I made my own undertale au! There name is Guardian and they purify corrupt Aus, killing the genocide players and taking their souls. Then there's overwrite, who destroys corrupt Aus when they can't be saved. Its like ink and error but they work together. And finally there's rewrite, who corrupts Aus wherever he goes. Implementing the idea of a genocide into the players mind, purely for amusement purposes. Guardian and overwrite are on a constant search to stop overwrite. They have run into ink and error fighting before, they always take inks side in battle when they have to.
