 In early appearances, the character was a Yellow Peril ethnic stereotype, complete with caricaturish Asian facial features and dialogue written in a phoneticized Chinese accent.His name is an obvious play on the American Chinese restaurant omelette dish egg fu yung.Certain 21st-century updates, such as changing his name to "Chang Tzu" and affiliating him with DC Comics' Chinese superhero team the Great Ten, maintain his Asian ethnicity while striving to de-emphasize problematic aspects of his historically racialized characterization.
