A Falleen male individual was one of the Black Sun crime syndicate's five leaders during the Clone Wars. In 19 BBY, he and the other leaders were killed when the former Sith Lord Maul had his brother Savage Opress execute them for refusing to join the brothers alliance.
The Black Sun leader appeared in the Star Wars: The Clone Wars episode "Eminence," voiced by Dave Filoni, the supervising director of the series.
