While appearing to be a cat-like creature, Morgana emphatically insists to be a human, and sticks with the Phantom Thieves as he believes they'll be able to help him discover his origins and regain his true form. Despite this, sometimes he instinctively meows and self-grooms, being able to get used to his lifestyle as a cat easily. However, he demonstrates a number of qualities which are absent in ordinary animals - a sense of morality, empathy, and even style. But even though Morgana's intelligent, he's shown to be out of touch with the modern world. This is conveyed through his unfamiliarity with technology, and his initial assumption that his knowledge on the Metaverse is supposed to be common sense. In this game, he along with the Phantom Theives infiltrate a base believed to be a Palace, but however turned out to be a trap, scattering the thieves to various locations in the World of Trophies, after waking up from the incident, Morgana finds himself overwhelmed by powerful puppet fighters until he gets the unexpected rescue from a spiky haired boy welding a giant key, accompanied by two creatures who are just as bizarre as he is!

While he sounds like a young child, he surely doesn't act like one! He's quite informal and supportive of his allies too!
