I’ll admit, the whole “cameras don’t work” thing was a bit of a cop out on my part. Because it has to do with the magic parents and the ritual and it was… Well, not unrelated, but tangential to the story I wanted to tell.
Basically, the kaiju masters were using the magic parents to fuel their invasion–using dragon!Maleficent’s DNA to create magic resistant kaiju, Jafar’s mind control to… well… control the kaiju, and Ursula and Grimhilde to keep the tears open and other stuff. Essentially, Carlos had the jaeger program and all the stuff from Ben while the kaiju masters had the magic villains. It’s part of the reason why Mal, Evie, and Jay were being hunted because they are three more magical batteries for the kaiju masters.
So what the Dragon Knight did was to free the magic parents from however the kaiju masters were controlling them, thus also freeing the kaiju and it kind of turned into a bloodbath on that side with everyone fighting each other and Dragon Knight preventing kaiju from going through the tears then racing to go through one themselves before all the tears collapsed/disappeared.
