Alex, the middle and only female Russo child on "Wizards of Waverly Place," is perhaps the most sarcastic character ever to grace the Disney Channel and it's hard not to love her. Although she typically winds up in trouble -- either for her sharp tongue or her constant schemes -- it takes a lot of brain power to come up with the words and devious plans she does. While her older brother/arch nemesis Justin excels in both wizard and high school, it's Alex (Selena Gomez) who has the street smarts. As she says in one episode, "I am too book smart! Sure, I don't read books, but I hollow them out and hide things in them." Maybe she even has enough smarts to win the family wizard competition after four seasons of ups and downs.
