Cassandra (Tangled)

"I tried to warn you Rapunzel. You have to be careful of who you trust"

- Cassandra revealing her true nature

Cassandra is the tritagonist in the TV series spin-off of the Movie Tangled and it's prequel special Before Ever After. She initially starts off as a supporting character, serving as Rapunzel's Lady-in-Waiting and one of her closest friend but by the end of the second season, she eventually betrays Rapunzel by taking the Moonstone for herself so she could fulfill her own destiny and is set to become the main antagonist of the third season.

history
Cassandra is first seen waiting for Rapunzel's return from a ride with Eugene at Corona's village gates. From there, Cassandra takes Rapunzel to attend to the various duties of a princess, specifically in preparation for her upcoming coronation ceremony to officially crown her as heir to the throne. Rapunzel laments her feelings of stress of the pressures of royalty overwhelm her. Cassandra believes the princess should take a break regardless of what her father wishes, but Rapunzel refuses to do so. Later at a dinner event, Cassandra sits with Pascal, while Rapunzel sits with her parents, and Eugene sits at the children's table (an arrangement made by Cassandra, who was in charge of seating). Eugene takes the time to propose to Rapunzel, but due to her fears of being bound to life in the castle, Rapunzel rejects and leaves. Seeing the princess upset angers Cassandra, who glares at Eugene. She is Princess Rapunzel's best friend and who is also the adopted daughter of the Captain of the Guards. She has a strong dislike for Eugene, but eventually warms up to him and is also a highly trained warrior.

In Season 2, she joins Rapunzel on her journey to follow the path of the Black Rocks, but as the season gradually progresses, their friendship becomes increasingly strained and she ultimately turns against Rapunzel by stealing the Moonstone for herself, bonding with its supreme power and altering her hair and eye colors and attire in the process.
