Xerxes wears a nearly half-unbuttoned, spotted white shirt, and blue jeans. She also wears several items of jewelry. Her right ear, nose, and right eyebrow are pierced. She also has been seen wearing a Bluetooth headset on her left ear. Despite attempting to masquerade as a man, she seems to have very "worked on" eyebrows.
Xerxes has a compromise-type personality, originally willing to reason with the girls who were preventing them from taking over Les Bos. She also seems to have a lust for power, even going as far as masquerading as a man so she could become the leader of South Park's Persian club.
In "D-Yikes!", she is seen scissoring with Mrs. Garrison, with this, we can presume that they may have had a short relationship (Although, it could've just been a one-night stand). Mrs. Garrison has since "changed back" into a man, and since Xerxes is a lesbian, we can assume that their relationship is over.
- Her name, as well as her appearance, is a parody of how the movie 300 portrayed the legendary Persian king, Xerxes.
- In reality, Xerxes was a male king, who ruled Persia from 485 to 465 BC.
- Despite being female, her voice is extremely deep.
