Ultimate Weapons
Each character in the game has an Ultimate Weapon. They are typically the most powerful attacking weapon for each character and they all have 8 Materia slots with NO GROWTH. Having no growth makes them highly undesirable to use for anything other than fights where AP is not cared about, such as the final fight with Sephiroth and the battles against Emerald Weapon and Ruby Weapon (if you don’t intend to level your Materia any further).
Cloud
Cloud’s ultimate weapon is called Ultima Weapon and you can obtain it by defeating Ultimate Weapon (I wish I was joking). Ultimate Weapon (the boss) is first fought in Mideel when you go to rescue Cloud. He can later be found flying around the world in various random locations and finding him involved flying around the world randomly until you happen to run into him.
(Note: Only after you’ve defeated Diamond Weapon. Click here for more information on that part of the game)
The attack power for this weapon is based on Cloud’s HP and his max HP. For example, the most damage is achieved when Cloud is at 9999/9999 and would be significantly less damage if Cloud were at 6702/9999. As a side note, the weapon actually changes color depending on how much HP Cloud has and how much damage its doing. The exact formula for calculating the damage is:
[(3* Power * Current HP )/ Max HP ]+1
Barret
Barret’s ultimate weapon is called Missing Score and can be found when the team returns to Midgar to fight Hojo. Click here for more information on this part of the game. The chest containing Missing Score can only be obtained if Barret is in your party.
The attack power for this weapon is based on the amount of AP the Materia equipped on it has. For example, if you equip level 1 Bolt Materia with 526 AP on it Missing Score will do significantly less damage than if you had attached a MASTERED Bolt Materia. The formula for the weapons damage is:
[Power*(Total AP attached to Weapon /10000 )/16]+1
Tifa
Tifa’s ultimate weapon is called Premium Heart. Premium Weapon can be found by revisiting Midgar using the Key to Sector 5 (click on the link for more information). It’s located in Wall Market in the little hut labeled “Item” that had the malfunctioning gun on your first visit to this area.
The attack power of Premium Heart is based on how full Tifa’s Limit Break bar is. The fuller the bar the more damage she does. It’s also multiplied by whichever Limit Break Level Tifa is on (for more information click here) so make sure to get Tifa’s Limit Breaks leveled up. The formula for calculating damage is:
[Power*(Tifa’s Limit Level * Limit Break Bar Level /16)/16]+1
Aeris
Princess Guard, which is Aeris’ ultimate weapon, can be found in the clock room of the Temple of the Ancients (click here for information). You don’t really get to use it on her unfortunately.
The attack power of this weapon is increased if other characters are KO’d, which I would say makes it useless, but considering you never get to equip it, it’s already a useless item. The formula for calculating damage is:
(x2 for every character that’s KO’d
Red XIII
All you have to do to obtain Red XIII’s ultimate weapon is revisit Cosmo Canyon on disc 3. There’s also a few other items available here. Click here for more information.
The attack power of Limited Moon is based on Red XIII’s MP. The closer his MP is to his maximum MP the better. For example, if Red had 635/635 MP Limited Moon would do more damage than if he had 723/999 MP. The closer his actual MP is to his max the better. The formula for calculating the weapons damage is as follows:
[(3* Power * Current MP )/ Max MP ]+1
Yuffie
You can obtain Yuffie’s ultimate weapon by making a visit to the Sunken Gelnika as soon as it’s accessible. Information on finding it can be found by clicking on the link.
Conformer’s weapon damage is based on what level the enemy you’re fighting is. If you’re fighting a high level enemy the weapon will do more damage. This makes Yuffie’s regular attacks extremely powerful against late-game bosses. The formula for calculating weapon damage is as follows:
( Power * Enemy Level )/16
Cid
Cid’s ultimate weapon is called the Venus Gospel and is the easiest ultimate weapon to obtain. All you have to do is talk to the Old Man found in Rocket Town a few times. This can be done anytime after you’ve gone up in space and returned with (or without) the Huge Materia.
The attack power of the weapon is determined in the same fashion as Red XIII’s, in that it is based of Cid’s MP. The closer Cid’s actual MP is to his maximum MP the more damage it will do. For example, if Cid has 597/597 the weapon will do more damage than if Cid had 701/999 MP. The formula for determining the damage is:
[(3* Power * Current MP )/ Max MP ]+1
Vincent
Death Penalty (Vincent’s ultimate weapon) and Vincent’s Level 4 Limit Break, Chaos, are obtained at the same time. For information on obtaining them both click here (bottom of the page).
The damage this weapon inflicts is based on the number of enemies Vincent has killed throughout the game. It doesn’t matter which weapon he kills them with, the game is keeping track of them all. The more enemies Vincent has killed the more damage that will be inflicted. The formula for calculating the weapons damage is:
[ Power *( Kills /128)/16]+10
Cait Sith
Sith’s ultimate weapon is called HP Shout and this is one of the few ultimate weapons that you cannot get if you missed already. It can be found in the Shinra Building on your second visit (click on the link for more information).
Make your way to Floor 63 and examine the lockers near the back.
The attack power of HP shout is based on the difference between Cait Sith’s current HP and his maximum HP. Therefore, when fully healed up, HP Shout will do the most damage.
[(3* Power * Current HP )/ Max HP ]+1
