Executed by performing a quarter-circle forward motion and pressing punch, Urien fires a large round metallic projectile from his fist that electrocutes foes. The angle the projectile travels at is determined by the punch button pressed; light punch fires it horizontally, medium punch fires it at roughly a 30-degree angle, and heavy punch fires it at roughly a 60-degree angle. The EX Special version hits twice.
The attack has an upgraded form known as Temporal Thunder.
Metallic Sphere has a relatively slow startup, but it can be charged, and can be used to juggle opponents with the proper timing.
