*Princess Bloom is the Fairy of the Dragon Flame. She is Prince Sky's fiancée, the second princess of Domino and its Guardian Fairy. She is one of the founding members of the Winx Club, where she is recognized as the leader of their group, which also signifies her status as the central protagonist of the Winx Club series as a whole. She is also an alumna/student of the Alfea College for Fairies as of The Secret of the Lost Kingdom.

Bloom is a slightly fair-skinned girl with waist-length red-orange hair with a single small hair strand sticking up (until Season 4) and large cyan eyes.

Civilian Winx Club In Season 8, Bloom's hair is worn down (just like her original form from Season 1-4), but her bangs are much more side-swept and curly to the right side. She wears a multi-layer dress similar to her Enchantix, but in shades and layers of pale blue and white. There are several ruffles at the end of each layer, embroidery decorations throughout the dress and two small brown bows at the end of the penultimate layer. She wears a blue coat over her dress and blue leggings similar to her Sirenix and Bloomix with a pale blue flower pattern. She wears brown country-style boots at the calf with various ruffle decorations. She wears a bracelet on her left wrist and a necklace with a pendant in the shape of a pink heart.

Bloom started off as an insecure girl at the beginning of the series because of her ignorance of her true origins and her strange, yet surprisingly potent powers. Later on, as she learned more about magic and herself, she grew increasingly curious about her past and whom her biological parents are. An escapist by nature, she has a tendency to run away when things get too hard or confusing for her, and can also be impatient and stubborn, with a short temper. Bloom was also impulsive at times, which led to some very bad experiences for both her and her friends, especially when she first met/attacked Diaspro under the assumption she was one of the Trix with a lack of evidence. Her greatest strength and greatest weakness was her status as the guardian of the Dragon's Flame. While the Dragon Flame made her arguably the most powerful fairy in the Magic Dimension, it also consistently drew numerous enemies to her such as the Trix, Darkar, Valtor, and the Ancestral Witches. Additionally, Bloom is has been known to make some selfish decisions (though this is partly due to her strong desire to learn her background) and can act rather self-centered at times.

Despite her flaws, Bloom still has a heart of gold. She cares for all of her friends, allies, and families (both adopted and biological) deeply, and is always willing to help and fight for a good cause. She has shown herself to be selfless, caring, brave and a true capable leader. Bloom is tough when needed to be and always lends a helping hand to people in need. As she grows in later seasons, she becomes wiser, and a far more focused and effective leader to the Winx, as a part of maturing over the years, and has (for the most part) learned to reel in her impulsive and temperamental nature. This is especially relevant in World of Winx and later seasons, where Bloom showcases her much more serious, but still kind-hearted disposition as leader of the Winx.

Fairy Forms As the keeper of the Dragon Flame, many of Bloom's Fairy Forms maintain a theme of fire. Blue stands out as the primary color of a majority of her forms, with pinks and purples acting as accents.*
