Im not sure what the music should be but this is my concept art Glitched Sans is following the order of the Glitch Hive (whatever the things called) He is killable but Still has the knowledge of his previous life and has the same skillset, He can still fight back, He can Still Dodge, But the only thing that others should fear about him is, The glitchy substance that hides within him, He can Corrupt you and make you become one with the glitch, Like a zombie the only goal he has in mind is making you one of him, He is hostile to people who aren't glitched but im not sure about error sans or fatal sans, Maybe he sees there glitchiness as a different kind and will try to glitch them once more? idk.
