Ogrenix

Ogrenix (オーガニクス Ōganikusu), also known as Organics, The Ogre, or Organyx, is a recurring weapon in the series. It is often a mid-ranked weapon with mediocre power, and usually boosts some type of special ability.

Final Fantasy VI
Organyx, originally called Ogre Nix, is a high-ranked weapon only Terra, Edgar, Locke, and Celes can use. It has an Attack of 182 and consumes 10 MP each hit for an automatic critical hit, but has a chance of breaking after each use. It can be acquired by betting the Flametongue, Icebrand, Thunder Blade, or Zantetsuken in the Dragon's Neck Coliseum. It can also be Metamorphed from the enemies Gigantos, Glasya Labolas, Hill Gigas, and Muud Suud.

Final Fantasy VII
Organics is a mid-ranked weapon for Cloud, and can be bought at Icicle Inn for 12,000 gil. It provides +63 Attack, 103% Attack%, +15 Magic, and has six Materia slots, with four being linked.

Final Fantasy IX
The Ogre is a mid-ranked weapon for Zidane only obtained by synthesising two Mage Mashers. It provides +24 Attack, has innate Darkness status, and teaches the ability Soul Blade. It appears like two Mage Mashers combined. It costs 700 gil to synth at Lindblum, Treno, Alexandria and Black Mage Village.

Final Fantasy X
The Ogre is a claw for Rikku, and possesses any three Magic Plus % abilities. Auron has a similar weapon called the Ogre Blade, which also uses three Magic Plus % abilities.

Final Fantasy XI
Unlike in other games, the Organics in Final Fantasy XI is a high-level knight sword, which increases Strength, Attack, and critical hit rate at a cost of reducing maximum HP. It is dropped from the Achamoth.

Final Fantasy XIII
The Organyx is a model of a gun-sword for Lightning. It has the most growth in Strength and Magic value among her weapons, reaching 750STR and 750MAG if upgraded to the maximum level in its final form. As a balancing factor, Organyx also has the trait Leadenstrike, which decreases ATB speed by 70%. Leadenstrike's effect is decreased as Organyx is transmuted into its second form, Apocalypse. The Organyx can be bought at Retail Network at Gilgamesh Inc for 280,000 gil.

Final Fantasy Tactics A2: Grimoire of the Rift
Ogrenix is a mid-level Greatsword that teaches the abilities Sanctify, Full Assault, and Sword of Light. It provides +47 Attack.

Dissidia Final Fantasy
The Ogrenix is a level 50 greatsword that increases physical damage by 10% and boosts +37 Attack. It can be traded for at the shop for 16,280 gil, a Zweihander, a Gigas Bone and a Transmogridust.

Zidane also uses The Ogre from Final Fantasy IX by fusing both of his Mage Mashers when executing some of his Brave and HP Attacks and most notably his EX Burst Reverse Gaia.

Trivia

 * The Final Fantasy VII version of the Organics resembles the Longswords used by Tidus in Final Fantasy X.
