Attie was born as royalty, being forced to participate in royal affairs all her life. She never left the kingdom until she met Finn because she had no friends and therefore no reason to. She lived in the Lake Castle with her mother and father before moving in with Marceline. Her father denounced her royal status and title in "Kicked Out", also depriving her of her royal gems, contacts, dresses, and maid-servant.
Like most people residing in the Lake Kingdom, Attie has pale, turqiouse skin and blue, water-like hair. When she debuted, her hair was down to her waist. By "The Front Gates", it had reached her knees. In "Kicked Out" and "The Christmas Album", it was down to her ankles. She had it cut to shoulder-length in "Roommate". It had grown back to waist-length by "The Vampire King". She had it cut to shoulder-length again (though a slightly different style now) in "Call the Midwife". She is a little bit shorter than Finn. She used to have a royal blue gem, much like her fiery counterpart, in her forehead. She wore contacts until her father took them, and she now wears a pair of thick, black glasses. She wears a different outfit in every episode that she has a major role in and even for some of her minor roles. Her gender-swapped counterpart looks the same but with straight, shoulder-length hair, a blue outfit very similar to Prince Gumball's pink one (minus the crown), and a more masculine build. In the Wut-Wut High timeline, Addeline had dark hair and normal-colored skin.
