The Cabracan is the final boss of Metal Slug Advance. Described only as a weapon which creates earthquakes, it was most likely set up inside of the PF Squad training island by Allen Jr., as part of his revenge plan against the PF Squad. drones while erecting a shield around it's core, which is it's weak spot. After the drones are destroyed, the shield will be gone, so it will fire small shots from it's bottom, after which it will fire a large beam, making the platforms on the arena to fall. It will then fire small ricocheting beams from the core, after which the platforms will reappear and it repeats the cycle.
