Hondo Ohnaka is a Weequay pirate captain introduced in the Star Wars: The Clone Wars animated series in 2008, voiced by Jim Cummings. He kidnaps Count Dooku for ransom in his first appearance, which establishes the whole character: he will sell anyone to anyone, and he will tell you so first.
He recurs across The Clone Wars, Rebels and a run of comics and games, functioning as the setting's designated neutral party — the one recurring figure who is genuinely indifferent to the Republic, the Separatists, the Empire and the Rebellion alike.
