Ava is considered the toughest cookie of them all. Though she looks like an innocent, shy girl outside, she is actually a daring lady inside. Ava has a fiery temper, and dislikes to be approached by men. This often lead herself into trouble with Max. She can also quickly swap personality, from a kind-hearted girl to a sharp-mouthed lady. Her beautiful face attracts men, most of all Max, who has strong feelings for her.

She is the best hand-to-hand fighter at the team, even surpassing the chief. However, she is proved to be a failure when aiming with a gun, as she always misses her target.

Case Appearances

She will appear in every case where forensic analysis is needed.


  • She is very tough, as she was once crowned 'The Queen of Fighting' in college for beating ten black-belt karate fighters in five minutes.
  • She has a habit of punching those who inappropriately flirts or approaches her. This explains why Max sometimes is seen with a bruise in their face.
  • She once dared the chief to a martial arts match, and ends up with her suspended for three days.
  • Sahir is the only person known to have actually beaten her in an argument.
  • Although Ricky admires her beauty, he doesn't dare flirt with her, and let Max become the "experimental rabbit".
  • She loves rabbits, going as far as keeping one in her lab named Mr. Bunny.
