Portrayed by

Meredith Bishop

Annie Mack (sometimes just called Anne) is Alex Mack's older sister. With incredible talents in science and chemistry, Annie is often the more favored of the two Mack sisters by their parents.

Upon learning of her sister's powers, Annie begins to test Alex as part of her personal science project (in hopes of winning a Nobel Prize). Though at first it seems that Annie only cares about Alex for the sake of her scientific research, she does indeed show genuine feelings for Alex's well-being.
