Original appearance: 12 years old, Caucasian, blue eyes, blonde hair, average build.
Wears a blue skirt and blouse with rainbow colored sleeves, rainbow colored boots. Red star emblazoned belt that hold her star-sprinkles and red suspenders.
Changed appearance (IMO): older now, athletic build, same hair and eyes. Keeping true to her eighties roots she would be busty but not overly so. Hair not in a bun, but longer and tied into a ponytail.
Her uniform retains the same blue primary with a matching skirt and blouse. The outfit would be a leather armor though. The red belt now is more of a sash the holds a shoulder piece in place. Her sleeves still have the same color scheme but are more form fitting and of a type of cloth instead. She would have grieves that are a red primary with yellow accents. The skirt is pleated white cloth with leather strips hanging over the underskirt.
Special Abilities/Powers/Skills: one power for each color of the rainbow.
Red: super strength
Orange: kinetic absorption (defensive that refills her power bar, still takes damage though but only usable while blocking)
Green: healing factor
Blue: plasma manipulation
Indigo: force field creation
Violet: emotion control (charm like technique only usable in a grab technique)
Her body, or body part, glows the color of each power used, can combine colors but takes up a lot more energy. Exceptions are green and indigo, as she has to concentrate more to do so. Also retains her rainbow beam but now can be weaponized into a powerful concussive blast.
Story: Whisp was a young orphan girl that was given a great responsibility. She was to be the protector of the Color World and bring color back to the land stopping the evil Murky Dismal. She succeeded with the help of her friends the Color Kids and her trusty steed, Starlite.
To give her the power to color the world she needed what are called star-sprinkles. Being the fact that she is human, star-sprinkles had an unusual side effect after so many years of exposure. She became blessed with super human abilities one for each color of the rainbow. She used these newfound powers to help aid her in her quest.
Murky however was not happy with this turn of events. He joined forces with the most powerful villains in the land and together created an army. They laid waste to the land, pushing Rainbow Brite and her friends back. The war that was to follow lasted for many years.
Then one day as the sun rose all the men in Color World did not. Shocked by this Rainbow, and instead of taking advantage of this and winning the war finally, she took to the skies to find the source of this affliction.
