Negata was the corrupt founder and CEO of the eponymous Negata Industries. He is the final antagonist of The Red Jacket Series, appearing in Farewell My Beloved Lupin.
At first glance, Negata was a mere industrial businessman who specialized in military contracts. Beneath the surface however, Negata's greed possessed him into resorting to Black Market arms dealing. Personality-wise, Negata was nothing but greedy, constantly seeking to increase his personal wealth. With Maki Oyamada under his employ, Negata found a veritable treasure trove of technology at his disposal, just waiting to be profited off of. His first act was to convert Oyamada's inventions into weapons and sell them to the Japanese Military, signing on as their principal supplier.
