Skull Magnum

The Skull Magnum (スカルマグナム) is Kamen Rider Skull's firearm and only weapon. When the Skull Memory is set in the Skull Magnum's Maximum Slot (マキシマムスロット), and then the gun is set in Maximum Mode, it initiates the Skull Memory's Maximum Drive: a series of powerful energy bursts called the Skull Punisher (スカルパニッシャー). Skull typically uses the Magnum in Maximum Mode, but in Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core, Skull Crystal wields the weapon in its Normal Mode.
