Dark Bloom

Officially known as Dark Bloom - when Bloom turned evil due to Lord Darkar's diabolical influence on her - her eyes change color to yellow, with cat-eye pupils, while her lipstick and eyeshadow become purple. Her still-sparkling Winx outfit is somewhat blue-black instead of the usual cyan. While the tiara becomes pointed, both the tiara and brooch turn dark purple. Bloom's waist-length dark orange hair also becomes thicker and a darker shade of red while her wings become dentate and cyan with gray tips. While in this form, she steals the Codex fragment from Alfea for Darkar. She only made one other appearance in the season two finale, when Darkar discovered that he needed both the powers of light (which is the Dragon Fire-the very source of the Great Dragon's power) and darkness to claim the Ultimate Power of Realix. Thanks to her friends — and mainly Sky declaring his love for her — Bloom heals her friends 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 Shadowhaunt.
