Jetpack-wearing robo-pirate that gets in the way.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Shisaku-gata Jet[1] (試作型ジェット[2] Shisaku-gata jetto?, lit. "Prototype Model Jet") is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, pirate-based Badnik serving Dr. Eggman and Eggman Nega.


The Shisaku-gata Jets have a gray, skeletal appearance with skull-like heads, yellow eyes, large jaws, mechanical-looking gray arms with three fingers on each hand, gray torsos with tall red midsections, and no legs connecting their bodies to their yellow feet. Attached to their backs are large and gray steam-powered jet packs with round noses, yellow cables, measuring needles, and handheld controls on the sides.


In Sonic Rush Adventure, the Shisaku-gata Jets appear as enemies. They are encountered in Machine Labyrinth, Hidden Island 9, and Hidden Island 10.

In gameplay, the Shisaku-gata Jets hover in the air with their jet-packs, occasionally moving up and down. They can sometimes be encountered while the player is using a Hang Glider to glide throughout the Acts, serving as obstacles that the player typically has to avoid.

Powers and abilities

Thanks to their jet packs, the Shisaku-gata Jet are capable of flight.
