Harimen (ハリメン, meaning "needle face") are enemies in the Game Boy Advance game Wario Land 4. They appear as yellow heads with red feet that wear pink spiked shells, resembling Spinies. Their shell hurts Wario on contact and is immune to his ground pound and ram attacks. There is also no way to grab them. Their weak point is their unprotected underside. The most common way to defeat the Harimen is by perfoming a ground pound around an area where they are seen, causing them to flip over and to be stunned for a few seconds. Another ground pound directly on their underside will defeat them, rewarding Wario with a Silver Coin. Harimen will flip back over when Wario touches their underside without a ground pound. When another enemy is thrown at them, they are defeated immediately. They can also be caused to flip over by pushing them against a wall, which can be safely done when Wario is invincible, for example as Flaming Wario. As most enemies, Harimen are also defeated when Wario simply touches them during a certain transformation, such as Zombie Wario or Fat Wario.
A sub-species known as Harimenzetto exists as well, who have a black shell and are more difficult to defeat.
