Ivy Young is one of the three main antiheroes of the series. She is the older sister of Adam Young, but usually antagonizes him.
Ivy is the most popular students in Finnegan High, and is portrayed as a stereotypical popular girl: vain, shallow, and often doesn't think things through. Although she is often depicted as slow-witted, Ivy is actually quite intelligent and clever, and has even shown to be this more so than her brother on several occasions. She is also the queen bee of Finnegan High. One of her talents is texting. She seems to have the same personality and brains as her mother. Her main rival is another girl named Madison. She is obsessed with the latest trends in fashion, and would always try to be trendy no matter what.
