Mean girl could refer to any number of characters. One such character, played by actress KylieRae Condon, appeared in the "Falling" episode of Supergirl in 2016. This obnoxious red-haired girl was a bully with a group of friends who used to pick fun of a younger girl named Laura for wearing a Supergirl costume to school. The real Supergirl overheard this incident while flying and came down and used her x-ray vision to peak into the girl's backpack and saw her name written on some of her school supplies. Supergirl greeted Laura, addressing her by name, and acted as if they were pals. The older mean girls were suitably impressed and left Laura alone.
