Wamuu

The Pillar Men are from a race of ancient, humanoid, super-human beings. These beings are now nearly extinct, but used to live hundreds of thousand of years ago in the American continent. They are highly intelligent, extremely strong, and able to manipulate their bodies to a very extreme degree; however, they are vulnerable to the rays of the Sun and to the Ripple. This race was wiped out by Kars and Esidisi, leaving two babies to be spared, Wamuu and Santana. Wamuu is one of the last four Pillar men alive along with his masters Kars and Esidisi, and fellow Santana. He was raised and trained by Kars and Esidisi, Wamuu grew to have a love for battling. He helps Kars in his pursuit of the Red Stone of Aja to become the Ultimate Lifeforms, however, Wamuu does not care about the evolution bullshit and only helps Kars because he owes him for being raised.

Wamuu's most notable traits are his love of battle and his sense of honor, such that he stops himself from finishing off a defenseless Joseph Joestar on the mere possibility that he can wash away an earlier humiliation inflicted by Joseph when he'll beat him as soon as he becomes a fine and powerful Ripple warrior. Wamuu usually looks down on all the humans he comes across to, but he will come to respect them should they have the following two requirements: firstly that the fighters take combat seriously, and secondly that they are strong fighters. Thus Wamuu sneered at Caesar Zeppeli when he declared that he fought for his friend Mark, yet honored Caesar's last efforts to steal the antidote for Joseph and left it for Joseph out of respect for the strength Caesar demonstrated. Because of his way of life centered around fighting, Wamuu tends to ignore non-combatants, for instance telling Joseph to leave during their first meeting, mistaking the young man for a harmless goof. Wamuu is also one of the few antagonists in the JoJo franchise who cannot bring himself to harm or murder children, a moral compunction that his master Kars does not share. However, anyone earning his attention becomes a target for his challenges. Wamuu is as severe toward himself as he is toward anyone else save his masters. For instance, he once let Joseph beat him as punishment for letting his guard down and strongly disliked that Joseph expressed pity on him. On the other hand, Wamuu has a high opinion of himself, as he regularly deems certain individuals "worthy" or "unworthy" of fighting him. Wamuu also opted to kill the helpless Speedwagon and Caesar who saw his humiliation before being distracted. As a testament to his commitment and strength of character, Wamuu has developed himself an extreme mental switch designed to help him focus if he ever enters a state of shock or panics during combat. Thus, he will gouge his eyes and rely on his wind-sensing horn as a means of seeing. Kars even went further and said that after activating his mental switch, Wamuu no longer has any psychological weaknesses. When it comes to fighting, Wamuu is irritated that a fighter might try to flee or surrender, but he considers using tactics such as ambushes or feints to beat one's opponent acceptable. The only thing that rivals his sense of honor is his fidelity toward his masters Kars and Esidisi, who raised him since he was a baby. He respects both highly, yet holds no illusion that neither of them has the same sense of honor and can objectively assert their strengths and weaknesses. During his battle with Caesar, he noted that Kars would have an even harder time fighting Caesar than him. Wamuu occasionally requests that his masters change their plans to suit his love of fights, which they allow easily since they have raised Wamuu as their finest warrior but also can refuse. Either way, Wamuu will obey their command. Wamuu has a weird personality quirk, where he reflexively attacks anyone who steps on his shadow, even if it was one of his masters (Kars and Esidisi). Somehow, Wamuu is able to tell when someone is stepping on his shadow, even if he wasn't looking at their direction.

He is loyal and respectful towards his Masters, Kars and Esidisi, who are the two pillarmen who had raised him. He has respect towards Joseph and actually respects him for being a cunning and strategic fighter. He respects Caesar as well for being an worthy warrior and for giving him an amazing battle.

Wamuu appears as an immense being; powerfully built and tall. Many of his more detailed drawings have his veins bulging from his extremities. His face is particularly chiseled and square with high cheekbones.

Wamuu has short, standing light hair and prominent eyebrows. On his face is a tattoo of a thick square outline. It crosses his face just under the bridge of his nose, upwards through the middle of his left eye and ending above his right eyebrow. In one particular close-up of his face, the tattoo has the word "POWER" written several times in it, as well as the word "ALPHABET". As a Pillar Man, he has a singular, relatively large drill-like horn above his forehead that he can retract.

In all of his appearances, Wamuu wears large earrings and a metallic head adornment similar to a crown that opens at the front whenever he summons out his horn. Up until his defeat of Caesar, he has a small ring on the left side of his lip containing the antidote for his Wedding Ring. Overall he's the biggest and most muscular out of the Pillar men.
