6- DR. HILULUK
Dr. Hiluluk was a quack doctor from Drum Island, as well as Tony Tony Chopper’s father figure.
Hiluluk loved Chopper and even ate a poisonous mushroom to encourage Chopper to became a doctor. That showed how strong Hiluluk’s love was, as he took the deadly dish despite his life’s work not yet proven to be completed. Chopper was devastated by his death and decided to become the best doctor he could through the teachings of Kureha. Despite the superior skills of Kureha and other doctors, Chopper would forever memorialize Hiluluk as the “greatest doctor in the world”.
