Sister Ray

The Sister Ray is the codename for an energy cannon owned and operated by Shinra in Final Fantasy VII.

The cannon fired Mako-infused artillery shells and was capable of great destruction, successfully destroying both the Sapphire WEAPONs and Diamond WEAPONs and breaking the energy barrier surrounding the North Crater (though the latter accomplishments were down to the cannon using the Midgar Mako reactors to form some kind of particle beam instead of artillery shells). The Sister Ray was originally mounted in the harbor of Junon, but would later be moved to Midgar.

In Final Fantasy VII: Advent Children, the Sister Ray still stood, though it had decayed and crumbled after two years of neglect and the damaging attentions of Meteor.
