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.
