A robo-pirate that spins, lashing out with its arms.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Shisaku-gata Spanner[1] (試作型スパナ[2] Shisaku-gata supana?, lit. "Prototype Model Spanner") is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, pirate-based Badnik mode serving Dr. Eggman and Eggman Nega.


The Shisaku-gata Spanners have a gray, skeletal appearance with skull-like heads, yellow eyes, large jaws, mechanical-looking gray arms with yellow pincer-like hands, gray torsos with tall red midsections, and no legs connecting their bodies to their yellow feet.


In Sonic Rush Adventure, the Shisaku-gata Spanners appear as enmies. They are encountered in Machine Labyrinth and Hidden Island 10.

In gameplay, Shisaku-gata Spanners patrol their designated areas by moving around. When the playable character gets near them however, they will attack by spinning their torsos around vigorously with their arms outstreched for a few moments. Regardless, they can be take out in one hit with any attack in the player's arsenal.

Powers and abilities

The Shisaku-gata Spanners possess articulated torsos that allow them to spin their upper bodies around at high speed.


Each Shisaku-gata Spanner carries a spanner in its right hand that it uses as a melee weapon.
