Jamirus is a Gryphon, having the head and wings of a mighty grey eagle and the body of a light brown lion. He stands upright and has a third eye. He is one of the Dread Fiends, based out of the Isle o' Smiles in the Upper World. His purpose is to entice gullible fools with rumors of the aforementioned isle, then sacrifice them to his master to strengthen him. In Dragon Quest Monsters: Joker and Joker 2, Jamirus is depicted with dark purple feathers on his head and wings rather than his usual grey.
Don't be fooled by its avian appearance—this beast is no birdbrain. It excels at arts both martial and liberal. It once served a demon king, stirring its fellow fiends into a frenzy with its rousing oration.
Jamirus is a S-rank monster of the Nature family, first appearing as a boss during the original Dragon Quest VI event. He can be faced in Chapter 2, Episode 4: Jamirus Appears reprising his role from the original game, as well as a boss in Free the Phantom Realm! Jamirus eventually appeared on his own banner alongside Mythsteed during the limited Mindini is Invincible in the World of Dreams!? event and he can also participate in the Sintaur's Battle Road as a party member.
