Baal is a high-ranking demon who serves as one of the Thirteen Crowns, the governing body of the demon world, and holds the title of Thunder Lord. He commands the Demon Army of the South and is recognized as the Tactician of the South for his strategic mind. He founded the Magical Apparatus Battler at Babyls Demon School as a front to recruit followers for his personal ambitions.
He possesses pale skin and spiky blond hair, with two distinctive strands shaped like lightning bolts framing his face. His eyes are sharp and gold, complemented by pronounced eyelashes. He typically wears a black jacket with white fur around the neck and matching black pants.
Arrogant and prideful, Baal exhibits a profound lack of empathy. He is dismissive of subordinates and peers alike, often displaying cruelty and a competitive nature. Behind this brash exterior lies a shrewd and cunning strategist, capable of masking malicious intentions with charm or irritability. He is a patient long-term planner but possesses a short temper, particularly with his protege, Kirio. A skilled actor, he maintains a deceptive image as a supportive uncle to his nephew and niece while manipulating events toward his goals.
His primary ambition is to return the demon world to an ancient state of chaos and savagery, rejecting modern order. To this end, he leads the clandestine Demon Reformation, or Return to Origins movement, masterminding schemes to instigate chaos, including plots to destroy Babyls Demon School and undermine the demon ranking system.
Baal attended Babyls Demon School, where he established the Magical Tools Research Battler and first encountered the child Amy Kirio. He took Kirio under his wing, nurturing his twisted nature and providing devices to amplify his magic. A member of the Sabnock family, he is the non-blood-related uncle of Sabro and Silvia Sabnock. His relationship with their father, Sabzan, is strained, with Sabzan demanding he stay away from the family.
He orchestrates multiple major events, engineering a plot to destroy Babyls during the Battler Party by using Kirio to trap students inside a barrier with a bomb—a plan thwarted by Iruma Suzuki. Baal later deduces Iruma’s human identity from a recorded conversation and prioritizes capturing him for his potential to fuel chaos through the consumption of human flesh. He manipulates political structures within the Thirteen Crowns, proposing his nephew Sabro as a candidate for Demon King—who refuses—and gains influence through engineered heroics, such as defeating the rampaging Behemolt at the Deviculum to win support from other deities and Crowns.
Baal wields electrokinetic abilities, generating and manipulating lightning, consistent with his Thunder Lord title. As a member of the Thirteen Crowns, he commands significant demonic power and influence.
His relationships are largely transactional and manipulative. He commands the Six Fingers, a group of elite operatives, treating them with brutality but valuing their effectiveness. He maintains a complex dynamic with Kirio, acting as a mentor and older brother figure while scolding him for failures. Baal withholds critical information, such as Iruma’s humanity, from subordinates for strategic reasons. Among the Thirteen Crowns, he feigns arrogance and disrespect to conceal his intentions, maintaining a professionally functional relationship with figures like Azazel Henri.
His role expands as he gains prominence within the Thirteen Crowns, rising to a position second only to the Three Greats. He continues to orchestrate schemes from the shadows, leveraging allies like Naberius Narnia, who joins the Crowns through his recommendation under a mutually beneficial but manipulative arrangement.
