Cheryl Miller is a hidden downtownie in The Sims 2: Nightlife. She can't be made playable without cheats. Unlike other downtownies, Cheryl does not appear in-game because she is not placed in any of the SimBins when viewing SimPE. However, with SimPE, it is possible to add her to one. Cheryl has a similarity likeness to an un-hidden downtownie Christa Mazza. Cheryl has no turn ons and offs, nor does she have any interests or skill points.
As a hidden downtownie, she does not have a randomized name. Caryl Gray also has this case. According to Cheryl's SimDNA in SimPE, her hair was blonde before it turned grey. Like most downtownies in The Sims 2, she has a customized facial structure. Cheryl's face is mostly a customized version of the 15th Maxis face template in Create a Sim.
