hr-h
A giant mecha appearing in Kirby 64 as a boss on Shiver Star, attacking with missiles, arm-swipes, and lasers. While most bosses in Kirby 64 have two phases, HR-H's second phase is treated as a separate boss called HR-E, who attacks with carpet bombs, rockets, and pincers.
Any connections it or HR-D3 may have to the Haltmann Works Company are for now left ambiguous.
