, Nabu and Aisha get to know each other a little better. Nabu helped the Winx fight off the guards of the Red Tower, and was the only one who did not get knocked out. Riven showed up shortly afterwards, and he and Nabu get into a fight due to Riven misinterpreting the situation and mistakenly believing that Nabu was trying to steal Musa from him. Sky and Timmy break up the fight, and the misunderstanding is cleared up. When the Trix later attack the group while the Winx (except Bloom) are inside the Crystal Labyrinth, Nabu at one point easily defeats Darcy.
In "The Wizard's Challenge", after having obtained the Water Stars, the Winx invite their boyfriends to a dance club and Aisha asked Nabu to come along. However, Nabu was forced to leave when his security guards showed up to bring him home. When he meets with Aisha again near the end of the episode, he explains the situation and finally reveals his true identity. He tells her that when a marriage was arranged between him and Aisha, he initially did not want to marry her and ran away from home in order to find out what she was really like, and therefore, began to secretly keep an eye on the Winx girls for awhile. He used a fake name, Ophir, in order to conceal his identity. After the clarification, Aisha asked about his true feelings and he confesses that he has fallen in love with her, and apologizes for lying to her. Aisha reciprocates his feelings. Later, Aisha and Nabu meet each others' parents, who have realized that they should not have forced their children to follow a tradition that went against their wishes. However, they are also pleased that destiny brought them together anyway, but decide that a marriage can wait. The episode ends with the Winx welcoming Nabu into the club.
In "Wizard's Anger", Nabu welcomes Aisha back from her mission.
In "A New Beginning", he joins the Winx and Helia on their mission to Andros to save the other specialists from Valtor. When they get there, the group decides to split up in order to save the Specialists. While Tecna, Stella, Musa, and Bloom are fighting the elements, Nabu, Aisha, Helia and Flora find the real Specialists locked up in a prison cell. After freeing the Specialists, Aisha and Flora go ahead to fight Valtor while Nabu and Helia stay behind with the Specialists, catching up with the others later.After the battle is over, and everyone is celebrating at Lake Roccaluce, Nabu and Aisha share their first kiss.
In this season, he proposes to Aisha, which she accepts despite the two already being engaged in an arranged marriage by their parents.
When he and the Specialists show up to help the girls fight the Wizards of the Black Circle in "Winx Believix", it is Nabu who saves Roxy from being absorbed by the Black Circle using his magic. However, during the fight, Nabu's magic is useless against Ogron.
When Diana shows up in "The Nature Rage", Nabu recognizes the sleep inducing pollen she uses to knock out the people in the Frutti Music Bar, and tells the Specialists to hold their breaths for as long as they can. Once Diana has left, Nabu uses his magic to weaken the magical roots she used to tie up the Winx, allowing them to regain their strength and transform. Nabu and the Specialists go to the Gardenia park to confront Diana, but Diana easily takes out most of the Specialists, only Nabu being able to put up a fight due to him being the only one with magical powers. Nabu manages to resist Diana's attacks, but is unable to do anything but watch as Diana and the Amazon Fairies kidnap the Specialists and take them away to Diana's kingdom.
When the Winx show up, he is clearly worn out from the fight against Diana, and informs them of what happened. Nabu apologizes for letting the Amazon Fairies take the Specialists away, and admits that he is not as powerful as a Major Fairy such as Diana.
When the Ethereal Fairies appear in the next episode, Nabu seems to recognize their powerful magic and comments on how awesome it is. He joins the Winx as they go to the Amazons to rescue the Specialists. When the Amazon Fairies show up, Nabu asks the Winx to distract them while he goes off to Diana's castle to save the Specialists. It is unclear what exactly happened to him while he was searching for the Specialists, but he was somehow injured and captured by the Amazon fairies.
At the beginning of the next episode, Aisha is clearly concerned about Nabu as his condition seems to be worse than the others, and demands to know what Diana did to him. Diana simply chains Nabu and the Specialists to the wall, and orders the jungle itself to help capture Bloom, Stella and Tecna who had gone off to search for the source of Diana's power.
After they have been captured, and Bloom awakens Sky expresses concern for Nabu as he was the only one who had not yet regained consciousness at that point. Bloom and the other fairies quickly combine their Sophix powers to break the chains, and Bloom uses her powers to heal Nabu. When the Amazon Fairies return, Nabu uses an illusion spell to distract them while the Winx knock out the Amazon Fairies, allowing them all to escape the castle.
In "The Day of Justice", he makes an attempt to cure Duman's illness after Sibylla's fairies had failed. He realized that the reason they were unable to do anything, was because they did not know what the cause was. He soon finds out that the cause of the illness was that Duman's magical energy had gotten unstable. However, soon after this discovery, Duman transforms into a monster and attacks the other specialists, and ends up capturing Nabu. Riven ends up chasing down Duman, and manages to save Nabu.The Specialists end up having to fight Duman, who blurts out Ogron's plan to capture the Earth Fairies. Nabu manages to defeat Duman, and he and the specialists go to warn the fairies, but arrive too late. Nabu decides to close the shadow abyss, despite Aisha's warnings. Nabu succeeds in closing the abyss, but uses up all of his energy and passes out shortly afterwards. Aisha attempts to use the last gift of destiny to revive him, but Ogron takes it from her and wastes it on a flower. It is unknown if he died because Aisha attempted to use the last Gift of Destiny on him, or he is in a deep slumber as Queen Morgana said. After the final battle with the Wizards of the Black Circle, Morgana tells Aisha that she will watch over him, until he wakes up.
Nabu then appears in "The Shimmering Shells", appearing in Aisha's inner problem. As a mere illusion of Aisha's problem, he cruelly comments on how Aisha had let him die, a comment that hits her very hard as she is still trying to move on from losing him. She is eventually able to overcome her inner problem.Aisha however, continues to miss him, as she is in seen looking at his picture longingly on her phone.
Nabu has demonstrated his range, versatility and power in magic. His true source of power was never stated, but has shown to affect all sorts of materials, objects and even people. He can disappear, create clones of himself, solidify materials such as plants, form defensive shields, manipulate and transform objects, strengthen a car engine and many more.
Alongside his mystical abilities, he also knows self defense tricks which he learned from the security guards. He applies these tactics with magic, further demonstrating Nabu's great range of skills. He has shown these examples to Riven after the latter expressed his curiosity. He is also shown to be proficient in espionage.
Because he too can duplicate himself, Nabu can easily distinguish between clones and the real person. This was showcased when Darcy unleashed her duplicates to confuse him, Nabu followed suit and quickly deduced which one was real.
