Being a cop in a big city, Elisa can be tough when the situation calls for it. When she first meets the gargoyles, she is quite skeptic about them, but becomes fast friends. She cares for the well-being of them, going far as to keep tabs on Xanatos when the gargoyles or her family are involved. Over the course of the series, she develops romantic feelings for Goliath, who also harbors feelings for her as well. However, they both do not admit how they feel about each other, as they have doubts that a relationship could work between them because of their different species. Eventually, they are able to get past this once they realize that they care for each other too deeply and finally confess their feelings in the three-part Season 2 finale, Hunter's Moon. They become a couple soon after this and remain together during the third and finale season of the show.
Elisa has dark blue hair, brown eyes, and copper skin similar in appearance to Pocahontas. Her normal outfit consists of black boots, light blue jeans, a black shirt, and a red leather jacket. During the Avalon World Tour, she dons other outfits while visiting the different locations.

She gains another foot in height, revealing her waist, along with a human skin-colored tail. She loses her shoes and gains double-jointed bare feet. She also gains extra bone structure on her forehead with small horns and bigger eyes.
