Appearance
Her eyes change color to yellow, with cat-eye pupils, while her eyeshadow became dark violet. Her still-sparkling Winx outfit is somewhat dark blue instead of the usual cyan. The tiara becomes silver and pointed, and the brooch on her shirt turns dark purple. Bloom's waist-length dark orange hair becomes thicker and a darker shade of red while her wings become dentate and cyan with gray tips.
In the Nick form (The Shadow Phoenix special), Dark Bloom wears the gothic clothing style– she wears navy black leggings and her outfit only changes color. Her brooch's shape, her tiara's shape, her boots' shape does not change.
Personality
While in this form, she is very negative and does bad deeds (heartless, abusive, unwilling, mean, selfish, manipulative, mischievous, cruel, and uncaring) and obeys Lord Darkar loyally. For example, she steals the Codex fragment from Alfea for Darkar. She only made one other appearance in the Season 2 finale, when Darkar discovered that he needed both the powers of light (which is the Dragon Flame - the very source of the Great Dragon's power) and darkness to claim the Ultimate Power of Realix.
Thanks to her friends - and mainly link saying he loves Bloom more then anything - Bloom heals her friends and herself with her pure heart, returns to normal, returns the Ultimate Power to Realix, and joins her friends in a Charmix Convergence that banishes Lord Darkar back to Lord Darkar's Fortress.
