Engine Stopper Base
Blade Base: Engine Stopper Base
Must be used with Gyro Engine Gear.
Despite its name, the actual Engine Stop gimmick is part of Gyro Engine Gear, Engine Stopper Base is simply a plastic shell which houses Gyro Engine Gear to prevent damage etc.
Has two sloped protrusions which have relatively minor interaction with opponents as they tilt due to the generally free spinning nature of the part in its primary mode of usage, though they can provide some destabilisation.
There is a minor mold variation where some versions lack the small line near the ripcord on one side.
