Ultimate weapons are, of course the character's last and best weapons. They do a large amount of damage, but have one downside. They normally have no growth for materia, so usually only MASTER materia is recommended for an ultimate weapon.
CLOUD
Ultimate Weapon
This is obtained by killing the Ultimate weapon
that is flying around the lake by Junon. The weapon is not that hard to
defeat and should not take too much effort.
The weapon gets its strength from Cloud's HP. The higher the HP, the more
damage it will do.
BARRET
Missing Score
This can be achieved on the steps that lead
up to the sister ray. Before you fight Hojo. There is a save point right
before the steps. This is useful because Barret is required in your party
in order to get the treasure chest on the steps. Just use the PHS and put
him in your party if he isn't already
This gets stronger the more AP a materia has when it is equipped on the
weapon. So if you put master materia on this, it will cause a LARGE amount
of damage.
TIFA
Premium Heart
This weapon takes a bit of time to get. You
must first get the "Key to Sector 5 " key item. This is found
in the Bone Village. Just send out for an excavation party for "normal
treasure". You should get the key. Now, go back to Midgar and go through
the doors. Make your way to Wall Market and go to the vending machine that
was broken earlier. (The one with the machine gun) It should be fixed now
and you should get the Premium Heart from it. After that it will break
down again forever.
This gets its strength as Tifa scores Yeah's on her limit break slots.
the more Yeah's she hits, the more damage it will accumulate. But as it
gets to 9999, it will drop down to lower digits. This is was not taken
from the Faq by K. Megura. Which says that the more Misses you score, the
more it powers up
AERIS
Princess Guard
This is found in the temple of the Ancients.
It is found in the clock room at the end of the 4th digit.
This supposedly powers up as she heals her allies. The more she heals the
more damage it deals
RED XIII
Limited Moon
Found in Cosmo Canyon when Bugenhagen is near
death. Red's Grandpa will give him the weapon before dying.
Gets its strength by having more MP. More MP=More damage
CAIT SITH
Marvelous Cheer
Found in Shinra's Headquarters on 64th floor
in the health spa. Located in the back of the lockers. 3rd row, left side
Powers up as Cait's Hp is closer to maximum
YUFFIE
Conformer
Found in the crashed Gelinka underwater, near
the Gold Saucer. Located in the generator room on the floor in the upper
left
The closer to Yuffie's own level the enemy is, the more damage it will
do
CID
Venus Gospel
Found in rocket town. Talk to the one man that
is near the item shop. Talk to him several times and he will give you Cid's
venus Gospel
The more MP you have, the more damage it does
VINCENT
Death Penalty
Found in cave near the Gold Saucer area. Enclosed
by mountains and water you need the submarine or gold chocobo. You also
need Vincent in your party. Visit the cave in disk 2, then again in disk
3 to get his Ultimate Weapon
The more enemies that Vincent kills, the more damage the weapon will do.
The more the other characters kill, such as if you don't let Vincent kill
any enemies, the weapon will gradually do less and less damage. Be sure
to let Vincent kill a few nasties.
