"Let's get into the popularity!" - Mercury
Mercury is a blonde and kinda smug girl with her heads into popular guys in the high school, mostly into Liam. Despite that, she still does have a care into those she, with some of the other kids, usually call freaks, including to Mars and Jupiter a little. Mercury has a bipolar personality and can cause her to violently change the way how she feels like going from happy to a big anger.
She's shown to have a little of parents issue, possibly because she recently turned into a teenager, but she mostly hides it in secret. She might be that a little smug, but she is also a good friend after all.
