Lou Bismarck is the elderly patriarch of the Bismarck family, a powerful criminal syndicate operating across the galaxy. He is driven by an intense desire for immortality and will stop at nothing to achieve it, including running dictatorships, smuggling arms, and plotting to conquer the entire galaxy. His ruthlessness is exemplified by his willingness to deploy a devastating virus that threatens to exterminate all life in the cosmos. As the head of the Bismarck family, he commands a vast criminal empire and orchestrates numerous schemes to obtain power and resources, often at the expense of innocent lives. Lou is the primary antagonist of the story, with his family's actions directly motivating the protagonist's quest for revenge. He is the patriarch of several key antagonists, including Cross Bismarck and Jera Bismarck, and his influence shapes the conflict across the series. Lou Bismarck relies on his strategic mind, vast resources, and deadly technologies rather than any personal combat abilities, making him a cold and calculating adversary whose ambitions extend far beyond simple profit.
