Emerald Weapon is an optional superboss in Final Fantasy VII's North American and PAL versions, as well as in its International edition, and one of the toughest of the five Weapons (the others are Ultimate, Diamond, Ruby, and the non-battled Sapphire). Emerald Weapon is released when Sephiroth summons Meteor; Weapons are released when the Planet is under grave threat, to work as its protectors. Emerald Weapon is one of the only two superbosses in the game, along with Ruby Weapon.
Emerald Weapon is located under the ocean, accessible by the Submarine. A battle will ensue after making physical contact, although it is possible to avoid him by piloting the sub at its maximum height. The player will have 20 minutes to complete the battle unless they have the Underwater Materia equipped.
One of the things that makes Emerald a dangerous opponent is its Aire Tam Storm attack — "Aire Tam" is actually "Materia" spelled backwards, and the attack deals damage to each character equal to the amount of Materia equipped on them multiplied by 1,111. As such, having nine Materia or more equipped on a character means certain death. It is possible to manipulate the characters' Materia configuration as to get All Lucky 7s if a character only has two Materia equipped and 9999 HP. All Lucky 7s makes a character go berserk causing massive damage to either Emerald Weapon itself or its eyes.

The still-frozen Emerald Weapon appears as an easter egg in Crisis Core: Final Fantasy VII, buried in Banora Underground. In the northern sections of the first area "Depths of Judgment," Emerald Weapon's shoulders can be seen emerging from a large formation of crystal. The ridges and slots on the shoulders for Emerald's four orbs identify it, but the player is unable to move Zack or the camera in such a way as to see past the crystal. Emerald Weapon lies beyond the map borders, and the player cannot get any closer to it other than this distant view.
