The central figure of the comedy anime Don Dracula is Count Dracula, a vampire who finds himself far from his native Romania and trying to adapt to a new life in the Nerima District of Tokyo. Having lived for approximately four hundred years, he is a member of the noble Dracula family, a lineage he takes great pride in, though his circumstances have become far from grand. He relocated to Japan following his daughter, Chocola, and his loyal servant, Igor, with his entire house apparently being moved by a Japanese business interest. This relocation was not a triumphant arrival, as practically no one in Japan believes in vampires, leaving the Count feeling uneasy and out of place in his new surroundings.

In terms of personality, Don Dracula is a complex blend of traditional aristocratic pride and sheer misfortune. He is notably prideful and aggressive, often acting snobbish about his noble bloodline, and is quick to anger when he feels it has been mocked. Despite this grand self-image, he is also deeply pathetic and unlucky, a fact that serves as the primary source of the series' humor. His attempts to act like a fearsome vampire are consistently undermined by his own carelessness and an unfortunate fate that seems to follow him everywhere. He has a particular weakness for beautiful women, though his perverted attempts to charm them typically end in failure. He views humans as weak beings, yet ironically, he often ends up saving human lives completely by accident, which contributes to his nature as a comedic anti-hero.

Don Dracula's motivations are largely driven by his basic instincts and paternal duties. As a vampire, he seeks to drink blood, but his efforts are perpetually thwarted. More genuinely, he cares for and protects his daughter, Chocola, a half-vampire, half-werewolf. His role in the story is that of an unlucky protagonist whose daily life is a series of misadventures. His primary goal is often simply survival, as he is constantly hounded by two relentless pursuers. The first is his longtime nemesis, Professor Van Helsing, a vampire hunter who is himself somewhat pathetic due to a painful struggle with hemorrhoids. The second is an overweight and unattractive woman named Blonda, who became obsessively fixated on him after he bit her, and she stalks him relentlessly.

The Count’s key relationships define much of his character. His relationship with his daughter Chocola is his most genuine and redeeming quality; he loves her, worries about her safety among humans, and is a protective father figure. The origin of the Dracula family dynamic is also defined by his past relationship with his ex-wife, Carmilla, a werewolf vampire. They divorced three hundred years earlier, when Chocola was still a baby, due to fundamental disagreements over how to hunt humans, as Dracula found her methods unacceptable. His servants, particularly Igor, assist him, but his life is made far more difficult by his enemies, Van Helsing and Blonda, as well as his own incompetence. The series does not feature significant character development, as it is an episodic slapstick comedy, and Don Dracula remains a static figure whose unlucky nature and prideful personality are consistently played for laughs. A recurring gag involves him being killed by his various weaknesses, such as sunlight, water, or crosses, only to be later reincarnated in equally unlucky circumstances.

As a vampire, Don Dracula possesses several notable abilities typical of the mythology. He can transform into a bat, an ability facilitated by his mantle. However, his powers are counterbalanced by an extensive list of traditional weaknesses, including an extreme vulnerability to sunlight, water, crosses or cross-like shapes, and loud noises, all of which are frequent sources of humor in the story.
