The Trix

The Trix are the main villainesses of the series. They managed to "steal" Bloom's power, The Dragon Flame until Bloom, with Daphne's help, realised that she had never lost her powers, but was unable to use them because of her doubts, and therefore regained her powers and defeated the Trix. They were arrested and sent to the Fortress of Roccaluce in the end of the first season, but they escaped with the help of Lord Darkar in the beginning of the second season. He gave them their Gloomix which multiplies their strength and magical abilities tenfold. In the third season, they worked with Valtor. He gave them a power-up called Disenchantix, which is the opposite of Enchantix. They made a comeback in the second film as minions of the Ancestral Witches. The Trix returned in the fifth season and gained Dark Sirenix that Tritannus stole from Daphne and gave them. They are the main villains again in the sixth season, at the end of which, they are locked inside the Legendarium book for good. In the Seventh Season of the Winx Club the three witches return back into the real world after Brafilius finds and unlocks the ultimate power and accidentally releases the Trix from imprisonment in the Legendarium world. In the episode 22 of Season 7, the Trix kidnapped Brafilius and they take revenge on the Winx for trapping them then they were defeat by the Winx in the finale episode

Icy: The leader and the oldest of the trio. She is the witch whose powers are derived from ice, snow, frost and sleet, which starkly contrasts with Bloom's powers deriving from fire. She enjoys torturing fairies and despises Bloom and the Winx. Therefore, she is most competitive with the girls for the whole series. In comparison to her sisters, she is more aggressive than Darcy, but calmer than Stormy. She has bluish white hair, and has a dark teal hair tube piece in her hair that ties it into a high pony tail with three ice blue diamonds on it and a blue outfit with an 'I' in the middle and dark blue boots. In season 2, Darkar gives Icy a light blue necklace (Gloomix) that makes a perfect shape around her neck then makes a wider circle shape and ends with a diamond. Icy is also given the form Disenchantix in the third season, as do Stormy and Darcy. Her boyfriend was Tritannus. In Magical Adventure, Icy says she can take on one fairy with her eyes closed but Belladonna tells her to keep them closed because there are six fairies and that Bloom once took on Icy in the Season 1 finale.

Darcy: The second oldest of the trio. Darcy derives her powers from shadows and darkness. She enjoys tormenting pixies and is less aggressive than her sisters, preferring more subtle and manipulative techniques. Darcy hypnotized Riven, getting him to turn on the fairies, for most of season one. In season 2, Darkar gives Darcy a bracelet (Gloomix) that goes on the back of her hand to her elbow, which is indigo on her left hand. She has long, brown hair and light brown bangs falling through her sides and an indigo outfit with a 'D' on it, she is sometimes seen with glasses.

Stormy: The youngest of the trio, she has power over the weather, such as thunderstorms, hurricanes, tornadoes, and lightning blasts. She is the most hot-tempered of the group and is prone to violent outbursts. She enjoys tormenting both, fairies and pixies. She often does not think before she does something, which can often lead them to dangerous consequences. Stormy is Musa's rival for most of the series. In season 2, Darkar gives Stormy a bracelet (Gloomix) that goes on the back of her hand all the way up to her elbow, which is violet on her right hand. She has bluish-lavender hair styled in a cloud-shaped hairdo with light bluish-lavender colored bangs in a lightning bolt shape and a reddish-violet outfit with an 'S' on it.
