The Anti-Gunner
Read the full story on AO3: (Tail Gunner)The Anti-Gunner
The Anti-Gunner is the cosmic judge of the universe created by The All-Gunner, A Gunner of animal intelligence and gentle nature. Her soul is loaded into the Revolver of Judgement and fired at a planet that has been picked for judgement as deemed by The All-Gunner. Once on the planet, The Anti-Gunner typically acts like a dog or some other form of mammal. It searches for food, eats, drinks water, and sleeps a lot when it finds shelter. She doesn't speak, can't understand language, and makes animal noises or barks. She is also indestructible, immortal, and can't die. Most planets make the mistake of opening fire once they see her, signing their death warrant. One hit and she kills you, no matter what you attack her with. War mongers, cruel tortuerers, hateful societies, racists, and disgusting planets are quick to fall, others survive by sheer luck, some fear her and give her food/worship, while others ignore her presence entirely. The results depends on the planet and vary wildly. Every planet has a different account/story/image of The Anti-Gunner.
The planet visited the most is planet Yorsa, home of the Yorseers. The Yorseers are a war mongering race of furry creatures whose entire culture revolves around military, war, guns, and killing. From birth to death, you are a soldier and nothing more on the planet Yorsa. The Anti-Gunner visited them twice already and had no effect. By the third judgement, with Sophie involved, The Yorseers were annihilated and finally judged.
The Demi-Gunner Luau is a former Anti-Gunner who lived peacefully for a few million years and evolved to become the Demi-Gunner Luau. There have been a few Anti-Gunner cycles where many have evolved/asceneded, but it is very rare. Most deliver judgement and dissolve away into a fossil once their destruction is complete.
