Sir Arthur Hellsing

Sir Arthur Hellsing was the head of the Hellsing family and was also the father of Integra.

History
Early Life

Not much is known about Arthur, but when he was a young man he became friends with his friends and future colleagues Sir Hugh Irons and Sir Shelby M. Penwood. He would eventually succeed as the Hellsing family's new head.

Hellsing: The Dawn
During the events of Hellsing: The Dawn, he assigned 14 year old Walter C. Dornez and Alucard to destroy a vampire research facility in Warsaw in order to stop the Nazis from deploying their experimental Ghouls to the battle field. If allowed to continue, the Ghouls would keep growing infinitely, because normal infantries wouldn't be effective against them and would turn the tides of World War II. Despite doubt from members of the Round Table, Arthur was sure that Walter would succeed in the mission.

According to Sir Hugh Irons, Arthur came to believe that Alucard was "too powerful a drug to be used as more than the occasional medicine", and Alucard was sealed and locked in the Hellsing Mansion's dunegon in 1969.

20 Years Later
Over the course of the next 20 years, Arthur married and had a daughter named Integral (nicknamed Integra). In 1989, Arthur contracted an uncurable disease. On his death bed, Arthur entrusted Integra as the new head of the Hellsing Organization, much to his brother, Richard Hellsing 's displeasure.
