Arthur Slugworth is the main antagonist of the 2023 musical fantasy film Wonka, which serves as a prequel to Roald Dahl's 1964 classic novel Charlie and the Chocolate Factory and a "companion piece" to the 1971 musical fantasy film Willy Wonka & the Chocolate Factory.
He is a renowned candymaker and member of The Chocolate Cartel, alongside his fellow rivals Mr. Fickelgruber and Mr. Prodnose. However, Slugworth grows jealous at the successes the younger Willy Wonka has with his culinary creativity, leading him to conspire alongside his fellow cartel leaders against Wonka to steal his recipes and drive him out of the chocolate making business.
