Bild Quates (ビルド・クェーツ, Birudo Kuētsu) is Szilard Quates' descendant in the 2002 storyline. He makes an appearance in the fifth Baccano! volume, 2001: The Children of Bottle. Bild is a very dutiful man who is determined to stop Szilard's research and end his bloodline with himself. He is very opposite to his ancestor in terms of personality and morality, despite bearing a striking resemblance to Szilard. It is unknown whether Bild is a descendant of a child that Szilard sired or one of his homunculi.
