Alexandria Anastasia "Alex" Dunphy is the second daughter of Claire and Phil Dunphy. She is evidently the most clever and intelligent of the three siblings. Also the middle child to a shallow big sister and a goofy younger brother, she enjoys messing with them when they are rude to her, which is fairly often, taking advantage of their naivety and inferior intellect by fooling them into believing unrealistic things. At one time she had convinced Haley and Luke that they could charge electronics by rubbing the battery on her head and holding it in his mouth. As much as she enjoys torturing her brother and sister, she always seems to have their backs, as in "Undeck the Halls" when she confesses to smoking, even though she didn't do anything, to bring back Christmas for them or in "Games People Play", when Alex says she would have tutored Luke if she had known he was failing Pre-Algebra.
