Ultimate Weapon is one of the “weapon” bosses that come out of the Northern Crater after Sephiroth receives the Black Materia from Cloud. Your first encounter with Ultimate Weapon is in Mideel when the team is attempting to rescue Cloud. It flies away before you can finish it off…

The terminology can get a bit confusing due in part to everything being named the same thing. Each character has an Ultimate Weapon, and Cloud’s Ultimate Weapon is called Ultima Weapon. You receive it for defeating a boss named Ultimate Weapon, described below. Confusing!

You can find and defeat Ultimate Weapon anytime after you defeat Diamond Weapon during its attack on the city of Midgar. However, it’s best to leave this battle until later in the game, as it becomes much easier.

Where to find Ultimate Weapon

Ultimate Weapon first appears in a huge crater just to the east of Junon. You will have to battle it several times as it will flee from battle a few times, just like it did in Mideel.

After your first battle, it will start flying randomly around the world map, darting back and forth, though it respawns at this crater each time it disappears from your sight, so if you can fly back to this area quickly enough, you can initiate the next battle much more easily.

The actual battle against Ultimate Weapon is fairly straightforward. It does have a few powerful attacks, so keep your party healed up throughout the fight. Ensure you equip Long Range Materia on your characters, as you will be fighting some of these battles from the deck of the Highwind, which will prevent melee characters from using regular attacks.

It has approximately 100,000 HP. However, it does not heal itself after each fight, including the battle at Mideel. Focus on using your hardest-hitting spells, abilities, and summons to do as much damage to it as you can before it flies away.

Find Ultimate Weapon flying around the world again and bump into it a few times until it flies directly to its next destination, which will either be:

• Mideel
• Mount Nibel
• North Corel
• Gongaga Village
• Fort Condor
• Midgar
• The Northern Crater

Slam into it one more time once it arrives at its destination to begin the next battle. It can be pretty challenging to track down Ultimate Weapon at times, and, unfortunately, there are no shortcuts to finding it wherever it has flown on the world map.

The final battle takes place near Cosmo Canyon, and Ultimate Weapon will head straight there once it falls below 20,000 HP. It will not escape from this fight.

Be careful because Ultimate Weapon will use Shadow Flare as its last attack before it dies on one of your characters. It casts it on the character who lands the killing blow, and the Shadow Flare skill can be picked up and learned through your Enemy Skill Materia. The reward for defeating Ultimate Weapon is Cloud’s Ultimate Weapon called Ultima Weapon.

A huge crater will left on the ground after the battle has concluded. This new crater provides you with a pathway to reach the Ancient Forest. Check out the Ancient Forest side quest page using the link below for more information:
