Morgana is a character in Persona 5. He is a strange catlike being first met by Joker and Ryuji at Kamoshida's Palace, and he joins the Phantom Thieves after that. His codename is Mona. Despite looking like a cat, he does not like being referred to as such.
Morgana appears as one of the DLC Spirits added with Joker's appearance. He also appears in the Phantom Thieves of Hearts Spirit.
Morgana, under the name Mona, was added alongside several other characters from Persona 5 during the Caged Desire event.
A talking cat (don't say that to his face) who has served as the guide and mascot of the Phantom Thieves ever since Joker saved him from Suguru Kamoshida's Palace. Has a mildly unhealthy obsession with Panther.
