Of course, they'll want to use it as a weapon. Bombs versus bombs, missiles versus missiles, and now a new superweapon to throw upon us all! As a scientist - no, as a human being - I can't allow that to happen! Having devoted his studies to the element oxygen, Serizawa accidentally stumbled upon a volatile and deadly chemical reaction. Though horrified by the destructive potential of his discovery, he nonetheless continued his research, optimistic that some beneficial outcome could be produced from it. Design The Oxygen Destroyer 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 what would be later known as , 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 Micro-oxygen within. History The Oxygen Destroyer is activated on the bottom of in The weapon was first revealed to by when they were in his lab. He demonstrated it on a tank of fish, which were instantly reduced to skeletons, much to Emiko's horror. After destroyed , Serizawa reluctantly agreed to allow the Oxygen Destroyer's raw form to be used against the kaiju, but only after destroying his research documents and materials. The formula was still in his memory however, and fearing that it would lead to another arms race, the doctor knew that he would need to sacrifice himself as well. On the fateful morning in Tokyo Bay, Serizawa and descended into the water to find Godzilla, with Serizawa carrying the Oxygen Destroyer. Soon, Godzilla was located, and despite sighting the two divers, the monster was apparently unaware of their presence. Serizawa activated the device, then urged Ogata to return to the boat. As Ogata was pulled upwards by the boat's crew, Serizawa set the device down and then cut his diving suit's air tube. As the Oxygen Destroyer released its payload of Micro-Oxygen, Serizawa stood and waited to be disintegrated by the corrosive chemical. In bouts of horrendous pain, Godzilla surfaced from the water and uttered one final roar before sinking back into Tokyo Bay. As the Micro-Oxygen continued to take effect, Godzilla's flesh was dissolved completely, followed by his skeleton. Both the monster and the brilliant scientist were no more. Emiko begged Yukari and to convince Ijuin to shelve the project, since Serizawa had given up his life to ensure that the Oxygen Destroyer could never be used again for any purpose because of how dangerous it was. Despite their aunt's pleas, Yukari and Kenichi attempted to convince Ijuin to recreate the Oxygen Destroyer, believing it was the only way to stop Godzilla's impending meltdown and save the world. Ijuin revealed another concern, a lifeform had escaped from a soil sample recovered from the site where the Oxygen Destroyer was detonated to kill the first Godzilla in 1954. Soon, Ijuin was called to investigate when all of the fish in a local aquarium were mysteriously killed. Ijuin determined that the fish were killed by several microscopic creatures that had been mutated by the Oxygen Destroyer and were coming ashore due to the presence of micro-oxygen. These creatures began combining with each other into larger and more fearsome forms and wreaking havoc, eventually combining into a gigantic living incarnation of the Oxygen Destroyer, which Ijuin named. G-Force had and use their telepathy to lure to Tokyo, knowing Godzilla would follow. Junior was attacked by Destoroyah and managed to defeat him after a brutal battle. While Godzilla and his adopted son tried to reunite near , they were attacked by Destoroyah in his Perfect Form, who killed Godzilla Junior and battled Godzilla. When Godzilla's temperature reached critical, Destoroyah tried to fly away, but was shot down by G-Force's freezer weapons and collided with the superheated ground, vaporizing him and ending the Oxygen Destroyer's destructive legacy once and for all. In the continuity of , the Japanese government covered up the use of the Oxygen Destroyer against Godzilla. It was feared that the military would face ridicule over its inability to defeat Godzilla and thus the were officially credited with the victory. The Oxygen Destroyer is used against in a flashback in In , the Oxygen Destroyer didn't dissolve Godzilla's skeleton, and 's blueprints incorporated the original Godzilla's skeleton within it to make the design process and construction less strenuous. Mechanisms The device works by activating a chemical stored within its spherical center, which causes the center to split in half and open. Once released, the chemical later dubbed by reacts violently with the water, isolating oxygen molecules and splitting them. The molecules are then liquefied. This means that any organism exposed to the chemical will first suffocate from the lack of oxygen, and then disintegrate. Depending on the amount of the oxygen destroying chemical released, the body of the victim will either be eaten down to the bone or destroyed completely. When used to its full potential, the Oxygen Destroyer will leave no remains. Ijuin, if the Oxygen Destroyer had been used on land, it would have turned Tokyo into a cemetery. Creatures that thrive in anaerobic environments, however, such as the Precambrian crustaceans that became , can actually be empowered by the Oxygen Destroyer's chemical reactions and mutate to incorporate Micro-Oxygen within their bodily processes. The destroyed his blueprints before committing suicide as the weapon activated. Godzilla's fate was left ambiguous; either he survived or another monster of the same species appeared several months later. For his most devastating attack, he holds it above his head as it spews lightning bolts in every direction. Other props from the original film that were intact as of were a diving helmet and pair of boots. References This is a list of references for Oxygen Destroyer.
