His name is randomized when Downtown is generated. The name "Chase GilsCarbo" is only referenced in the game files. Despite being a Popularity Sim, he has the lifetime want to reach the top of the Science career. This want makes him compatible, at least in theory, with a Knowledge Sim, though he would have better chemistry with a Romance, Pleasure, or Fortune Sim. Chase is often known to annoy other Sims, due to his lack of nice points.
