Spiked Koopa

Spiked Pirate, also referred to as Pirate Koopa is the first boss in Wario Land: Super Mario Land 3 and a member of the Brown Sugar Pirates. 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 Bros."), 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 Pirate 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.
