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, but is strikingly similar to him in terms of appearance. It is unknown whether Bild is a descendant of a child that Szilard sired or one of his homunculi.
