First Appearance (Xianghua in Rockoland) Giant Curses!
Xianghua in Rockoland Portrayer Debra Jean Rogers (as Debbie Rogers)
"You need to leave, Crash Gordon, or face our wrath!"
— Cassandra to Crash Gordon, after rescuing Seong Mina and Alisa from sinking in quicksand.

Cassandra Alexandra is Sophitia Alexandra's sister and Pyrrha Alexandra's aunt. She came to Rockoland just to stop the evil Crash Gordon.

Cassandra is also one of Rock Buddy's friends. She is also friends with Evil-Man, even though she is always falling asleep to infuriate him. The Rocko Squad is a great friend for Cassandra, but her best friend is Raybot.

Out of all of the Xianghua in Rockoland characters, Cassandra is the one of the two characters to cry prior to the first episode of the show (the other character is her niece, Pyrrha). In the case of Cassandra, she cried in her Soul Calibur III ending while saying that "I don't know how to fix it...".

Cassandra was the second character to be hypnotized by Pegosaurus, after Luna. Unlike Luna, however, Cassandra didn't snore because Evil-Man told her not to.

Debra Jean Rogers (credited as Debbie Rogers in Xianghua in Rockoland) is the person who voices Cassandra while she is in Rockoland.
