Bilt Quates (ビルト・クェーツ, Biruto Kuētsu) is Szilard Quates' descendant in the 2002 storyline. He makes an appearance in the fifth Baccano! volume, 2001 The Children of Bottle. Bilt is a dutiful man who is determined to stop Szilard's research and end his bloodline with himself. He contrasts his ancestor in terms of personality and morality, but is strikingly similar to him in terms of appearance.
