Nexsha

Aisha x Nex is the het ship between Aisha and Nex from the Winx Club fandom.

Season 6
Nex is introduced in "The Flying School". He becomes interested in Aisha after she scolds him for knocking Roy, a Specialist with a crush on her, out of the arena during a training match. Her strong attitude impresses him. The two boys compete for her affection throughout the season. At first, Nex does not play fair and is too aggressive against Roy, which makes Aisha and her friends suspicious of him.

Despite this, she starts to show a slight, but not yet romantic interest in him in "Bloomix Power". She compliments him for completing the obstacle course in the Alfea Gym quickly. And even after yelling at him again for kicking the final hoop away on Roy's turn, she hesitates to leave for the mission to free Linphea College without him.

Nex regains the group's trust by helping them save the Linphea students. He also tries to protect Roy and Aisha from a basilisk, but he ends up getting turned to stone. Aisha shows concern for him for the first time by screaming in horror. (Stella changes him back with her Ray of Pure Light spell.)

In "The Lost Library", Nex tries to say goodbye to Aisha before the Winx's trip to Egypt, but he is too shy and stumbles on his words. She snubs him, then Roy interrupts and draws her attention away by giving her a gift. Nex gives up and walks away disappointed.

A few episodes later before the Winx enter the Alfea Greenhouse, Aisha and Nex are seen standing together and talking. This may be when they began to feel comfortable around each other. By the next episode, she is friendlier to him.

Nex and Roy come to cheer her up after a fight with Stella. When Roy suggests rollerblading, the Paladin challenges her to a race. She perks up right away and creates a floating rink for them out of Morphix.

After she wins, Roy makes her blush by complimenting her on her abilities. Nex gets jealous, but this time he stops himself from acting out against him. Instead, he suggests jumping off the rink together, which Aisha eagerly agrees to, and they hold hands as they skate to the edge. Aisha almost falls when she lands, but Nex catches her. This seems to impress her, as she lays her hand on his chest and compliments him.

The two grow much closer during the Winx's mission on Calavera Island. They spend a lot of time surfing, chatting, and swimming together, and he sees her off before the Winx enter the Legendarium World. While the group is fighting the pirate zombies, a zombie tries to attack Nex behind. Aisha warns him and tries to save him, which shows she has started to care even more for his well-being.

Aisha and Nex team up against Chevonne of the Water in "Legendary Duel". He distracts her while Aisha sneaks up and attacks her from behind. They are unable to destroy her, but they are still proud of themselves for their teamwork and spend a moment smiling at each other.

Later, Icy blocks Aisha from going to Pixie Village to free the Pixies from the Legendarium World. Nex stands up to her. She hurls a beam of ice at him and Aisha panics, but he hits it back with his halberd and knocks the witch out of the way. Once they reach the village, Aisha praises him for his courage. He wishes her luck on her mission and waits for her with the Winx's bonded Pixies.

As the Pixies celebrate their freedom, Aisha shyly admits to Nex that she was scared when Icy attacked him. He smiles at her, takes her hand, and confesses he was worried she would never return from the Legendarium World. This scene seems to establish them as a couple, but it is not confirmed until the next season.

Season 7
Aisha and Nex are officially a couple by the beginning of the season. (Roy does not appear at all in this season.) When the Specialists attend the opening celebration for the Alfea Natural Park, Nex is with them. He helps the group search for the animal with the First Color of the Universe and protect all the Fairy Animals when a giant tortoise goes berserk.

In the next episode, Nex gives Aisha some words of encouragement before she goes to prehistoric Magix. Aisha assures him she will return in time for their date. That evening, they go out to dinner at the same restaurant Tecna and Timmy visited in Season 5.

Just as Aisha and Nex are about to kiss, Squonk (Aisha's Fairy Animal) drops between them from the ceiling and Nex ends up kissing him instead, making the Specialist jump back in shock as Aisha laughs. She introduces Squonk, but Nex does not like him.

Few episodes later, Nex and Squonk began to like eachother and Nex realized he's okay with Squonk now.

Season 8
The Winx and Nex visit Aisha’s realm, Andros, to celebrate the founding of its kingdom. During the festival, Valtor’s helper Obscurum attacks Gorgol, the suboceanic star of Andros. After transforming into Sirenix fairies, the Winx, aided by Nex, embark on an underwater mission to save the star.

The Winx engage in battle after Obscurum tries to break the core, though the misfired attacks that hit the sides of the cave they are in cause the cave to close them in, traping them whil Obscurum and th staryummies escape. Anemones start attacking the Winx, causing everyone but Aisha and Nex to faint. The couple notice Gorgol's Lumens escaping and chase after them. Thanks to the Lumens, they realise that their attacks aggrevated the situation, and what they have expereinced are natural reflexes. Aisha and Nex try to solve the problem, though fail as Aisha instead attacks the cave directly, causing Nex to get stung and faint. Aisha realises that the song the Lumens can sing are required the deactivate the safety mechanisms, and convinces the Lumens to sing it to allow the rest to be freed. The situation deescalates, though the girls still have yet to rekindle the core. Aisha comes up with an idea to surround the core with her Morphix, creating a pocket of air which will allow the Winx to go into Cosmix mode to use their special abilities to restart the core. Outside, They admire the star, which thanks them for restoring its powers.
