The Vortex is a medium/large-sized treaded vehicle used by the Rebel Army. It first made its debut in Metal Slug Attack as part of the Blaze Brigade's latest equipment, but its name was not revealed until "Task Force 12th".
|Grazia's Vortex: A customized version of the Vortex operated by Grazia. Just like her "Blaze Tank", her Vortex travels underground directly below her and partially emerges from the ground whenever Grazia calls for it. Grazia's Vortex produces a large fiery ball that bursts out flame dragon heads.|
|Loretta's Vortex: The above-ground Vortex, operated by Loretta at the top. Per Blaze Brigade standards, it has red-gray metallic plating and utilizes flame induction particles to scorch enemies.|
|Frozen Vortex: An unmanned variant of Loretta's Vortex from the "Frozen Brigade", possessing icy blue metallic plating. It is designed to operate in cold battlefields, utilizing the cold air and turning it into dangerous energy to freeze enemies and produce large walls of ice.|
