*Desiree is a genie-like ghost who wanders the world granting anyone their deepest desires, but manifests them in the worst way possible. The more wishes she grants, the more powerful she becomes (Only during Memory Blank). She’s one of the few ghosts in the series to have had an explicitly established human life on Earth. She's the main antagonist of the episodes "What You Want" and "Memory Blank."

Desiree is a tall, beautiful and green-skinned ghost with an hourglass figure, red eyes, long and thick black hair that is slightly messy at the bottom, and wears plum lipstick on her lips. As per being a genie, she has no legs and sports a wispy blue tail.

For attire, Desiree's outfit is mostly Arabian attire, which consists of accessories that includes a blue headband with beads on her head, a large, metallic grayish-purple choker with oval-shaped pendants, and four metallic cuffs the same color as her necklace; two of them around her wrists and two of them around her biceps. The cuffs on her wrists are also followed by three blue bangle bracelets; two of them on her right wrists and one on her left wrist, with the bangles and her headband match the color of her tube top with grayish-purple trim at the top. She also wore a large metallic, grayish-purple belt with a blue jewel placed on the center, hanging over her tail.

When she was alive, Desiree's appearance is exactly the same, except she was brown-skinned with turquoise-blue eyes. Her outfit back then is shown to be similar, only it sported a fuchsia-purple/golden color scheme, and due to the fact she still had legs, she dons harem-pants.

Desiree is a rather vindictive genie. Her wishes reflect this as they often have grave consequences beneath them, such as Sam's absent minded wish of never meeting Danny coming true, with her memories still preserved while nobody else recognizes her. Another time is at the Swap Meet where she makes a little girl's wish for cotton candy come true by turning the cotton candy stand into a volcano that creates a cotton candy tsunami which decimates the Swap Meet. She also uses the wishes of others to her advantage.

Her love tragedy gives her a rather low opinion of men; she refuses to let any man/men touch her unless she wishes it. However, this low opinion is misplaced given as how it was never the Sultan that resulted in her downfall, it was his jealous wife. This actually becomes obvious since he was clearly sad when she was banished.*
