Oxygen Destroyer

The Oxygen Destroyer (オキシジェン・デストロイヤー Okishijen Desutoroiyā) is an Anti-Titan weapon of mass destruction that cameoed in Godzilla: Lord of the Galaxy.

Created by the EDF, the Oxygen Destroyer was the deadliest weapon they have created. It is unclear on what the Oxygen Destroyer was used on, but the Oxygen Destroyer spawned in a Supertitan mutated from it: Destoroyah.

In 1995, Destoroyah killed Dagon, but was later defeated by Rozan with the help of Mothra.

In modern day, the scientists in the EDF's Tokyo Base mention that weapons like the Oxygen Destroyer shouldn't have existed in the first place.

Design
The Oxygen Destroyer seems to retain the missile shape of its MonsterVerse counterparts, but its insides are that of the 1954 film. It is a heavy device composed of a metal capsule with a glass central chamber. Within this chamber is a second capsule attached by rods at either end. Contained within the capsule is a large amount of chemicals, which would be the weapon's payload. Numerous gauges and pressure meters are present on the larger capsule. To operate the Oxygen Destroyer, the two ends of the larger capsule have to be pushed inwards. This causes the rods securing the inner capsule to pull apart, releasing the chemical within.
