For better or for worse, Maya is rather hard-headed. She's almost unstoppable, and has pretty strong convictions. But this hardheadedness can also get her into trouble-- in or out of the courtroom.

While she's doing her best to become an adult, Maya still has all the wonder of a kid. This means she can sometimes get herself into uncomfortable situations, simply by touching things she isn't supposed to, being too nosy, or being incredibly... gullible. She hasn't got much of a sarcasm metre.

Self-sacrificing and sweet, Maya Fey puts the feelings of others before herself, especially when it comes to her friends and family. It's a trait she seems to share with her older sister, and one that keeps her strong when the going gets tough. While at times it may seem she hasn't got much conviction for herself, she'll even bravely face a harrowing tragedy for the sake of lightening a close relative's pain.

Physically, Maya is small and looks younger than she is. She can't put up too much of a fight, and has been taken advantage of because of this before; it was very easy to frame her for the deaths of her sister and of her client through physical manipulation.

Like a too-curious Cat, Maya has a habit of sticking her nose into business it shouldn't be in. She isn't much of a gossip, but that doesn't mean she doesn't like sifting through information and figuring things out. To a point, she even feels lonely or left out when Nick keeps things from her, and will often bug him into explaining. This can make her seem immature and sometimes get her in trouble, but it can also aid in investigations... usually unintentionally.

Being the sidekick has a lot of perks; you get to help the hero with almost everything, support them, and get them to buy you burgers. However, you often also have a trope of terrible luck that the hero has to save you from. Maya is accused of murder multiple times, accused of being involved in murders multiple times, kidnapped, targeted, and, well, you get the picture. She's a strong, perky sidekick, but has to deal with the risks of being one nonetheless.

Mystic Maya is a psychic or medium, and all mediums are female. Using E.S.P., she would be-- in theory-- able to communicate with the dead. She used to be a little bad at it, but has been training recently and is able to channel in her last case. However, this requires the presence of spirits to channel, of course. While channelling a spirit, Maya, like any other medium, will find her spirit in a state of complete unconsciousness during which she cannot even dream. While this occurs, the spirit will borrow her body and use it. Two mediums cannot channel the same spirit at the same time, but a more experienced medium can steal a spirit from another medium or can prevent another from channeling by channeling the spirit more quickly.

According to Morgan Fey, Maya's aunt, an experienced psychic can control the spirit they channel. However, the validity of this statement has not been proven and may be challenged by the fact that Maya's mother, Misty Fey, is later involved in an altercation caused by a spirit by whom Misty was possessed. Morgan Fey also purports that there is a Spirit Severing technique; however, because this may have been fabricated by Morgan and Maya never claims to know the technique, it can be assumed she would be unable to use it.

In addition to channeling spirits, mediums can use spiritual energy to charge mystic artefacts such as the magatama, a gem that allows the one who possesses the magatama to see psyche locks. These locks are indicators that a person is hiding something behind a lie or is witholding information as a secret. These locks can only be broken with proper evidence, assuming those who have the locks on them admit to the evidence that is presented.
