Zeff is a former pirate who was infamously known as ‘Red-Leg Zeff’. After an incident in which he lost his foot, Zeff opened up his own floating restaurant. He is Sanji’s mentor and taught him all that he knows about cooking. Also, like his young protégé, Zeff not only has a huge respect for food, but also he refuses to damage his hands in battle and fights using his legs. Though he appears to have a very grumpy demeanour and hot temper, Zeff cares a lot about Sanji and the workers at his restaurant.
