The World Weapons are powerful constructs that exist underneath the world. Created to defeat Jenova, the World Weapons are massive bio-mechanical engines of destruction designed to protect the Planet. Although three World Weapons are known about, five more are rumored to have existed.
Each World Weapon bears an appearance distinct to itself, and a few appear to have elemental attributes. The World Weapons are each tall and massively powerful, with technological advancements far beyond normal means.
