Jack is a serial killer hailing from late 19th century Britain and is a very important figure in the history of London, being considered "Humanity's Most Infamous Serial Killer." Normally, Jack has the disposition of a typical British gentleman, accentuated by his sophisticated diction and actions. He is also a big fan of Shakespeare, usually quoting some of his poems while talking to others. Jack is a cold-blooded monster at heart as he gleefully murders people simply to bask in their fear.
