Due to living as a coyote in the wilderness for eight years, Malia is, at first, very in touch with her animal side. She is brash, quick to fight and anger, still feral in more ways than one and tends to speak her mind. She displays a fight-or-flight, as well as a survival-of-the-fittest, mentality.
Nevertheless, after seeing life through human eyes, becoming a member of Scott's Pack, and maintaining her relationship with Stiles, Malia demonstrates a quick mind, as well as a close camaraderie, and keeps an open-minded view for those she cares for, accepting Stiles after their relationship crumbles.
Malia struggles with the guilt of her out-of-control shapeshifting that caused the deaths of her adoptive mother Evelyn and little sister. Though she's close to her adoptive dad Henry, and follows, respects the Scott's ideals and morals as her Alpha, Malia fears a killer is all she ever will be, due who her biological parents being Peter Hale and the Desert Wolf.
Malia was 9 years old when she became a victim in a car crash in 2003. Her body was never found. Her family was found three days after their deaths still trapped in the car and seemingly mauled by coyotes.
She is still feral in many ways and considers the world the way a coyote would. She has no concept of friends and does not feel any moral compunction about leaving people behind in order to escape a dangerous situation. She is, however, particularly attached to Stiles and claims that she would never leave him.
Malia is quick to fight and handles pain well. She has difficulty focusing her hearing and other enhanced senses as a human.
