For Raquelle, excess defines her posh lifestyle. Roughing it is not having a butler. The only thing to put a crack in her diamond sheen is Barbie. She dreams of catching her Malibu neighbor in a fashion fail and posting the pics on the web. She also wouldn’t mind stealing her boyfriend.
Raquelle has a complicated relationship with Barbie and the two can be considered to be "frenemies". Raquelle envies Barbie's fame and friendliness and often tries to show to other characters that she is better.
Raquelle has an unrequited crush on Ken and, in a number of episodes, attempts to prove to him that she would be a better girlfriend than Barbie.
Raquelle is the twin sister of Ryan. She is the more clever (or devious) sibling and will often use her brother's crush on Barbie as a method to get him to do things for her.
Raquelle and Nikki dislike each other, with the latter character seemingly being the only one who notices how mean Raquelle can be. She has yet to fully interact with Teresa.
Raquelle acts indifferent towards Midge. She sarcastically comments on Midge's finicky needs in Perf Pool Party.
Raquelle and Summer don't like each other, as seen throughout the course of Mall Mayhem. Raquelle goes so far as to lie about her feelings towards Barbie to prove to Summer that she is the better friend. The two may have possibly made up following their harassment by the Mall Cop.
Raquelle's name is an alternative spelling which is also the French spelling of the name Raquel. It is also pronounced the same way.
Raquelle's alternate name "Raquel" is also a Spanish and Portuguese name of the the Hebrew name/Arabic name, "Rachel".
In the Japanese dubs of the webisodes ofBarbie: Life in the Dreamhouse, her name is Rakueru (ラクエル), instead of Raquelle, the first time her name is anything but Raquelle, and her ラクエル is an alternative spelling and alternative pronunciation of ラクル (Rakeru), which Raquelle is an alternative spelling of Raquel, so it goes. As said before, this is the first and only time Raquelle is called a name that is not Raquelle.
Raquelle is the usually villain or antagonist in the show.
Raquelle and Ryan have similar roles to Ann and Alan from Sailor Moon, with the exception of being real siblings and not misguidedly evil. Raquelle crushing on Ken who loves Barbie is similar to Ann crushing on Darien who loves Serena and Ryan crushing on Barbie who loves Ken is similar to Alan crushing on Serena who loves Darian. This fact about the two being siblings in love with the a person who is in a couple to the other sibling loving the other one going out with that person as the opposite sex may or may not be a reference to that.
