Mina Harker

Wilhelmina "Mina" Harker (née Murray) one of the main protagonist in Bram Stoker's novel Dracula and a crucial instrument for Millennium in Hellsing. In the novel, Dracula had attacked her and forced her to drink his blood. This had connected her mind to Dracula's, allowing Abraham Van Helsing and the others to track his movements and follow him. In the end, Quincey Morris and Jonathan Harker kill Dracula, Mina subsequently regains her humanity, and later she bears a son.

In Hellsing, the end of Dracula greatly deviates from the original. Van Helsing is the one who defeats Dracula by punching a stake through his heart, but does not kill him. As such, Mina Harker remains a vampire, though the events that occur between the end of "Dracula" and the beginning of "Hellsing: The Dawn" are not entirely clear. She first appears in Chapter 1 of "The Dawn" as a contorted figure wrapped in bandages and chained to a wall. She appears again in Chapter 2, in which the Doctor describes her as "perfect" and "horrible". He cannot believe that she exists, even after studying her. The Major refers to her as "our beginning and our end" and says that "once before, sanity and insanity fought over her," that "they trampled her underfoot," and that "she is just what is left over." It is assumed that "She" is the original vampire upon which all of Millennium's artificial vampires were based. In Hellsing, Chapter 93, "Sorcerian 2," the Doctor stands before a door marked "No. Anfang" (German for "beginning") and "She". It is implied that he is trying to release her, but doesn't know how to do so.

It is revealed in Chapter 94, "Oblivion", that she is Mina Harker's corpse. Because Dracula (later Alucard) did not die once he was defeated, the curse was still active in her, which the Doctor exploited to create Millennium's vampires. However, since Mina hadn't absorbed anyone's blood and soul, she couldn't have been considered as a true vampire. As such, the Doctor could not make vampires such as Alucard.

While "She" is considered the "corpse" of Mina Harker, the image of her mummified and bound in chains implies that at some point, she may have been alive while in captivity (perhaps in a similar fashion to Alucard's mummified state in the Hellsing manor). Despite that, her skeletal remains in "Sorcerian 2" suggests that she had been dead for quite some time.

Trivia

 * There is a metal seal in her skull written in the lower-right corner "SS Gestapo", Hitler's secret police service during World War II, implying the Gestapo was involved with Millenium for some time.
