Better known as Alucard , is the dhampir son of Dracula. As the offspring of an unnatural bond between Dracula and a human woman named Lisa, Adrian had special powers and was destined to be stronger than any human but not potentially as strong as his father. After Lisa was killed, having been mistaken for a witch, Adrian grew up under the influence of his father, whence he was taught in the dark arts and molded into a warrior who would one day fight for the side of evil.

Adrian's existence did not come without quirks, as the gentle, human side of his mother always seemed to cloud his "better judgement", as Dracula would have put it. At her death, Adrian was by his mother's side. She insisted that he not take his anger at her death out on the humans, as their lives are already full of hardship. With those words, she had a profound influence on Adrian's thinking. His mind wandered as he questioned his father's will. After standing by for as long as he could, he broke away from his father's army and disappeared. Understanding that Dracula was going to impose his wrath on the people, Adrian would turn his efforts toward destroying his father's army, hopefully encouraging him to reconsider. Furthermore, he chose to go under the name "Alucard" –Dracula's name in reverse– to represent that he stood for beliefs opposite those of his father.

Alucard is an adept swordsman and typically wields one-handed swords. Alucard's other attacks use dark magic. As a shapeshifter, Alucard can change himself into a bat, a wolf, or even mist. In 1476, when Trevor C. Belmont was on his own quest to hunt out Count Dracula, who had manipulated his own son into fighting for evil, Alucard would be waiting for Trevor to come by. Alucard challenged him to a fight at this point to test the hero's skills. Alucard was surprised by Trevor's strength when he was bested and asked Trevor if he could join him on his quest.

After helping to destroy Dracula, and despite his good intentions, Alucard couldn't help but feel guilty for having committed patricide. To ease his pain, he put himself into a deep slumber, submerging his powers. In 1797, due to the unexpected lack of a Belmont, Alucard had no choice but to awaken from his slumber to investigate the matter and infiltrate Castlevania. He has long, flowing blonde hair that reaches his shoulders, and his facial features are sharp and well-defined. He is wearing a detailed, formal outfit that includes a high-collared black cloak with gold and yellow accents, adding a regal touch to his attire.The inner part of his outfit appears to have intricate designs and patterns, with metal clasps running down the front. He also wears a white cravat or ruffled shirt underneath.
