Damnit, I need to move fast
I quickly create an intense torrent of fire around the room, destroying the bodies and spores before it instantly dissipates. More attention is required here to get rid of the goblins without harming normal people, but that's fine.
I can do that and still get out of here before the other commander. In fact, distantly from the shadow drone, I can feel a goblin rushing over to the leader in Japan. I can still deal with this, I just need to get rid of the messenger in a way that won't be noticed. The drone rushes through the shadows and the materials of the building, eventually finding a goblin with obviously and urgently rushing to inform the leader of my actions. Even through the drone, my perceptions are far faster than its movement, making anything I could do to it totally unavoidable. Until I have an opening, I observe the goblin's internal structures to learn the materials that compose it and its spores.
Waiting until there aren't any witnesses, goblin or otherwise, I make my move. My observations allow me to turn all but the most convoluted biological materials composing the goblin and its spores to shadow, which is immediately dispersed into the shadow of the building in general. This makes it darker, but not by any amount visible to a human and, even to one with as precise a sense of sight as myself or the others, would be barely distinguishable from the natural variance in the "darkness" of the shadow caused by hoe light moves through the atmosphere. The portions of the goblin left are around the size of its normal cells or smaller, as many of the more complicated processes found within were beyond my slap-dash analysis.
