Description
Oscar Dragonia is an exorcist of the Abbey who holds the high rank of praetor and comes from the noble Dragonia family. He appears in the anime Tales of Zestiria the X as a supporting figure connected to the Abbey, the organization tasked with fighting daemons and keeping the world in order.

Oscar was born into the aristocratic Dragonia house and graduated as a first-class member of the nobility. His elder half-sister, Teresa Linares, took care of him from an early age, acting as both an older sister and a motherly figure. As an adult, he serves directly under Artorius Collbrande, a man he respects above anyone else. Before the events shown in the anime, Oscar oversaw operations at the Titania detention center, a prison island where Velvet Crowe was held. When Velvet escapes, Oscar is dispatched to Titania and confronts her and her companion Seres on the docks, demanding that Velvet return to her cell so that she can continue her assigned role of devouring daemons for the sake of world order.

In terms of personality, Oscar is cool, rational, and composed. He keeps his calm even in life-threatening situations, and this steadiness serves him well in battle, especially because he fights to protect people and to defend the world from evil. He holds a strong sense of justice as an exorcist and is deeply loyal to his sister. He also believes that everyone in life has a role to play, regardless of how much that person may resist it, and he treats certain painful actions as necessary sacrifices for the greater good. Despite his reserved demeanor, he is capable of genuine empathy; he is truly shaken by the death of Seres, someone he knew well.

His motivation centers on duty. He acts out of loyalty to Artorius and the Abbey, a conviction that order must be maintained, and a desire to protect the world from daemonic evil. This makes him a firm opponent of Velvet, since her escape and her path of vengeance directly challenge the system he serves.

In the story, Oscar functions as an antagonist and recurring obstacle. He first appears trying to stop Velvet as she flees Titania, and he encounters her on several later occasions as well. His position as a praetor-rank exorcist places him among the Abbey's strongest agents, and he carries out his missions with discipline and a strong sense of purpose.

His key relationships shape much of his behavior. Teresa Linares is the person he is most loyal to, having been raised by her as a devoted younger brother. Artorius Collbrande is his commander and the figure he admires the most, and Oscar carries out Artorius's orders without question. His relationship with Velvet is adversarial, defined by his repeated attempts to bring her back under the Abbey's control. His connection to Seres is more personal, and her death affects him deeply, revealing the emotional side beneath his composed exterior.

Oscar's development comes through these cracks in his discipline. He begins as a rigid enforcer of the Abbey's will, but his shock at Seres's death shows that he does not take loss lightly and that he feels the weight of the sacrifices his duty demands. This tension between devotion to order and his underlying humanity makes him a more complex figure than a simple loyal soldier.

In combat, Oscar is a skilled swordsman and a first-class daemon executioner. He fights with a flat-ended sword, a choice that reflects his preference for avoiding unnecessary harm, though he is fully capable of using it decisively when a situation turns serious. He also commands malakhim, servant spirits who support him in battle, giving him reinforcements when he confronts powerful opponents. He is a young man with blonde hair and green eyes, standing about 1.75 meters tall, and his bearing reflects the discipline of his noble upbringing and his rank within the Abbey.
