Zess is a tall and incredibly muscular woman, with an exceptionally curvy body. She is blind in one eye, and wears an eyepatch over it. Zess likes to show off her strength in various ways, and is rather boastful about it. Despite this, she is generally friendly and kind. Zess is quite self-aware and often likes to make jokes comparing herself to the character Baiken from the Guilty Gear videogames, or Asuka from the anime Neon Genesis Evangelion.
