Zarale

From Memory Alpha, the free Star Trek reference.

Gul Zarale was an infamous leader among the Cardassian military stationed on Bajor during the occupation.

Li Nalas was remembered and made a hero for slaying Zarale in combat. However, Li had done nothing of the sort; he shot Zarale in cold blood while Zarale was in his underwear. Li didn't want to be a hero for doing such a thing. (DS9: "The Circle")
