Cassandra is a major character in the Disney animated series, Hercules. She is a close friend of Hercules' and to a lesser extent Icarus, who is hopelessly in love with her, during their time in Prometheus Academy.
As a result of her constant visions of doom and inability to prevent them from coming to pass, Cassandra is permanently gloomy and deeply anti-social. However, she does find some pleasure in her funny, cunning, sarcastic comments, which are always there when someone makes a mistake. That said, Cassandra is very loyal to her friends, and often acts as a mentor for Hercules in times of need, bringing patience to Icarus's 'Icarus-ness.' Cassandra is not opposed to lying to get out of things she would rather not do (dates with Icarus being the prime example of this). Cassandra has claimed that she has no interest in having children, she has been shown to be surprisingly good with kids.
Cassandra lives with her father Vic and her mother Evelyn. In contrast to their daughter, Vic and Evelyn are perpetually cheery and being chummy with Icarus, much to Cassandra's dismay; although in "Hercules and the Parent's Weekend", it's shown they can be just as gloomy as their daughter. After graduating from the Prometheus Academy, Cassandra would eventually become the most famous Prophet in all of Greece.
Powers and abilities
Cassandra has the involuntary ability to see the future (usually disasters), but is cursed so that no one ever believes her. When Cassandra has a vision, her eyes turn green and swirl around. A running gag is that when Cassandra makes sarcastic comments, Hercules and Icarus listen, but when she has visions, they rarely believe her. In Greek Mythology this is called the Cassandra truth.
