I've been seeing the glich theory for Ignis and i think he may actually be a glitch because of his lack of pattern. All the other AI's have triangle patterns on their bodies, but Ignis has none. Plus, the Cyverse world is very sleek and sharp and bright, but Ignis is more rounded and darker in muted colors. He doesnt fit into the world of Cyverse and the other AI's. Plus, he's still referred to as Mysterious Lifeform in official news, so maybe he's something different?
