Shabaroller

Shabaroller (シャボローラー) is an enemy in Mega Man Zero 2 that is in a way similar to the Totem Cannon. It has two sections, a top and bottom section. Each section has spikes on one side and a shield on the other. The Shabaroller spins around, alternating the positions of the shields and spikes to attack and defend. It is found in the Desert Wilderness, the first stage of the game.

Trivia

 * Its name may be derived from cactus (サボテン saboten, also written as シャボテン shaboten) and roller.
