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 for his newly born daughter. During the events of the 'Drugs and the Dominos' arc, Claire Stanfield "purchased" this name to use for himself. Felix seemed to have been one of the most powerful characters in Baccano! despite not initially appearing. According to the president of the Daily Days, he was one of the only people who ever held a chance at killing Claire Stanfield. Claire himself vouches for his prowess, claiming to be stronger than Christopher Shouldered - a "Vampire Homunculus". Felix was hailed as the best assassin in the world before Claire took this position, and even now he is still considered a legend.
