[[folder:Isabel Evans]]


->'''Played by:''' Katherine Heigl

-> '' "We're just as human as you are..." ''

Isabel Evans is an alien-human hybrid like her brother Max Evans and best friend Michael Guerin. She and Max were found as six-year-old children wandering in the desert by Philip and Diane Evans, who adopted them. Isabel is a very visible, popular girl at school. She hides her kind side beneath a front of haughtiness and cold unfeeling—she is the perfect, unknowable, unobtainable beauty. On the outside, she is the most outgoing of the three hybrids and blends in with the human society with ease. On the inside Isabel is probably the most vulnerable of the three. She so wants to be accepted for her alien side as much as her human side.

* AlphaBitch: For most of season one. It took Isabel a long time to warm up to what she saw as intrusions into her perfect life.
