Diamond Weapon (Final Fantasy XV)

Concept art for Kingsglaive: Final Fantasy XV.

Finally, my daemon-infused magitek armor is complete. I have christened my creation 'Diamond Weapon.' It has exhibited an extremely unstable psyche, immediately unleashing unmitigated horrors upon activation. Its destructive capabilities, however, are indeed beyond compare. Not even the 'impenetrable' Insomnia could withstand its onslaught. Why, the Crown City would fall in a mere matter of minutes.

Research log: Year 756, Day 98 in Episode Prompto

Diamond Weapon is a colossal magitek monster created by Verstael Besithia in the Final Fantasy XV Universe. It appears in Kingsglaive: Final Fantasy XV movie, and is mentioned in Final Fantasy XV: Episode Prompto. It is based on the Diamond Weapon boss from Final Fantasy VII. It is not named in the movie, but is referred to by the codename "Diamond Weapon" in Episode Prompto.

Profile

Concept art.

In his correspondence with the emperor, Verstael refers to the Diamond Weapon as a "daemon armor", implying it is created similar to how magitek troopers are made, by powering a magitek core with miasma, the black mist emitted by lifeforms parasitized by Starscourge. Diamond Weapon is a monstrous creature that towers over buildings. It has a glowing red sphere in its chest, and a another such orb on its forehead. These might be the magitek cores that power it. It has shoulder appendages that open up and shoot salvos of energy beams, demolishing everything in its path. It moves bipedally and has an appendage on its back that resembles a cape.

Story

On 8th of April M.E. 756 Verstael informed Emperor Aldercapt that the Diamond Weapon was ready and asked him to come view the new weapon at First Magitek Production Facility. It is possible that it was created by Verstael by intentionally daemonifying the researchers working at the production facility, as the final cohesive message left behind by a team member, dated 12th of February, is: We are all... Together, we...Insomnia. As the ultimate...we... Thank you... Farewell...

Diamond Weapon is deployed to terrorize Lucis at the behest of Niflheim. When the Kingsglaive engage the empire in Duscae region, the sun sets and the empire deploys a Diamond Weapon upon them, but retreats after demonstrating its superiority to the Lucian forces. During the invasion of Insomnia, Niflheim deploys multiple Diamond Weapons against the Old Wall statues.

When the sun rises on the devastated Insomnia, the Diamond Weapons are gone. Whether Diamond Weapon can only be deployed at night is ambiguous, as even though the magitek armor is said to be lightproof, Diamond Weapon is only seen deployed at night in the movie.

Creation and development

Concept art.

The Diamond Weapon for Kingsglaive: Final Fantasy XV was sculpted by József Czakó at Digic Pictures based on concept art by Square Enix. Digic Pictures produced the battle scene where Diamond Weapon emits smoke (or possibly, miasma). In the final battle scene (made by Image Engine), Diamond Weapon appears without the smoke, and the artists working on that scene further improved the texture and surface of the model.

Trivia

Sketch of Diamond Weapon in "Episode Prompto".

• The artworks of Diamond Weapon seen on the documents in Episode Prompto are the concept art made for Kingsglaive: Final Fantasy XV.
