“Her hair leaves ten minutes after she does. That girl has to do something about those split ends. Ouch!”
Ruby is a character who appears in the Disney Channel animated short series, Descendants: Wicked World. She is the daughter of Rapunzel and Flynn Rider , has an older sister named Anxelin and according to Audrey that she has long, blonde hair that leaves the room ten minutes after she does. Her hair is shown to be prehensile, as it slapped Audrey after she picked it up.
When Audrey tell everyone that she wasn't voted The Queen Of The Neon Lights Ball, she seem to brushed Ruby hairs, when Mal ask her if she was brushing Ruby Hair, Audrey tell her sarcastically it wasn't Ruby but a other girl with pony tail, and she was stress brushing.
In the web series School of Secrets, there is a character known as Anxelin who is also the daughter of Rapunzel. There's a possibility that they might be sisters. She made a brief appearance and her hair slaps Audrey's face and then she walked away.
Ruby is the third new character to appear on the show though we never see her other then her hair.
Her appearances, usually her hair, serves as a running gag throughout the series.
