Spiked Koopa

Spiked Koopa Troopa is the first boss in Wario Land: Super Mario Land 3 and a member of the Brown Sugar Pirates. He also appears in a Nintendo Power special, which provided a name for the character. While known as a type of Koopa Troopa in English, his Japanese name derives from Hammer Bros. (｢トゲブロス」 Toge Burosu, translating as "Thorn Bro."), and he appears to wear a helmet, creating some ambiguity as to which group of Koopas he belongs to.

In Wario Land: Super Mario Land 3, Spiked Koopa Troopa resides at the end of the Rice Beach stage and is armed with spiky armor similar to a Koopatrol. In his fight with Wario, he employs a three-pronged attack of striking from land, air, and underground. His shell makes him invulnerable to ground pounds and fire. However, he can be rammed into, exposing his soft belly. After three hits to his vulnerable underside, he is defeated.
