Alyx Vance

The Alyx Vance, the heroine on the side of Gordon Freeman!

Alyx is the daughter of Dr. Eli Vance. Her mother, Azian Vance, who is of Asian descent, can be seen in a family photograph appearing in the games but died during the Black Mesa incident (the event depicted in the first Half-Life game). Alyx was only a child when Gordon Freeman was employed at Black Mesa, but Freeman's stasis between the events of Half-Life and Half-Life 2 has erased most of the age gap between the two characters.
