Ann is based on Hunter S Thompson and Anne Shirley. Ann is the gruff teacher of stealth and security who is seen as the definition of a super spy, paranoid, perceptive, harsh, effective and heavily principled. She wears a blue cap, sunglasses, blue button down with rolled up sleeves and is almost always shown smoking a cigarette to the dismay of her peers. She has a “Hell’s Grimm” tattoo on her. She also has an insane love of firearms having a gun almost everywhere on her body. She dresses rather masculine with a security guard vibe to her look and is almost always hunched over. She starts almost all her classes by telling her students to pop a squat. She holds the idea that “three people can keep a secret if one is buried six feet under and the other lobotomized”. She’s actually a good teacher otherwise. She’s the kind of person who may or may not know too much and is aware of almost all going ons around her. She alludes to the fact that someone may be trying to break into Beacon to bring it down but most dismiss her as crazy and neurotic.  

Gruff, paranoid. Imagine a female version of Colonel Hunter Gathers. Easy on the gruff and more along the lines of a huskiness.
