The Super Grenade is a special weapon introduced in Metal Slug X. It is represented by the icon .
As powerful as the regular grenade while having increased range, the Super Grenade can quickly demolish targets in its way, although the smoothbore tip will not enable it to pierce through thick armor. The grenade travels fast, and creates a massive explosion capable of destroying anything over the target. However, to compensate for the massive damage it does, it has low amounts of ammo and can only fire two grenades at a time. When fat, the Super Grenade turns bigger.
In the PlayStation port of Metal Slug X, the Super Devil fires small Super Grenades rather than Slug Cannons. Since the Super Devil wields a pistol, they can fire multiple rounds at once.
