Asia McCarthy is one of the pre-made childdowntownies in The Sims 2: Nightlife. She can be made playable by befriending and aging her up with another child [TS2:FT], and sending her off to college [TS2U]. Asia is a C student in public school at the start of the game, and she is mainly interested in Travel, School, Toys, and Sci-Fi.
Her name is randomized when Downtown is generated. The name "Asia McCarthy" is only referenced in the game files. Like all child downtownies in The Sims 2, Asia's facial structure is seemingly exact to one of the default Maxis face templates in Create a Sim. She has the same facial structure as Andrea Lind, and a similarity likeness to Cara Lewis, a child townie from Bluewater Village.
Like all pre-made child downtownies, Asia has a lifetime want. Her lifetime want is to reach the top of the Militarycareer. Note that while this is usually a sign of a problem in a neighborhood, it is normal for a pre-made downtownie child.
