Captain Von Jobina, also known as Bon Jovina, holds the position of Captain of the Guard in the kingdom of Meta-Ricana. His name is a reference to the musician Jon Bon Jovi. In his role, he is depicted as a dedicated if unfortunate officer, whose primary allegiance is to the princess of Meta-Ricana, to whom he remains fiercely loyal.

Von Jobina's personality is largely defined by his rivalry with the series' protagonist, Dark Schneider, for whom he harbors a strong dislike. Despite this personal animosity and a tendency to be easily overwhelmed by powerful foes, his core motivation remains the protection of his kingdom and his duty to the princess. His role in the story often places him in the path of dangerous enemies, serving as a resilient obstacle who frequently endures tremendous punishment.

Key relationships include his deep loyalty to the princess and his adversarial stance toward Dark Schneider. Regarding character development, Von Jobina is shown to be exceptionally durable, surviving a series of catastrophic injuries that would be fatal to most individuals. These include being crushed by a Hydra, struck by a Minotaur wielding a giant war hammer, flattened between two walls, and blasted through two walls by a technique known as the Hurricane Sword. This remarkable resilience is his most notable ability, allowing him to continue his duties despite constant defeat. Later, he is depicted in the Halls of Gathering alongside other half-human races from around the world, participating in discussions on how to confront an upcoming battle.
