Steam Hammer is a large enemy in the Kirby series, debuting in Kirby: Planet Robobot. It cannot be inhaled.

Physical Appearance

Steam Hammer is a giant, steam-powered mallet connected horizontally to a metal pillar. The mallet itself has a copper and brass exterior with exhaust vents to release steam from. The front of the mallet has a pale green face a toothy grin and artificial red eyes.

Steam Hammer's pillar is also made out of copper and brass. It is the source of the enemy's steam, with a pressure gauge on the front and three steam-releasing pistons on the top.


Kirby: Planet Robobot

Steam Hammer first appears in Stage 3 of Patched Plains. It swings around its pillar endlessly, passing between planes as it does so. If Kirby is struck by the enemy, he is either launched directly into the screen or into the distance, depending on where he was hit in the mallet's swing arc. Both cause Kirby to drop his Copy Ability.

Steam Hammer is immune to all attacks except those used by Robobot Armor (or, in Meta Knightmare Returns, Galaxia). If one such attack hits the enemy, the mallet explodes, dropping a Green Point Star. The arm on the pillar immediately stops swinging upon the destruction of its head.
