|~ Wamuu to Caesar|
|“||Truth belongs to mighty warriors. Friendship and respect to the braves.||„|
Wamuu served Kars for thousands of years. Always a proud warrior, he fought along him against the Hamon Clan, who were the only ones who had a chance against them. After killing all of the Hamon warriors, Wamuu went to hibernation along his masters Kars and Esidisi. When the woke up centuries later, Wamuu killed the Nazis who were securing them, meeting with Joseph Joestar and his friend Caesar Zeppeli, who were users of Hamon. Wamuu defeated Caesar without much effort, but Joseph caught him off guard with his special clacker, making Wamuu use his special technique, the Divine Sandstorm. Defeated, Joseph tells Wamuu he could get stronger in a month, and Wamuu, who puts heavy pride in battle, accepts his challenge, putting a ring into his heart arteries, so he would not flee. The only way to remove the ring would be by defeating Wamuu and drinking the antidote on his piercing. Wamuu then continues to search for the Red Stone of Aja with Kars and Esidisi, as Joseph and Caesar are submitted to a harsh training. A month later, with Esidisi already beaten by Joseph, he and Caesar locate where Wamuu and Kars were hiding. Caesar goes alone to face Wamuu at a old mansion, and now much stronger than before, wounds Wamuu seriously. However, as Wamuu is a fighting genius, he takes every single opportunity to his advantage, and uses his Divine Sandstorm to defeat Caesar. Before dying, Caesar takes the piercing from Wamuu and leaves it in a bubble of blood for Joseph. Instead of getting it back, Wamuu leaves the ring, in honor to Caesar. Later, he met with Joseph inside the mansion, and Wamuu schedules a fight with Joseph in an old arena. Their last battle would be a chariot race, where both would be running around the arena while taking weapons placed at each turn. After a long and exhaustive battle, Joseph defeats Wamuu, who feels honored to have met him and then vanishing in the wind. Kars grasped Wamuu's dust, remembering old time with Wamuu and whispered: "Wamuu. You were too pure for a warrior."
Wamuu is a very proud, overjoyed, and enthusiastic warrior, who cares only for fighting strong opponents, never wanting to become immortal like his master Kars. His love for battle is only exceeded by his surprisingly moral, virtuous, upstanding, praiseworthy, straightforward, scrupulous, honorable, and almost heroic sense of honor; this is exemplified by his word being his absolute bond, his willingness to honor the dying wishes of particularly courageous and valiant enemies, and most notably in being the only villain in JoJo's Bizarre Adventure who refuses to harm or murder innocent children. It should be noted however, that Wamuu refused to kill innocent children not because of ethics, but because he does not want to waste his power on those whom he views as weak.
