Barbarossa (バルバロッサ, Barubarossa) is a lieutenant of the Parthevia Empire, head of the Dragul family and Drakon's elder brother. He is one of Judar's King Vessels and a Dungeon Capturer, capturing one Dungeon.
Barbarossa has short cropped hair and bangs that cover his forehead up to his eyes, which look similar to a dragons. He has an earring with a chain and a jewel at the end like his brother, Drakon. His usual attire consists of his Parthevian military uniform.
In a flashback, although his appearance was not given at the time, he gave off a cold and manipulative attitude when talking about his betrothal to his fiance Serendine Parthevia. He has no qualms about breaking the news to Serendine that her father had "unfortunately" passed away before the day of their wedding, and allowed his Household to attack his little brother Drakon and Serendine's handmaidens. Barbarossa does not care at all of Drakon and was willing to kill him in cold blood while using his Djinn Equip.
However, Barbarossa did show a respective side towards Judar, as he apologized for causing a ruckus in his equip and waking up Judar because of his Rukh.
Glasya-Labolas is the Djinn of Slaughter and Arrogance, whom Barbarossa received after he captured the 25th Dungeon. The metal vessel for the Djinn is Barbarossa's poleaxe.

—Barbarossa, summoning the powers of Glasya-Labolas
- Djinn Equip: Barbarossa can utilize half of his Djinn Equip form. When activating this ability, his armor melts and liquefies. He gains a robe and a rhakkhara. He is not able to use complete Djinn Equip, however, he is strong enough to defeat Drakon with ease. His magic type is unknown but related with steel.
- Hadit Barad Iltehaq (Steel Sweep Scatter): Barbarossa uses the power of his Djinn to create huge steel bullets and fire them at the opponent. This attack was powerful enough to pierce through Drakon's dragon armor in many places.
He does not think highly of his little brother, being willing to write him off as dead when he went to capture Valefor's dungeon and never returned. He also held no qualms about performing his Djinn Equip and using it to attack Drakon.
He pretends to have a warm personality around the princess, prior to their wedding ceremony and treated her with kindness. Although later when he attacked Drakon, Serendine said she would null their marriage and would make sure her father heard of what had done, he showed his true colors. In reality, he only cares about Serendine as a tool for him to get to the Parthevian throne, making him king and her, his empress.
It is unknown whether Judar personally chose Barbarossa as his king candidate or happened to be in Parthevia at the time of the wedding ceremony. However, he treats Judar with respect as a Magi, even telling Judar he would stop using Djinn equip because it disturbed Judar's rest. Judar, for his part, affectionately refers to him as "Bar".
- His name means "red beard" in Italian. This may refer to Frederick Barbarossa, Holy Roman Emperor from 1152 to 1190.
- He is noticeably similar in appearance to Seto Kaiba from the Yu-Gi-Oh! series.
