The Former Felix Walken

Felix Walken (フェリックス・ウォーケン Ferikkusu Wōken) (former name) is a retired assassin who left the game to care his newly born daughter. During the events of the Drugs & Dominos arc Claire Stanfield "Purchased" his name to use himself. Felix seemed to have been one of the most powerful characters in Baccano despite never actually appearing; according to the president of the Daily Days Felix was one of the only people who ever had a chance at killing Claire Stanfield. Claire himself vouces for his prowess as being stronger than Christopher Shouldered, a "Vampire Homunculus" and finally Felix was hailed as the best assassin in the world before Vino took that possission.
