Ámbar is a person who has never had to work for money. She is superficial and capricious, but also very intelligent. Ámbar is the type of girl that catches everyone's attention and is very popular. She will do anything to get what she wants and has friends to support her and her bad deeds.
When trying to get what she wants, Ámbar is mean, condescending, and manipulative. Despite all of this, she yearns for the acceptance of her peers and most importantly, her godmother. Although she won't admit it, she is jealous of Luna's relationship with her parents.
Although her jealousy may be explained in some way, her actions cannot be. She tries to sabotage Luna's life in an attempt to destroy the chance of any rivalry that threatens Ámbar's hold over Matteo's heart and her skating career.
After learning of her plans, Matteo quickly breaks up with her, causing her to be even angrier at times, but also learns to hide her hate towards Luna, dropping it all at once at the right moment.
Ámbar grew up with a life of comfort and luxury. Everything in her life seems to be under control until she meets Luna Valente. She is dating Matteo Balsano, but while she is in Cancún, she has trouble reaching him. She calls him many times, but Matteo ignores the calls and continues to skate with his friends. When Mónica Valente makes fish for Ámbar, she is displeased, so Miguel orders Foodger Wheels for her. When Luna delivers her food, Luna's skate gets stuck on her leg and Luna falls into a pool, Matteo goes in to save her, much to the displeasure of Ámbar.
Back in Buenos Aires, Ámbar meets up with her friends Jazmín Gorjesi and Delfina. She talks to them about what a pain Luna is. She goes to Jam & Roller and shows off her dancing/skating skills. Luna is impressed and tries to join in, but ends up annoying Ámbar. When Luna applies for a job at the rink, Ámbar loosens the wheels on her skates, and Luna ends up tripping.
Ámbar and Delfina are best friends. They are very much alike in personality as they are both rich, manipulative and don't like people messing with their plans. They often try to destroy Luna's life, along with Jazmín, but it doesn't always go to plan.
Jazmín and Ámbar are also best friends. Jazmín is a very supportive friend to Ámbar and is always there when she is needed. She also tries to help Ámbar destroy Luna's life.
