Morgana/Series

Pre-Series
For centuries, Morgana and her fellow fairies roamed the Earth freely as magic remained plentiful throughout every part of the planet. Ruling as Earth Fairy High Queen, Morgana eventually grew tired of her lifestyle and curious of the humans', so she left to live in their world temporarily, during which she found that there exists people who can be special even without the need to use magic.

Years later, Morgana met a young man named Klaus, who she fell in love with and later married. Shortly afterwards, the two of them had a little daughter they named Roxy, and though Klaus was unaware of it, Morgana knew Roxy was born a fairy and, therefore, the Princess of Tir Na Nog. Despite that though, Morgana lived joyously with her family to the point where she was even ready to leave her kingdom and hand her crown over to another fairy until she was suddenly attacked by the Wizards of the Black Circle.

Morgana tried to fight them off but ended up being sealed in her own kingdom, whereas her daughter, Roxy, was too young to showcase her magic, making the Wizards incapable of feeling her presence until it would properly manifest when she got older. This would only later stall the Wizards, who would spend the next couple of years searching for the final fairy they were missing, leading them to Alfea, where they would attack Bloom believing her to be the fairy that escaped their grasp, as both she and Roxy were raised in Gardenia. However, before leaving Gardenia entirely, the Wizards wiped all of Klaus' memories of Morgana, making him believe that he always raised Roxy and Artu alone so that no one would become suspicious of Morgana's disappearance.

While trapped within her kingdom, Morgana was able to watch over her husband and daughter telepathically to ensure that they were well, but could neither return to them or make them realize that she was always in their lives. When the Wizards reappeared in an attempt to capture the last Earth Fairy, Morgana used her magic link with Roxy to help her believe in herself, her abilities and her fairy heritage. She also helped Roxy understand her powers as the Fairy of Animals and the power of the White Circle, which contained the magical powers of the Earth Fairies.

Season 4
When the Winx Club arrived at Tir Na Nog to free them with the help of the White Circle, Morgana was more than outraged with the fact that when Fairies roamed the Earth humans revered them, and after the Evil Wizards trapped them, they were all but forgotten and left in children's stories. With the prodding from Nebula, she contacted Diana and Aurora to wage war on humans as a vendetta. The only major fairy who did not seem to be swayed by the vendetta was Sibylla who, being the Major Fairy of Justice, was forced to remain neutral and could not take sides even in case she would want to.

Morgana was moved by Roxy's feelings to make peace between the humans and Earth Fairies (and possibly the fact that she knew Roxy was the daughter she had by marrying a human), and slowly attempted to stop Nebula and the other Earth Fairies. But, Nebula trapped her in a magical mirror in the Tir Na Nog throne room to usurp her power after the Wizards' treason by putting up a pretense of submitting to Morgana which ended with Nabu in a death-like state and almost sent the Earth Fairies to the Great Abyss. Only Roxy could free Morgana, since the mirror in which she was imprisoned could only be controlled by the heir to the throne of Tir Na Nog; Morgana finally revealed to Roxy that she was her daughter. It is probable that Morgana did not want to reveal that Roxy was her daughter because she was afraid the Wizards would find a reason to make Roxy suffer even more, or that they would be even more pitiless towards her than they had already been in trying to capture her.

In "The Day of Justice", when Morgana tells Roxy that the Royal Castle of Tir Na Nog is now and forever her new home, she tells Morgana that her heart will always remain at Gardenia, with her family. She then uses her magic to create holograms of Klaus and Artu when Morgana eagerly asks her if she has any pictures of her family, at which point Morgana seems melancholic. It could be that the fact that she was missing her family also motivated Morgana at the end to stop the fairies' vengeance against the humans, as she had once loved and married a human, and this may have reminded her that not all humans were bad.

During the ceremony where the Wizards were supposed to submit to the authority of the Earth Fairies, Morgana puts the Black Circle on her finger, which caused an abyss to open, and threatened to suck in all the Earth Fairies but it was closed by Nabu who, however, drained all of his energy in the process and went into a coma-like state. Morgana promises Aisha that she would take care of him till he wakes up again. After this the Earth Fairies lost faith in Morgana's ability to rule and Nebula ends this by overthrowing Morgana and imprisoning her in a magic mirror, and proclaimed herself as the Queen of Tir Na Nog, with Aisha as her second.

Roxy sensed Morgana was in great danger and the Winx came to rescue the Fairy Queen but Bloom, Stella, Flora and Roxy were defeated by Aisha and Nebula, the leader of the rebel Fairies, showed them Morgana imprisoned, and told them that after defeating the Wizards she will take control of the human world and tried to imprison the Winx inside the mirror with Morgana but Musa and Tecna saved them. Nebula, Aisha and the Fairies of Vengeance went into the Omega Dimension, where Ogron, Anagan and Gantlos had fled, to punish the Wizards. When the Winx could not find a way to free Morgana, she told them that only a Fairy Queen could free her, and that Nebula is not the only one who has control on the mirror since she is not the rightful Queen of Tir Na Nog. She revealed to Roxy that she is her daughter, and Roxy freed Morgana from the mirror.

Once freed, Morgana and the Winx went into the Omega Dimension, where Morgana defeated and disarmed all the Warrior Fairies, and convinced them to stop their revenge, and told them that she was ready to step down as Queen and allow Roxy to rule, as a better Queen, once she has grown up, and asked Nebula to return home and become the Fairy of Peace again, telling her that the world needs her. Unfortunately, Nebula and Aisha refused and tried fighting the Wizards but were overpowered. However, thanks to the appearance of the rest of the Winx and of Roxy, they were able to with their Believix magic convergence spell, defeated as well as froze solid, the Wizards for good.

When the Wizards of the Black Circle were defeated, Morgana chose Nebula to replace her as the Queen of the Earth Fairies. She then returned to her husband and daughter. Upon arriving home, Klaus could not remember her, since the dark magic of the Wizards had erased her from the memory of all the humans who once knew her, but with the Wizards of the Black Circle defeated and frozen solid in the Omega Dimension, Morgana was able to restore his memories back.

She is last seen nodding to Klaus as he serves his customers and enjoying a drink at the Frutti Music Bar.
