Hafu

(Note: Although Hafu is canonically male, I have left the role open to both male and female actors, since female actors, at least in my personal opinion, can do very convincing "young boy" voices, and I didn't want any prospective female actors to be put off by the character's canonical gender.)

Hafu (pronounced HAH-foo) is a Po-Matoran carver and Hewkii’s best friend. He is extremely devoted to his work, and has a somewhat inflated ego, considering his carving skills to be unmatched. He usually spends time away from other Po-Matoran, working on his carvings. However, despite his arrogance and tendency to show off, Hafu is dedicated to his friends, and is both brave and strong.
