Also, her supreme fighting skills come with a serious drawback: She can't hold back when fighting, so even a simple brawl causes her to overexert herself, which results in her passing out once the fight is over.
Genius Ditz: Zolov, Gaia's chess partner from the early books, suffered from Alzheimer's Disease to the point where he couldn't even remember that Gaia's name wasn't "Cindy." He also royally schooled her at chess every time they played, which is no small feat, considering that Gaia is the equivalent of an internationally ranked Grand Master.
