Susannah Laura "Susan" Test is a fictional character from the American animated series Johnny Test.
She and her older twin sister, Mary are both super-geniuses and one of Johnny Test's older sisters who use their little brother like a lab rat for many of their experiments and inventions in their home laboratory, most of which he doesn't mind at all, unless he's bribed by them for one that he doesn't want to do.
Both Susan and Mary attend school at the Porkbelly Institute of Technology (aka Porkbelly Tech) and harbor a crush on their next-door-neighbor, Gil Nexdor, who doesn't even know they exist.
