Hafu was an extremely skilled Po-Matoran carver. He was widely considered the best of all the artisans in Po-Koro and also a great storyteller. He had a very high opinion of himself and a boastful nature, tending to talk mostly about himself and his achievements.
Hewkii and Hafu were Copper Mask winners and undisputed kolhii champions.
On Metru Nui, Hafu was one of Ahkmou's coworkers. He wore a light brown Rau with silver markings, his torso was light brown, and his feet were light brown.
