Wamuu is introduced as a servant to both Esidisi and Kars. He is a very strong and honorable warrior who possess the power of the wind, and also reflexively attacks anyone who steps on his shadow. If he goes blind, he can grow a horn on his forehead and sense sound waves with it. He can also draw air into his body and blast it through the tip of the horn, creating a highly-destructive "wind scalpel". He is also extremely honorable, stopping himself from defeating a defenseless Joseph Joestar when he said that with a month to train he could beat Wham. Later on, he engaged in battle with Caesar Anthonio Zeppeli and killed him, but not before he managed to rip off Wamuu's lip piercing containing the poison within Joseph. In another display of honor, Wamuu allowed the antidote to stay where Joseph could get it out of respect for Caesar's valiant effort. Later challenging Wamuu to battle to avenge Caesar, they engaged in a deadly Roman chariot race, with Wamuu initially getting the upper hand. After Joseph managed to counter Wamuu's wind scalpel, he was left as nothing more than a head with the Ripple energy slowly killing him. After Joseph gave Wamuu some of his own blood to ease his pain, he used the last of is strength to destroy a group of vampires that attempted to kill Joseph. Wamuu then vanished in a gust of wind, with Joseph giving an unconscious salute to him. He is named after the 80s duo featuring George Michael, Wham!. (Source: Wikipedia)
