Henna

Henna is the main antagonist in Barbie: Mariposa and her Butterfly Fairy Friends. She is a butterfly fairy voiced by Nicole Oliver.

Story
Henna wanted to take over the city of Flutterfield and rule it as queen. She was originally Queen Marabella's attendant. She poisoned the queen so that after two days, she would die, and Flutterfield would be in danger; Queen Marabella was a magical fairy who put lights in the trees in Flutterfield. Skeezites, creatures who wanted to eat butterfly fairies, were kept away by the lights. They would go out if Marabella died.

Henna teamed up with the skeezites by telling them they could eat as many butterfly fairies as they wanted when she was queen. Prince Carlos the queen's son, informed Mariposa that she needed to find an antidote for his mother. Mariposa left Flutterfield, found the antidote, and saved the queen. Henna escaped with the skeezites and wasn't seen again.
