Glasya-Labolas' Metal Vessel is Barbarossa's poleaxe.
Barbarossa is able to perform a Half-Djinn Equip complete with his weapon. In this form, he is able to equip half of his body, with his right side being normal and his left side being that of a Djinn. In his Half-Djinn Equip, Barbarossa has wings and five eyes on his torso and either side of his head, as well as flame-like designs all over his body. His poleaxe turns into a large spear with the eight-pointer star in the middle. He also has a mandala behind his head and another on his weapon.

—Barbarossa, summoning the powers of Glasya-Labolas
- Hadith Barad Iltehad (Steel Sweep Scatter)
- Barbarossa uses the power of his Djinn to create metal bullets and send them at the opponent. This attack was powerful enough to pierce through Drakon's body in many places.
- This Djinn's 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, Glasya-Labolas being the twenty-fifth. The dungeon where Glasya-Labolas resided was the 25th as well.
