Wamuu

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 highlydestructive 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. He is named after the 80s duo featuring George Michael Wham. Source: Wikipedia
