Stairface Ogre

Stairface Ogres are enormous Whomp-like enemy creatures wielding a stamp-like mallet found predominantly in Bowser's Kingdom within Super Mario Odyssey. They are called the locals of Bowser's Kingdom within the in-game brochure. Their primary means of attack is to smash their mallet down where Mario is standing, which allows Mario to climb up their mallets. Before swinging down their mallets, they telegraph where they are about to attack Mario with a large glowing red square in front of them. Stairface Ogres can be defeated by performing a Ground Pound on top of their head or by poking the glowing hole on their forehead while controlling a Pokio. Once a Stairface Ogre is defeated, it explodes and makes a wailing sound.

Their faces bear a striking resemblance to that of a Thwomp, and they seem to be based off of the mythological, which is sometimes seen as a Japanese counterpart to the ogre. Additionally, their manner of attack and defeat is similar to that of a Whomp as well. The “Stairface” part of their name is a portmanteau of “staircase” and “face”.

The mission "Infiltrate Bowser's Castle!" in Bowser's Kingdom specifically requires Mario to defeat a Stairface Ogre to progress. Additionally, Stairface Ogres can be used to break blocks, which is useful for revealing items (if any) inside the blocks.

After Bowser is defeated in the Moon Kingdom and the Moon Rock in the Metro Kingdom is activated, Stairface Ogres can be found in a dark secret area known as Pitchblack Island accessible via Moon Pipe in New Donk City.

Terrifying Gatekeepers
''Don't run afoul of the Stairface Ogres that guard this kingdom. When they spot an intruder, they bring their huge mallets down, no questions asked. On the other hand, you have to admire their tenacity and work ethic. The scars on their faces show that they don't give up easily.''
