His Djinn form can be seen when Muu executes Bard Romh to attack Aladdin. He is muscular, with spiky white hair, pointed ears, long fingernails, and a tail. There is also hair all along his arms, and what appear to be small wings on his legs. He wears a thick necklace, earrings, and a cloth around his waist. He has a somewhat crazed expression. Like all the Djinn, Barbatos has a third eye in his forehead.
Barbatos, along with the rest of the Djinn, were created by King Solomon from Rukh.
Barbatos' Metal Vessel is the sword that Muu carries with him. It is able to produce shock waves using Strength Magic that are able to fly to far distances. These shock waves can come in the form of whatever attack is used for eg. if a punch is used, the shock waves would look like a bullet but if a sword was used it would like like a slash of compressed air sailing towards the target. Each shock wave is easily capable of breaking a Borg and severely damaging the Magician.

—Muu, summoning the powers of Barbatos
Muu's Djinn Equip appearance is that of a lion. His hair becomes a long silver mane with two metal hair clips holding two bangs at the front, he has pointed feline ears, and feline-like feet covered in armor over the lower half of his body with wings at his ankles. He also gets a pair of wristbands connected to a pair of armbands by chains.
In this form, similar to a cheetah before running, his feline legs acts like a spring to increase his speed and power making him capable of crossing massive distances in an instant. They compare this to his body becoming a sword capable of breaking through anything.
It's been stated that he has a low quantity of Magoi since he's a Fanalis, and his Djinn Equip lasts no more than one minute. Although he might have more Magoi than the other Fanalis and Semi-Fanalis since he was able to conquer a Dungeon.
Djinn Weapon Equip
He compresses Barbatos' Strength magic around his Weapon changing it into a javelin. This javelin is capable of easily breaking through rocks and barriers in an instant with only a thrust.
- His name is probably taken from the book The Lesser Key of Solomon. In the first section of this book, entitled Ars Goetia, several demons are described, Barbatos being the eighth. As a matter of fact, the dungeon where Barbatos resided was the 8th as well.
