1985[]
The teenage Dark Princess lives inside of an isolated castle with her minions. Very greedy and used to always getting her way, she demands to have the diamond planet, Spectra, for her own. If this planet were to be removed, the universe and everything in it would die. Despite being warned of this countless times, however, the Princess proceeds to capture it anyways and has her henchmen build a giant spider-legged ship capable of trapping Spectra inside of a net.
Rainbow Brite and her newly acquainted friend Krys venture to her lair to stop her, but upon arriving, the Princess steal's the heroine's magic belt and uses her powers to banish the two of them shortly after. The duo manage to return to her once more and a battle is waged. The princess gets the upper hand, but only for a brief moment, as Rainbow Brite's other nemesis, Lurky, who had also been seeking the diamond planet, accidentally crashes into her throne room with his ship. This distraction is just enough for Krys and the heroine to destroy the crystal which acted as the source of the villainess's power.
Enraged, the princess makes one last ditch effort to steal Spectra by hopping into her ship, but runs out of fuel just as she reaches its atmosphere. She then determines that if she cannot have the diamond planet, no one will, and prepares to shatter it into a billion pieces by launching the ship directly into it. However, Rainbow Brite manages to use her magic in the nick of time, and the Princess's ship explodes in the sky.
1986[]
Despite what it appeared, the Princess managed to somehow survive the ending of the film but has been left with no magic powers. She comes to Rainbow Land with Count Blogg after hearing that there are diamonds located in a certain cave. Once she has them, she reasons, she can re-energize her powers and get revenge on Rainbow Brite. She fools the sprites who had been mining the cave into thinking that she is their queen, and has Blogg randomly abduct and then pretend to transform several them into a frog to ensure the compliance of the others.
Rainbow Brite is shocked to learn that the Princess has come to her homeworld, but by the time she encounters her, the villainess has already regained some of her power. She threatens the heroine, saying that she's going to transform her into a diamond to wear around her neck. Nevertheless, Rainbow Brite manages to defeat her once again, and banishes her and her ship from the land.
