WESAYSO Corporation

The WESAYSO Corporation was an apparently all-consuming, all-powerful mega-corporation that effectively ruled the fictional world of which the Dinosaurs existed: a parody of consumerism at its worst the WESAYSO Corporation is arguably the main antagonist of the entire series, becoming more destructive as the show progresses until its ultimate involvement in what would become the extinction of the dinosaurs in the series finale.

The WESAYSO Corporation ran everything and claimed to know everything, though in reality they basically made the rules and by extension only knew everything because they made things up - covering up anything they didn't approve of or didn't understand (often quite badly, yet most of the population never questioned them).
