Mabel is Kai's twin sister but doesn't mention it much for her own reasons. She cares too much about what people say about her and her reputation. She's a cheerleader and let's it get to her head often. She usually butts heads with Athena and Niko as they're so different but doesn't let it get in the way of their friendships, she always has their backs no matter what. Mabel is your average goody two shoes who doesn't let anything influence her (most of the time). She suffers from an eating disorder caused by her want and need of social acceptance.
