Wamuu is a Pillar Man and a major antagonist in JoJo's Bizarre Adventure Part II: Battle Tendency. He, alongside Esidisi and Kars, are seeking a super variant of the Red Stone of Aja to unlock true perfection. After awakening over a two-millennia long sleep, he is confronted by Joseph Joestar and Caesar Anthonio Zeppeli. Finding an opponent who can truly harm him in Joseph, he grants the Joestar a reprieve to hone his Hamon skills within a month to face him as an equal. As added incentive to ensure the human will not run off, Wamuu plants a poisonous ring inside Joseph's heart which only he has the antidote to.
