Godzilla/Headscratchers


 * The "Oxygen Destroyer" from the original Godzilla film. They dump it in the ocean. Which is made up (mostly) of Hydrogen and Oxygen. Wouldn't an Oxygen Destroyer destroy all the oxygen in the water, turning it into pure Hydrogen?
 * It's explained in the film that the Oxygen Destroyer is a chemical that breaks down oxygen molecules within a small radius causing asphyxiation among other things. That would mean that, yes, the area would be filled with hydrogen, but it probably wouldn't be that noticeable.
 * Fridge Brilliance: All the bubbles in the water during its activation could very likely be hydrogen.


 * This occurs in both Godzilla vs King Ghidorah and Final Wars. The heroes release Godzilla to fight the villain's monster or monsters, and then the villains stupidly order their monster to go kill Godzilla. Why? It seems that Godzilla in these instances is not friendly to humanity and in both cases the villains just want to cause the destruction of major cities. They should have done the opposite and ordered their monsters to avoid Godzilla as much as possible, then both monsters would be free to cause destruction without interference.
 * Godzilla is extremely territorial. He also has a sort of sixth sense that lets him detect and home in on another monster. Even if the bad guys tried to leave him alone, Godzilla would track them down and destroy them anyways.
 * 'Cause Japan is Godzilla's own 'hood, and ain't no-one trashin' his home turf!
 * Also, in Final Wars, the Gotengo was directly leading Godzilla towards the monsters and the Xilian Mothership, even if X hadn't sent monster after monster after Godzilla, he'd ultimately have ended up having all his monsters fight him anyway. He was just being proactive and possibly buying time for Gorath to arrive with Monster X or for Gigan to be salvaged and repaired.
 * Except in both cases Godzilla would be unable to follow the monster in question. King Ghidorah can fly faster than Godzilla can swim or walk, making it easy to stay ahead of Godzilla while still allowing Ghidorah to freely destroy cities. In Final Wars, the monsters were held in stasis aboard ships until they were teleported to Godzilla's location. If they stayed aboard those ships then Godzilla would be unable to fight them.
 * Yes, but Godzilla would have then just gone straight to the Futurians/Xilians and attacked their ships. And remember that in both cases humans helped Godzilla by teleporting the Futurian ship to his location and leading Godzilla to the Xilian mothership.


 * Why was Dr.Serizawa so concerned about what could be done with the Oxygen Destroyer? It only works underwater, so unless Atlantis is real, it can't really do that much damage.
 * As a survivor of one of the nuclear bomb attacks on Japan, Serizawa was deeply conflicted because he was trying to create something beneficial to the world (a clean source of energy) but as it was only half finished it was only useful as a weapon. You know, just like a nuclear bomb. He was like a Japanese J. Robert Oppenheimer, but he didn't want his invention to become a weapon like that. And if you think an "oxygen destroyer" would only work in the water ... uh, what are you breathing right now?
 * Hell, in Godzilla vs. Destroyah, one of the characters outright states that if it were used on land Tokyo would have been turned into a Mass Grave.
 * Even if it only works in the water, the heck does it make it not a super weapon. Whoever owned could just toss it into the water and voila, all the ships in the area would sink straight to the bottom.
 * There's also the proliferation factor. Think of the aforementioned Oppenheimer's concern about the atomic bomb. Science will not only build more superweapons, they will built exponentially more destructive superweapons.
